Dogs can synthesize taurine assuming there is an adequate amount of methionine and cysteine in the diet. Specific breeds of dogs, such as Golden Retrievers and Newfoundlands, are genetically more likely to need supplemental taurine due to breed specific heart issues. Dog diets high in lamb or lamb meal, do require taurine supplementation as lamb is low in the essential amino acids necessary for synthesizing taurine. As animal nutrition has continued to evolve, and our pets’ diets have changed, more and more taurine has been formulated into dog diets via a need or as an insurance measure.
Grain-free, vegetarian, and vegan diets have become more prevalent types of dog and cat formulas aiding in the increased use of plant-based ingredients, such as legumes, potatoes, tapioca, etc. These plant-based ingredients are typically low in methionine and cysteine, causing the need for additional taurine supplementation to be used to ensure proper taurine inclusion for both dogs and cats. Taurine has been and will continue to be an essential micronutrient used in petfood formulations for both dog and cats.
