This is a very interesting discovery. We get asked all the time about feeding our pets. Those of you feeding diets such as The Farmers Dog, JustFoodForDogs and even homemade diets should read the article. This is the leading veterinary research lab on bladder stones (uroliths) in the United States.
UPDATE:
Good afternoon, it appears the intention of this post was misunderstood. The intention of this post was to inform our clients that a new stone was found and could be linked to a certain compound ( choline bitartrate). This compound is found in supplements as well as some foods. It was not intended to make it sound like a common issue or a reason for you to switch your pet's food without talking with your veterinarian. Thank you for all who kindly commented, clearing up some of these concerns. If you have any questions or concerns please reach out to us or your family veterinarian.
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.
