![]() Taurine deficiency in dogs is associated with dilated cardiomyopathy, retinal lesions and impaired reproduction.ĭilated cardiomyopathy is caused by dilation of the left ventricle of the heart that results in the heart being unable to perform optimally. Although most dogs are able to synthesize adequate amounts of taurine, low taurine status has been found in some dogs of particular breeds. In dogs, taurine is generally not recognized as an essential nutrient because they are able to synthesize adequate amounts from other dietary amino acids, namely methionine and cysteine.ĭietary supplementation with methionine has been shown to improve taurine status in dogs with low taurine levels. Taurine deficiency in cats also results in retinal degeneration, blindness, impaired immune response, deafness and reproductive complications. Without adequate dietary taurine, cats will eventually develop taurine deficiency, and a heart condition called dilated cardiomyopathy (DCM) will subsequently develop in a large proportion of deficient cats. Adequate dietary taurine must be provided to cats because of their limited ability to make taurine. Taurine is recognized as an essential dietary nutrient in cats. Many factors affect the levels of taurine found in the body, including dietary intake, body synthesis and individual requirements. Taurine plays important roles in maintaining fluid balance and the ability of the heart to contract. Tissues with the highest taurine concentration are the heart, muscles, central nervous system, retina and platelets in the blood. Many cells are able to make taurine, but the liver is the primary production site. Taurine is a unique amino acid because it is only found in animal tissues and, unlike other amino acids, it is found free in the body and is not incorporated into protein.
