Newfoundland health: what owners should know

The breed is predisposed to hip and elbow dysplasia, cruciate ligament injuries, a heart condition called subvalvular aortic stenosis (SAS), cystinuria (an inherited disorder that can lead to bladder stones) and bloat. A lifespan of roughly 8 to 10 years is shorter than that of smaller breeds. Responsible breeders hip and elbow score both parents, have hearts examined by a cardiologist and DNA test for cystinuria, and they will show you the certificates.

Keeping a Newfie lean is the most useful thing you can do for its joints and heart. See a vet if you notice poor stamina, fainting or breathing that stays fast at rest, straining or blood when urinating, or lameness lasting more than a day or two. Any sign of bloat, such as unproductive retching and a swollen belly, is an emergency.
