Protecting Your Dog’s Urinary Health: Insights on CTT Uroliths from Village Vet
At Village Vet, an integrative veterinary practice, we are dedicated to providing evidence-based care to optimize your pet’s well-being. Recent online discussions have raised concerns about a very rare type of urinary stone in dogs known as calcium tartrate tetrahydrate (CTT) uroliths. As your trusted partner in pet health, we offer the following insights to keep your dog thriving.
What Are CTT Uroliths?
CTT uroliths are a very rare type of urinary stone identified in dogs, primarily affecting small, male purebreds such as Dachshunds or Shih Tzus. A 2025 veterinary study, conducted over four years (2020–2024) with 63 dogs, including 33 surveyed for diet details, suggests these stones may be associated with choline bitartrate, an ingredient occasionally used in certain dog foods or supplements to support cognitive and liver function. The vast majority of dogs are unaffected, but awareness is prudent for those feeding fresh, raw, or custom diets.
How to Safeguard Your Dog’s Health:
Review Food Ingredients: Examine your dog’s food or supplement labels for choline bitartrate, often found in premium or homemade diets. Uncertain about your pet’s nutrition? Our team can provide a thorough evaluation.
Monitor for Symptoms: Signs of urinary stones include straining during urination, frequent urination, or blood in the urine. Contact Village Vet promptly if these occur.
Promote Hydration: Ensure your dog has ample access to fresh water to maintain optimal urinary health and reduce stone formation risk.
Consult Our Integrative Experts: At Village Vet, we combine conventional diagnostics, such as urinalysis, with nutritional strategies to create personalized plans, particularly for breeds prone to urinary issues.
