BREAKING NEWS -- use caution when feeding your dog fresh food from brands such as The Farmers Dog, JustFoodForDogs and Nom Nom⚠️
The University of Minnesota College of Veterinary Medicine Urolith Center has discovered a NEW urinary stone and the likely cause🔬
The UMN Urolith Center is the laboratory we use for all bladder stone analysis that are conducted for HAH patients and we recently received notification of this new information.
These new stones are called "calcium tartrate tetrahydrate" (CTT) uroliths according to Dr. Lulich (co-director of UMN Urolith Center). Canine patients get "choline bitartrate" (the main compound in CTT uroliths) from fresh dog food and supplements recommended for dogs that eat homemade food.
The data collected by Dr. Lulich and his team showed a link between choline bitartrate found in some of the most popular fresh dog food brands -- including The Farmers Dog, JustFoodForDogs and Nom Nom -- and the newly discovered CTT uroliths.
This discovery was published in April 2025 in the Journal of Veterinary Internal Medicine.
