The most common severe health problem that hounds large hounds are joint related issues. Joints like the patella (or elbow), and hips are prone to dysplasia, a condition where the joint grows or fits together incorrectly. Dogs with dysplasia display a promenant limp, sensitivity to being touched on the legs or whimpering and difficulty walking. This condition is genetic and common among large dogs, so have your vet check your dog’s joints regularly. Left untreated your dog could become lame. Wobbler’s Syndrome, a deformity of the spine, is another large dog issue that can cause your dog to limp or wobble when they walk.

Cardio, or heart related, illness is also a big problem in big dogs. Aortic Stenosis, a narrowing of the heart muscle, and Dilated Cardiomyopathy, which a disease of the heart muscle, are the usual causes of heart related issues in dogs. A lack of stamina and heavy or excessive panting may be a sign that your large dog suffers from a heart related illness, so if your pet displays these signs have his or her heart checked by your vet.

Hypothyroidism is a hereditary disease that is common among large dog breeds. This disease effects the thyroid and hampers the normal growth and development of your dog. This disease commonly occurs between the ages of two and six years old among giant dog breeds like the Newfoundland. The signs of hypothyroidism include lethargy, weight gain, and dandruff or similar skin disease. Dogs with hypothyroidism can be treated with thyroid hormone supplements.

Bloat is another hereditary disease that affects large dogs, particularly breeds with a large, deep chest. Also known as Gastric Dilation Volvulus, Bloat is not only painful but can cause death. Bloat is an emergency disease, caused by a twisting of the stomach that traps the stomach contents and gasses. This results in a rapid swelling of the abdomen. If not treated immediately by a vet Bloat can result in the death of the effected dog, and owners of dogs with deep chests, such as Standard Poodles and Great Danes, should be prepared to handle this situation by keeping emergency veterinarian names and numbers on hand.

Large dogs can be a lot of fun and have a lot of love to share. As much as possible, know your dog’s ancestral medical history and make sure your pet has regular veterinarian check-ups to guard against disease and illness.
