Newfoundland Cystinuria

Cystinuria in the Newfoundland dog is indicated by the presence of cystine stones in the kidney, bladder or ureter. Failure by the kidneys to reabsorb amino acids results in the formation of these stones.

It is an autosomal recessive disease thus an animal affected with the disease has inherited one copy of the mutation from each parent.

Inheriting only one copy from one parent yields carrier status. The disease is not present but the animal must be bred carefully to prevent creating affected offspring.
