ABSTRACT Long-chain omega-3 fatty acids from fish oil and other marine sources appear to be capable of modifying inflammatory and immune responses in dogs. Information is provided on the capacity of dogs to metabolize omega-3 fatty acids and the effects of omega-3 fatty acids on skin and coat, inflammatory responses, and neurologic development in puppies.

    ABSTRACT: To determine the effect of fish oil supplementation on circulating concentrations of adiponectin, leptin, insulin, glucose, triglyceride and cholesterol in healthy dogs. Twenty healthy adult dogs were administered 220 mg/kg of a fish oil supplement once daily for 30 days. At baseline, on supplement and 10 to 20 weeks off supplement, dogs were examined, body condition scores determined (range: 4 to 6), body measurements recorded for % body fat calculation and fasted blood samples collected. Serum concentrations of the measured individual and total n-3 polyunsaturated fatty acids increased following supplementation (P<0·001). Mean serum adiponectin concentration on supplement was 3·4 µg/mL (95% confidence interval: 0·8 to 6·0; P=0·006) higher than baseline, and 5·3 µg/mL (2·0 to 8·7; P<0·001) higher than off supplement. Concentrations of adiponectin off supplement were not different from baseline. There were no significant differences in weight, body condition scores, % body fat and concentrations of other measured analytes between baseline and on supplement. Fish oil supplementation significantly increased circulating concentration of adiponectin in healthy non-obese dogs. Further investigation is warranted to determine whether this effect may be extended to obese dogs and to evaluate the potential role of fish oil supplementation in the management of disorders associated with low circulating adiponectin concentrations.

    ABSTRACT: The analysis of serum cholesterol and triglycerides was performed in 20 healthy mongrel dogs, 10 male and 10 female, before and after supplementation for 30 days with fatty acids of long chain polyunsaturated derived from omega-3 n (497mg docosahexaenoic acid and 780mg eicosapentaenoic acid). The serum cholesterol presented a significant reduction after supplementation in both sexes (271.6±79.8mg/dL; 236,2±67,6mg/dL, before and after supplementation respectively). Regarding serum triglycerides, there was a reduction only in females (57.8±12,1mg/dL; 45.2±7,8mg/dL, before and after supplementation respectively), with no effect of supplementation in males.

    ABSTRACT: Background Treatment of symmetrical onychomadesis (symmetrical lupoid onychodystrophy) is a challenging task for dermatologists. The acute phase is characterized by sloughing of claw plates and loose claws have to be removed and secondary infections treated. The goal of long-term treatment is to allow claws to re-grow with normal quality and to achieve life-long lack of recurrence. The aim of this randomized treatment trial was to see if adding fish oil or cyclosporine to a diet rich in omega-3 could improve the treatment outcome of symmetrical onychomadesis in Gordon and English setters. All dogs were fed Eukanuba Veterinary Diets Dermatosis® exclusively during the six month treatment trial. The treatment outcome was measured as the change in number of healthy claws during treatment, as well as the long-term effect on hunting ability and recurrence of onychomadesis. The hypothesis was that cyclosporine provides a stronger and different immune modulating property than fish oil and therefore would give a better treatment outcome in dogs with symmetrical onychomadesis eating a diet rich in omega-3 fatty acids.ResultsSix Gordon setters and one English setter were treated with 5 mg/kg cyclosporine once daily for six months and seven Gordon setters were treated with 10 ml Dr Baddaky fish oil® once daily for six months. All dogs were evaluated every month and the numbers of healthy claws were recorded.There was a statistically significant improvement in the number of healthy claws after six months of treatment with a median increase of 13.5 claws for both groups. However, there was no statistically significant difference between the two treatment groups regarding the improvement in number of healthy claws, as assessed using the Wilcoxon rank-sum test (P¿=¿0.15). Dogs in the cyclosporine group had a median increase of 10 healthy claws after six months of treatment while the median for the fish oil group was 14. Long-term cure was not achieved with either treatment.Conclusion Cyclosporine and fish oil appeared to be equally effective in treating symmetrical onychomadesis when the dog is fed a diet high in omega-3.
