Investigating Owner Use of Dietary Supplements in Dogs with Canine Cognitive Dysfunction

SIMPLE SUMMARY: Canine cognitive dysfunction is considered the canine equivalent to human Alzheimer’s disease. It is a growing concern in veterinary medicine, as it affects many aged dogs. Dietary intervention with different diets and supplements may improve clinical signs and prevent further degeneration. Using an online questionnaire, we found that even though few owners were willing to change their dog’s main diet, many of them added supplements such as oils and vitamins. Consulting a veterinary surgeon when using dietary supplements is important as it allows for evidence-based recommendations to be made. ABSTRACT: Canine cognitive dysfunction (CCD) is becoming increasingly recognized in veterinary medicine, as dogs live longer and with CCD being highly prevalent among the elderly dog population. Various studies have shown that diet and dietary supplementation can positively influence the clinical signs of CCD, especially if given at an early stage. The aim of this study was to investigate owner use of dietary supplements (DSs) in dogs with age-related behavioral changes. An observational study based on an online questionnaire for owners of dogs with age-related behavioral changes was performed. Out of a total of 394 owners who completed the survey, after noticing age-related behavioral changes, over half of the dogs received DSs (54%), whereas only 8% reported changing their dog’s base diet. The most used DS was fish oil (48%). The use of DSs should be discussed with and monitored by veterinary surgeons since many geriatric patients have multi-morbidities, may have specific nutritional requirements and receive multi-faceted medications.
