In summary, if you are feeding your dog a raw or home-cooked meat-based diet, then chances are they may be getting enough taurine however, if your furry friend is only getting kibble then supplementation may be advantageous to ensure your pet is in optimal health. A few of the breeds that are predisposed to this type of potential issue are: Newfoundlands, Scottish Terriers, Chihuahuas, Basset Hounds and Australian Shepherds. Plus, some dogs have an issue metabolizing amino acids, which in turn may cause a taurine deficiency. It is also important for us to note that larger breeds produce less taurine naturally than small dogs so ultimately some dogs just cannot produce the taurine within the body that they actually require, so supplementation may be necessary. It can be more susceptible in certain breeds, like Golden Retrievers, Newfoundlands, Saint Bernards, English Setters and certain lines of Spaniels. This is true for cats, and may now also be true for dogs. It affects some dogs and has been known to be linked to taurine deficiency since 1997. Taurine deficiency is one cause of a heart condition called dilated cardiomyopathy (DCM), where the heart muscle thins and the chambers become enlarged. Some of the symptoms of DCM are: fatigue, heavy breathing with exercise and coughing. Have you ever heard of DCM (Dilated Cardiomyopathy)? This is where the heart muscle thins, and the chambers become enlarged. Any break in the chain will increase the chances of the dog developing a taurine deficiency. The process for a dog to produce taurine depends on a chain of events, they need to make cysteine from methionine and from cysteine comes taurine. ![]() Dogs, unlike cats, can produce their own taurine, however, just like us humans their ability to do so decreases with age and may be hindered by other factors. It is an essential component of bile acids, which are produced in the liver and used to breakdown fats from foods which are consumed. Taurine is an amino acid that occurs naturally in meat and it’s abundant in the brain, eyes (namely the retina), muscles and organs. As mentioned before, with the Golden Retriever, the research shows that approximately 40-50 of the cases are actually testing with low taurine levels. However, the cause is still in question when it comes to goldens. The authors noted that some of these issues were discussed during pre-publication peer review and/or in the published article.Some of you might know already that cats cannot produce their own taurine, so supplementation for them and getting taurine through dietary routes is critical, but what about our canine friends? It seems, instead, that the DCM showing up in Golden Retrievers leans towards being food-related. This does not alter our adherence to PLOS ONE policies on sharing data and materials.Ĭoncerns raised about the study are outlined below. There are no patents, products in development or marketed products to declare. Collectively, this did not influence the collection or interpretation of results in this study. Since the time of article submission, JAS has received research support from Nature’s Variety Inc. PLOS ONE RESEARCH ARTICLE Development of plasma and whole blood taurine reference ranges and identification of dietary features associated with taurine deficiency and dilated cardiomyopathy in golden retrievers: A prospective, observational study a1111111111 a1111111111 Eric S. AJF has a contract with the FDA on unrelated research. The Veterinary Medical Teaching Hospital at UCD received funding from Royal Canin to support a resident, and from Nestlé Purina PetCare to partially support a nutrition technician. A resident on the Nutrition Service, mentored in part by AJF, received funds from the Hill’s Pet Nutrition Resident Clinical Study Grants program, matched by the Center for Companion Animal Health, School of Veterinary Medicine at UCD. AJF received funding from Nutro for graduate student training. AJF received remuneration for lectures or as an advisor on behalf of Nestlé Purina PetCare, Mars Petcare, Synergy Food Ingredients, the Mark Morris and Pet Food Institutes. In response to the concerns about declaration of potential competing interests, the authors have provided the following update to the Competing Interests statement:ĪJF is the Scientific Director and JY is the Technical Director of the Amino Acid Laboratory at the University of California, Davis (UCD) that provides amino acid analysis on a fee for service basis. After this article was published, concerns were raised about undeclared competing interests, and about the study design and conclusions. ![]()
