Quick answer
Cystinuria is a medium-severity condition documented in the Newfoundland. It has a hereditary component, so ask breeders for health-screening documentation. Estimated treatment cost is £1,000-£3,500.
Cystinuria can affect members of the breed within the Newfoundland. Common indicators include straining to urinate, blood in urine, and urethral obstruction. Cystinuria is an inherited defect in renal tubular transport of cystine and related amino acids, leading to cystine crystal and stone formation in the urinary tract. It predominantly affects males, who are more prone to urethral obstruction. It typically becomes apparent at 1-8 years. The giant frame of the Newfoundland can accelerate progression in weight-bearing conditions, making early diagnosis particularly valuable. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £1,000-£3,500, making comprehensive pet insurance a practical consideration.
If your Newfoundland is showing any of these signs, consult your veterinarian promptly.
Dissolution with D-penicillamine, tiopronin, or dietary management (low-protein, alkalinising diets) can dissolve some cystine stones. Surgical cystotomy for stones that cannot be dissolved. Lifelong prevention diet is needed.
