Questions related to Dogs
If the cow is bitten by rabid dog is it safe to consume its milk (If there are any specific literature available kindly share).
Dear all, I have to draw the complete pedigree of a high number (>40) of dogs in a study regarding genetic diseases, so I started drawing the pedigree using the R package kinship2.
The problem is there are many common ancestors between the tested animals, and as soon as I add the grand-parents of the subjects the tree gets all "scrambled up", with dashed lines connecting the same individual present more than once in the pedigree and drawn in different spots of the tree. I know that human genealogic trees are usually far more simple than this scenario and this package should work at best.
Manually adjusting the branches to avoid subjects duplication is quite hard to do, so I was wondering if there is an easier way using a different software (possibly free) or a different R package best suited for complex animal pedigrees.
I am doing my MSc thesis and it is based on two questionnaires. I am comparing opinions on canine hip dysplasia of vet surgeons and CHD affected dog owners. Both groups had questionnaires with matched questions (for example owners had a questions: “at what age was your dog diagnosed with CHD?” & the vet questionnaire had a questions “at what age dog CHD is most commonly diagnosed”?) and same answers.
The problem is the number of respondents. I have 121 owner questionnaires and only 31 vet questionnaires. I am planning to do cross-tab and chi-square test, but not sure how to:
1. match two different surveys on spss;
2. compare the different response count.
any suggestion will be greatly appreciated
One of my undergrads created a phylogeny based on few human hCov19 and few from other hosts including bat, panguline, and dog. He found two viral genomes one from an Australian and one from a Singaporean clustered with the one isolated from canine. This seems interesting! Any study to support this finding?
Can anyone suggest any ensembling methods for the output of pre-trained models? Suppose, there is a dataset containing cats and dogs. Three pre-trained models are applied i.e., VGG16, VGG19, and ResNet50. How will you apply ensembling techniques? Bagging, boosting, voting etc.
I've seen evidence of strange behavior among people who walk their dogs on trails in parks or seminatural areas in my suburb. People will carry plastic bags for picking up their dogs' feces but then, instead of discarding the filled bag in a bin, they will throw the bag away like litter, and often in the vicinity of the bins. (I've never actually seen anyone do this, just the evidence thereof.) This behavior creates a more serious pollution issue than not cleaning up after your dog since the plastic bags don't biograde. Have there been studies on this or similar counterproductive behaviors?
I'm looking for a dataset of natural images, with no specific requirement on the type of scene, designed for the task of detecting (automatically or visually) the presence and position of small objects. This could come for example from an eye-tracking experiment where participants are tasked to e.g. look for dogs in a picture taken with a camera, or an image segmentation dataset. The point is that the task is challenging/the category is rare/the segmentation area is small and hard to find. Each scene would ideally be associated to a label or set of labels indicating the object/s to be searched for, an explicit position or the segmentation masks are a plus but not required.
This questionnaire is for dog owners. This is part of my disseration for animal science. I am looking to see if canines with anxiety are more at risk of becoming ill. The data will only be used for the purpose of this disseration. even if your dog does not have any anxiety please fill in as it may just prove anxiety has no effect on a dogs health.
Is there any review paper or book chapter/book available on the topic Parasites in the nervous system of dogs and cats?
After few years I was re-sequencing a fragment of the D-loop of dog mitochondrial DNA and I found a heteroplasmy which was not previously observed at the same position. In the attached picture there are two chromatograms of the same sequence from the same dog, from the same blood sample. The chromatogram above is from 2014 and the below one is from 2021. The isolated DNA is the same. The heteroplasmy was observed in several samples at the same position in other dogs' sequences, however in all sequences the quality is poor due to the double peaks in the baseline. I don't understand why the signal dropped only at one position, and suddenly raised in the next position.
The attached pictures are those of a swollen dog's ear.
We observed that the ear of our local dog is swollen without visible lesion, cut or scar.
However, it seem there isn't abscess or pus in the observed mass.
What could possibly be the cause and how can it be treated?
thanks alot for your support
I got up with a doubt , for simulation normally we use ansys or abacus of tensile testing . But when it come to polymers tensile testing which software need to be used. as the infill pattern will change the effect of fracture , what software we need to use for simulating tensile testing of specimen's. if we go with ansys the dog bone will be treated as simple structure but not infill parameters. can some one clarify my doubt please
need software suggestion to do testing simulation.
Hello, I was wondering whether there is a non-invasive technique to apply a GPS collar to a wild dog. I was thinking about e.g. a tree hole with some food where they have to put the head through the (elastic) collar to get in, which then automatically attaches to the dog? Or maybe remote controlled (with the help of a camera trap) - like a reversed drop-off mechanism? Or anything else... Thanks!
For my college assignment I need to produce a leaflet detailing the information required when assessing a dog for a diagnosis for hydrotherapy and physiotherapy and the impact this has on the treatment. I was wondering if anyone could help me out?
I've build a Conv1D model to classify items into 6 categories (from 0 to 5). (simplified example)
I use therefore a CrossEntropy loss function that penalizes the errors with high probabilities and also the low probabilities associated to right answers. And that is exactly what I was looking for.
But CrossEntropy considers the classes as independent, while I'd like reduce the loss for an error where model predicts 0 (cat) while it is 1 (dog) and increase the loss when the model predicts 0 (cat) when the true answer is class 5 (fish).
Is there a way to embed the 'class proximity' in the loss computation of a classification problem, so that a error between classes 0 and 1 will be less penalized than an error between classes 2 and 5 ?
Many thanks in advance for any help !
I wish to direct the researchers to think of using a dog's lung structure or cells to guide us how to develop a medicine or vaccine or treatment for diseases such as corona.
At University, we are doing an assignment on the development of certain behaviours from wolves to dogs. My friend made an excellent point. When wolves were domesticated, they were bred to remove aggression and to increase tameness. But when people now breed dogs for aggression, then they lose control over their dogs, lose the tameness (to an extent) there fore are almost "undoing" domestication with their dog.
I just wondered if there were any studies that have looked into this, or if anyone had any thoughs on the subject.
I'm looking for a date range of when domestic dogs were brought to Ireland and who brought them there. The closest I've gotten is when the so-called "lap dogs" were brought in and there is no date for that. Yet I've found information that "Irish hounds" existed back in AD 393 so they had to have gotten there before then.
I am culturing MDCK dog kidney cells. I am trying to express shRNA to knockdown target genes. There are so many shRNA design tools for human, mouse and rat species. I haven't been able to find a good way for dog species. Does anyone know any good tool such as website or algorithm? Thank you in advanced!
I would like to test some markers to identify spermatogonial stem cells in cats. Should I choose the markers that will be tested from known human or dog markers? Which species will most likely have antigenic similarity to cats?

Dogs, properly trained, discover easily and infallibly if a person is infected with SARS-CoV-2 the virus that causes the COVID 19 disease. Is it possible to build an artificial nose to detect those infected with the virus SARS-CoV-2 as dogs do?
I am interested in pursuing my masters thesis research on the use of Tilapia skin grafts in wounds of dogs. Any inputs would be appreciated.
I read a few articles related infant & dog's auditory preference. They both mentioned "baby talk" could be more attractive to infant & dog. And my team and I want to find out the reason from evo-psych. We already know one of necessary condition is high pitch, and had some data about high pitch preference for dogs (we took gaze duration to be parameter).
Our project focus on evo-psych puzzle, so we want to exclude the physical or physiological reason to explain why dog prefer high pitch. I tried to do some reviews to know physical trait of high pitch. But I almost found nothing help because I barely know the domain knowledge of acoustics. So if physical trait of high pitch could explain why mammal like human and dog has such preference, then we should reschedule our project.
Thank you for response such fundamental question.
Toxocara are described as very frequent in dogs and certainly across the world overall prevalence of T canis is described as 11.1% in a paper by Ali Rostami and others in Advances in Parasitology Volume 109(2020) pages 561-583. However I can find no recent papers of the prevalence of this parasite in the UK (I am not working in academia and do not have access to all references). This is important because the use of potent anti-parasitic treatments often on a monthly or three-monthly basis is extremely widespread in the UK. Some anti-parasitic drugs leak into waste water or the wider environment and may be causing eco-toxicity effects on insects soil nematodes etc.
I am doing my Psy.d on the social validity of the intervention of animal assisted therapy (dog) on a PTSD population in the province of Quebec. The only close tool of measure I found is the treatment acceptability ans adherence scale (wich was made for anxiety at the base).
Anyone is aware of a complementary tools that I could use.
I have transcriptome sequences of parasites found in dogs. I use the blood from the dog to amplify the parasite so I would like to make sure that the sequences that I am using are of the parasite and not the dog?
Which bioinformatics software can I use and how do I go about it?
While doing my research work, I have noticed that the D- dimer levels of normal animals (dogs) are given in different ranges in different publications. Is there any variation occuring in d dimer levels due to the application of different methods? . And what is the normal serum D-dimer levels in dogs? I am so confused with the reference range of serum D - dimer. Thank You in advance.
Dr. Caleb Bryce and I have organized a canine science symposium for the Society of Integrative and Comparative Biology (SICB) meeting January 3-7th, 2021 in Washington DC (http://www.sicb.org/meetings/). Attached you may find a poster with a list of the speakers for our symposium which will be held January 7th, 2021.
Abstracts will be due late August to early September 2020. You do not have to be a SICB member to attend this meeting, and you can also register to attend for a single day.
If you cannot attend part or the whole meeting, may I ask that you help us spread the word about it by forwarding this information and poster to potentially interested parties?
Our hope is that dogs take over SICB 2021, hopefully with your help!
Please do let me know if you have any questions.

I'm a veterinarian who ended up in the bioinformatic world as I am analyzing the RNA-Seq using samples from colons of 2 groups of dogs; 1 control group of 3 beagles where I have sent 3 colonic samples with histopathology as normal colon mucosa and 1 disease group of 3 dogs where I have sent 1 set of diseased and normal colonic sample for each dog with histopathology as diseases and normal colon mucosa. Basically I have 3 replicates from 2 groups of dogs, but with 3 different conditions (1 condition of normal dog colon, 1 condition of diseased dog with diseased colon, 1 condition of diseased dog with normal colon) making it up to 9 samples, which warrants the use of edgeR since I have less than 12 samples.
The colonic RNA samples were sent for RNA-sequencing in another DNA research lab and I honestly am not sure which protocol they have used; the information received was the sequences were proceed using CLC genomics workbench 12 to produce the excel file with total count, RPKM, TPM and CPM.
Machine used was Illumina HiSeq 2500 with single-read,50bp library; and sequenced with 15 million reads, where FASTQ file was retrieved.
The flow of RNA sequencing was done as below:
1. From FASTQ reads, the Illumina Adaptor was removed
2. From FASTQ reads, the unreliable bases were removed
3. The reads were mapped on the CamFam reference
4. RPKM was calculated.
I am in a dilemma now if I should re-process the raw FASTQ files myself, or by just using the current Excel file; as I do not have access to supercomputers in my facility.
I am trying to analyze the excel output using Rstudio with the EdgeR package for normalization and hopefully DGE analysis, but I'm pretty unsure of at what point my current excel data is at. Will I need to normalize it, or should I not be using the Excel but the raw FASTQ for the EdgeR instead (as the user manual says to not use FPMK in the EdgeR, but the raw data instead). Will total count and total read numbers be suffice to come out as a raw data for EdgeR?
I have up to 20,000 genes to analyze, I wonder if I do have sweet time to start from raw data.
The sample cannot be reformed to the dog bone shape for testing purposes.
I have tried to stick sandpapers with epoxy to the ends of the specimen but it still slipping .
roughening the ends of the sample doesn't prevent the slippage aswell!
sample thickness cannot be reduced!
Elements of Ca, K & Mn were detected in cystolith from a 3 year old male Dalmatian dog by EDXRF method. Can anyone tell me which cystolith it is?
I try to culture Trichomonas tenax from dog's mouth in Diamond's medium. I have used both home-made and commercial media. I have live cells isolated from a few dogs in these media. However, they all die off after being diluted into new medium. What have I missed? Any advice is greatly appreciated.
Hallo, i'm working on small university project on Human Visual Attention cues and how dog use this to change their Behavior. My question is: what is the Attention Cues used between dogs in a their social Behavior? Such as when the dogs going around a place grouped, how this dogs interact with other dogs? I think the this topic lays the foundation of "Human Visual Attention cues and how dog use this to change their Behavior".
I am beginning to compile a methodology for testing personality in domestic dogs for a dissertation looking at the role that personality plays in determining the success or failure of assistance dog training.
At this stage, I am considering comparing working Labrador retriever assistance dogs for the blind, failed trainees that have been rehomed and a control group of companion dogs.
I can't find many studies regarding gallbladder emptying times in dogs. In particular, I wonder if this observation has ever been used as a contribution in legal cases, for example to speculate on the time of the last meal. I am examining a dog killed by a gunshot wound: the stomach is full of food only partially digested, but the gallbladder is not empty (the bile duct was normally patent). Can I infer something about the time elapsed since eating its meal?
I have heard it is very important when do animal experiments, particularly in dogs, to select a internationally recognized provider as Marshall. Apparently there are small differences on the homegeneity of the genetics of the breeding despite they are all beagles.
Seems that Marshall are too expensive and therefore CROs using these animals despite credible and quality are more expensive than others as for example CROs price diffeerence between Europe or India as example
So then question is: any of you have experience on that? Is that much the difference? Do you recommend not to use beagles that has not sufficient credibility regarding beagle breeding homogeneity? Are AAALC accreditations suficient to guarantee he homogeneity of the breeding? Is there any specific ethical rule or regulatory rule that I should take into account for generation of the data?
Well, I think that animals and us (animals too) are both intelligent and rational, we just evolved, back in time we were "dumb" as we think animals are but who thinks this way is wrong, you don't see animals throwing themselves from edges, when a dog goes to a precipice they don't jump to death, they have the ability to rationalize situations, dogs can cross streets, help blind humans to walk through cities and even find cancer presence only by smell, and many other things that we can't. In fact, what I think that differs us from them is the dexterity achieved by humankind, the know-how acquired by us is on another level, we were able to think, to question and to answer that questions, what really differs us is our philosophy and science, our mind and brain evolved too much and got the capacity of creation.
Came across a case of subcutaneous swelling located between the xiphisternum and umbilicus in a 3-month old male German shepherd. According to the animal owner, the swelling was since birth and growing progressively. General health condition of the animal was otherwise healthy. Palpation revealed a reducible mass with 2-fingure defect immediately caudal to the xiphisternum directly over the linea alba. Sonography & abdominal radiographs confirmed herniation of the stomach and associated viscera. Please suggest an exact terminology for this defect.
Covid-19 is said to have originated by mutation in a 'wet market' in China. These may contain a wide range of live or dead animals, including dogs and cats. Does anyone know what animals, wild, feral or farmed, have been implicated as possible sources?
I am doing a GWAS analysis of european bison's a dog's SNPs. Right now I am doing multiple data clean up, according to previous studies and what I have learned.
I was thinking, if it is ok to test HWE and discard data that does not fit if I am working with animals, where mating is controlled and inbreeding coefficient is high?
And what about tests for population structure etc.? It is obvious that there is going to be some structure in reintroduced and domestic animals. I don't want to loose any important data and I want to be sure, that I have done everything correctly.
Thank you for your help.
I need to provide the number of haplotypes in my data for the hapFLK test (Fariello et al. 2013, Genetics).
I try to find the number of haplotypes in my whole-genome dog and wolf data (21Mb SNPs) with fastPHASE cross-validation procedure.
I created a test file (attached) and ran fastPHASE with different settings including:
./fastPHASE -T10 -KL3 -KU30 -Ki2 -Ks50 -Km1000 test.PHASE
However, fastPHASE always outputs K15, which I believe is incorrect because it never changes even if I change the input file. It also never outputs a file with _kselect extension, as it should. Maybe there is a bug. I use fastPHASE 1.4.8, it is available here http://scheet.org/software.html I tried to contact the author of the software, but have not got a response.
I also tried to use PHASE program, but it is extremely slow and cannot handle even a subset of 7K SNPs.
Could anyone share his/her experience with estimation of the number of haplotypes with fastPHASE or any other program?
Just this week, I noted two cases of extreme mange in coyotes in my research area. Coincidentally, I had camped out by a cattle trough in the area overnight in September and three days later both my dog and I had a bad case of Scabies, (same thing as mange).
Has anyone dealt with this in wildlife species? What organization do I contact with my findings?
I'd appreciate advice.
I have a some draft for a title questions ...

I have a dog who loves cats, he is a puppy and from 3 to 9 months he has been exposed to a few cats. He mostly chases them benignly underneath things and then cries to play with them. He has been able to put his nose on the friendliest indoor cat when he is lounging. Where does this go next?
I am gathering bibliography around home range measurement with the traditional method, alias observation.
- Do you have studies to suggest?
- In particular, are you aware of recent publications, say within the last 15 years, still using observation?
- Do you think this can still be a valuable way to measure home range size of some species, as, free-ranging dogs living around a neighbour?
Sci Am October 2019 issue has an article, Is Death Reversible? by Christof Koch of the Allen Institute for Brain Science. At p. 36 he writes; `... there is no credible evidence that apes, dogs, crows and bees have minds sufficiently self-aware to be troubled by the insight that one day they will be no more.’
Relate this to a preceding question: Is abstraction a collective invention of human society? Suppose that abstraction is an invention of society’s networked minds of hundreds or thousands of generations. Then the difference between `apes, dogs, crows and bees ‘ and humans is that humans acquire the abstraction `death’ from the store of abstractions devised collectively by society. If so, humans do not differ from `apes, dogs, crows and bees ‘ in understanding death due to superior individual cognition that arises during an individual lifespan, but rather from an insight collectively arrived at by networked minds over many generations.
For an individual human, it is difficult to separate from knowledge that which has been acquired by means of language. Paul Feyerabend in 1993 in Against Method, observed ` … describing a familiar situation is, for the speaker, and event in which statement and phenomenon are firmly glued together.’ Perhaps that applies to the abstraction `death’? Or not?
I have changed my extraction method, changed my PCR master mix, changed my water. also I have modified my PCR program but nothing works. and when I got a single band and sent it for sequencing they didn't give me a clear, reliable read.

In India about 20000 people per year die due to rabies and there is an urgent need to control this disease.
The primary source of infection is stray dogs and there is an urgent need for vaccination of stray dogs with rabies vaccine for effective immunity is for 3 years.
Looking at the similarities that dogs and babies share. How do reward and treat behavour controlling cross from one to another ? How do these practices feed into normative ideas of success and failure ? Do practices of 'petification' (halberstam) aid the adult/owner or the child/pet ?
I am thinking of creating a search engine to help people find a movie or similar movie based on the snippets of the story. For instance, if a user type in "movie about dog waiting a long time for his owners to come back", the result should return "Hachiko" , "Eight below", "Lassie" etc. However, it would have been better if we can use data mining method to actually search it based on the plot of the movie not keywords. What is the best solution for this work?
There are many health benefits of sharing your life with a dog. I made a summary here

But are there any good evidence based scientific studies?
I performed a compound PK analysis in Dog and Monkey. The PK modeling is based on non-compartment analysis (NCA) and, I found that the compound's t-half time much longer than its mean residence time (MRT).
I was wiondering if anyone also observed this phenomena before and could please give me any suggestion to explain the data.
Thank you so much!
I found that it takes 4-5 months for the dogs jaw bone to become completely decalcified , but this is a long period.
I'm having problem growing bone marrow MSCs isolated from dog. I froze the cells at P1 and recently started to revive them. All four batches of cells (from 4 animals) are growing okay in T25 flasks at P2. But once I passage them and grow them in a larger flask T175, 2 out of the 4 batches do not attach or deattach from the plate, and there are cell debris in the medium. The 2 batches of cells that deattached were isolated from younger dogs than the other two. But only 5 days younger.
Any one have a clue on why this is happening? Should I keep use T25 four further passages instead of transfering them to large flask?
I am a civil servant working in the special department related to stray dogs. As the conductor of the description of the mutual assessment to get dog-food supplies, I have to be accurate about the reason I need to ask for dog-food protein rate around 18-22% with the detail of it containing not less than 18% biologically originated protein. Can you please inform me about the proper legislation referring it? A thousand thank you in advance.
For a project I need DNA samples from different organisms (cat, dog, horse, plants etc).
Do any of you know of companies that sell DNA from different organisms?
Many thanks in advance!
I came across two deformed Rhipicephalus sanguineus fed females, please see attached photos. Female 2 weighs 0.265grams and the weirdest one, female 1, 0.209g. These were just slightly lighter weights than normal females. Have you ever seen this? It does not look like gynandromorphism to me. Maybe dog bite trauma?!
They started incubation to lay eggs and 3 days later they started oviposition. Eggs are healthy looking. I can share the specimens and the progeny if any interest. I can't take time to dive into this, but I thought that someone here might be interested.
all the best,
I am planning to insert a mouse gene into dog genome via CRISPR cas9 to re-activate cell proliferation pathway. Not sure where to begin. If anyone who has done a successful CRISPR Cas9 experiment before, can you please share your experience with me e.g. how to set up the experiment? any help would be highly appreciated.
