Facial expression in animals is a suggested method to assess the subtle facial changes associated with pain. This study aimed to evaluate postoperative pain and establish its correlation with facial action units (AUs) in female dogs undergoing elective ovariohysterectomy (OVH) treated with cannabidiol alone or in combination with meloxicam. Sixty h...

This study aimed to assess changes in the surface temperature and physiological parameters of cats exposed to a fear model involving negative dog–cat interactions, receiving three pharmacological options: a single dose of cannabidiol, gabapentin, or synthetic facial pheromones. The surface temperature of the upper and lower limbs, facial, dorsal, a...

Mothering and bonding represent fundamental aspects of survival and development in domestic mammalian species. The mother-young interaction immediately after parturition is a critical event where the mother establishes selective care for the offspring, and the newborn responds to maternal stimulation. To develop this bond, maternal responses such a...

Pain is one of the main events that ch allenge animal welfare due to its alterations in the five domains, including the mental state. Because each species perceives and reacts to pain differently, the study of pain in veterinary medicine has focused on using tools that allow it to be recognized quickly and objectively. Ethology is part of these too...

Recognizing that nonhuman animals are sentient beings has increased interest in studying their emotional state. Similar to humans, research has shown that some nonhuman mammals can modify facial expressions by contraction/relaxation of facial muscles according to their affective state. From a neurophysiological perspective, emotions are processed i...

The growing interest in managing and recognizing pain in animals has led to the search for more sensitive methods to evaluate it, especially because some species conceal any visible changes associated with pain or are not easily assessed. Research has shown that an animal's facial expression changes when exposed to painful stimuli. Thus, developing...

La rabia es la zoonosis con mayor impacto sobre herbívoros domésticos, provocando en América Latina pérdidas económicas de aproximadamente 97 millones de dólares anuales. En esta región, el vampiro común (Desmodus rotundus) es un reservorio del virus de la rabia y se considera su principal transmisor al ganado. El objetivo de este estudio fue anali...

Pain management requires the identification of certain indicators to recognize pain. Various tools have been suggested to achieve an objective evaluation, including infrared thermography (IRT). The objective of this study was to assess the facial thermal nociceptive response produced by the use of cannabidiol (CBD) alone and in combination with mel...

The Facial Action Coding System (FACS) is an anatomically based system to study facial expression in humans. Currently, it is recognized that nonhuman animals, particularly nonhuman primates, have an extensive facial ethogram that changes according to the context and affective state. The facial expression of great apes, the closest species to human...

From 2019 to 2021, twenty D. virginiana were collected from the state of Colima, Mexico. Post mortem, parasitological, and histopathological studies were performed to identify and describe their lesions and findin...

Perinatal mortality occurs in all species. In dogs, mortality rates have been reported to range from 5 to 35%. Electronic fetal and uterine monitoring has recently been used in domestic animals to monitor the mother and newborn before and during parturition. In this way, the fetal heart rate and uterine dynamics can be monitored. This study evaluat...

This article aims to analyze the biological and communicative function of facial expressions and their relation to emotions in mammals. Facial expressions and their causes constitute an important yet largely unexplored field of scientific research. While the clinical usefulness of these expressions for recognizing pain in many species has been demo...

Simple Summary Due to anatomical differences in the skull of the water buffalo (Bubalus bubalis), the currently applied mechanical stunning methods in cattle (genus Bos) have shown to be ineffective in buffaloes by not damaging vital cerebral structures associated with consciousness. The present review analyzes these anatomical particularities of w...

Simple Summary Preventing neonatal mortality is a critical aspect of canine perinatology. Among the leading causes of mortality, a low vitality score at birth, hypothermia, hypoxia, and hypoglycemia can be mentioned. This study aimed to assess vitality, blood values, and the degree of meconium staining on newborns’ skin concerning their birth weigh...

Simple Summary Although ruminant newborns are a precocial species, they are susceptible to hypothermia and neonatal mortality during the first hours of life due to intrinsic and extrinsic factors that challenge their thermostability. Several mechanisms are activated when the organism perceives a temperature decrease, such as vasoconstriction, shive...

Simple Summary Current acute pain assessment protocols in domestic animals require the use of a suite of methods to evaluate the multidimensional components of pain. Thermal imaging is a method that assesses the physiological response, via heat production, to a noxious stimulus. This may correlate with the affective experience of acute pain. Since...

Simple Summary Caffeine is a stimulant used in humans and animals to improve newborns’ respiratory and neurological responses. The use of caffeine after birth could increase neonate survival. However, due to the immature systems of animals at birth, caffeine use can have different results. This review aims to understand caffeine’s effects on respir...

Simple Summary Vitality is a characteristic that in newborn animals demonstrates their vigor and their general state of health (heart rate, respiratory rate, skin color, time that they take to stand up) during the first hours of life. It can be measured by numerical scores based on some scales made for babies and then adapted for various animals. V...

Simple Summary Euthanasia is a common procedure performed by veterinary professionals, which carries important ethical, moral, and legal challenges. In the case of dogs with chronic and terminal illnesses, the decision is highly influenced by owner-related perspectives, financial constraints, caregiver burden, and emotional attachment. Likewise, al...

Over the past five years, different animal species have been used to study pandemics, such as the 2019 Coronavirus, diabetes, and obesity. Through murine, primate, porcine, and even aquatic models...

Simple Summary Oxytocin is one of the most important hormones in birth and lactation. Its importance lies in the fact that it is also involved in various bodily functions around parturition and establishing maternal behavior. We aimed to analyze all the facts involving oxytocin regulation and participation in different peripartum situations in dome...

The use of cannabinoids in both veterinary and human medicine is controversial for legal and ethical reasons. Nonetheless, the availability and therapeutic use of naturally occurring or synthetic phytocannabinoids, such as Δ⁹-tetrahydrocannabidiol and cannabidiol, have been the focus of attention in studies regarding their medical uses. This review...
