It is not incorporated into proteins but rather is found primarily as a free amino acid in body tissues and circulating in the blood. Back to the top What you can do The FDA is open to additional opportunities for collaboration and welcomes the submission of any information that may aid in our investigation.
Throughout the late s and continuing through the s, many veterinary cardiologists looked at a variety of nutrients, including taurine, in their canine patients with dilated cardiomyopathy. Avoiding Dilated Cardiomyopathy While some breeds should be carefully fed to limit their risk for dilated cardiomyopathy, all dogs should be fed diets that contribute to cardiac health.
Nutrient requirements of dogs, revised National Research Council Taurine concentrations in animal feed canine cardiac taurine diets veterinary journal cooking influences taurine content Spitze, A.
In addition, ConsumerLab is expected to release a report in late on independent quality control testing of taurine supplements. In dogs with taurine concentrations within reference limits, it is unclear whether taurine supplementation is needed, and some patients have recovered with only a diet change.
Multiple factors play a role in the increased popularity of BEG diets. Animals are very efficient at conserving the taurine that is secreted into the intestine by reabsorbing the bile salts back into the body further down the intestinal tract.
Industry Another puzzling aspect of the recent spike in DCM cases is that they have occurred just in the last few years. This weakening can happen for a variety of reasons, but regardless of the underlying cause, the end result is a thinning of the walls of the heart.
Because many owners are unable to recall specific diet details at the time of their appointment, we recommend having owners complete the diet history form at home prior to the appointment so that they can provide exact details on all components of the diet.
All dogs were reexamined 6 months after starting supplementation; survival time and cause of death were recorded for each dog. Getting the word out to owners also is important. Taurine deficiency in dogs with dilated cardiomyopathy: Carnitine-metabolism and function.
Effects of meal feeding and food deprivation on plasma and whole blood taurine concentration in cats Pion, P. Physiological actions of taurine Interaction of taurine with methionine: The previously mentioned survey identified 23 types of BEG diets being fed to dogs with DCM, including home-prepared diets, and not all diets were grain-free diets.
Further, a deficiency may occur even if a diet contains the required minimum amount of a nutrient because of reduced bioavailability or interaction with other ingredients in the diet. Taurine-deficient dilated cardiomyopathy in a family of Golden Retrievers Belanger, M.
For example, a Fanconi-like syndrome associated with jerky treats has been reported 28 but may not have been identified if complete diet histories had not been obtained for affected dogs. Although the results are still preliminary, all but 1 dog for which follow-up data were available had substantial echocardiographic improvement.
The history of DCM in cats can help in untangling what may be occurring in dogs. A recently published article 30 provides an excellent summary of information for veterinarians on reporting suspected animal food issues. In addition, taurine deficiency should be considered as a possibility not just in dogs eating BEG, very-low-protein, or high-fiber diets, but also in dogs eating vegetarian, vegan, or home-prepared diets.
Recently, however, we have heard from veterinary cardiologists who had an impression that they were diagnosing DCM in Golden Retrievers at higher rates than expected and in dogs of breeds typically not thought to be prone to this condition.
Responsible pet owners need to be proactive about providing their dogs diets that are better balanced and of better quality than the average bag of kibble. A board certified veterinary pathologist will review the histopathology slides.The diet should be started from the onset of signs of cardiac disease.
It is recommended that a veterinarian’s opinion be sought before use or before extending the period of use. It is recommended that a veterinarian’s opinion be sought before use or before extending the period of use.

Veterinarians in the School of Veterinary Medicine at University of California, Davis, reported that a deficiency of taurine, an amino acid, was responsible for the development of dilated cardiomyopathy (DCM), a form of heart muscle disease, in cats.
University of California, Davis, veterinarians led a team that has found a link between some popular grain-free, legume-rich dog diets and a type of nutritional deficiency and canine heart disease known as taurine-deficient dilated cardiomyopathy. For owners who elect to feed a homemade diet, it is critical to have the homemade diet carefully formulated by a veterinary nutritionist to avoid severe nutrient imbalances, especially in young.
