In general, the Swissy is a healthy breed. However, certain health issues are of concern and should be discussed with your breeder and veterinarian.
As with many large, deep-chested breeds, gastric torsion or bloat, is a concern. Bloat is a gastro-intestinal condition in which the stomach rotates on its axis, causing a loss of blood flow and a build up of intestinal gasses. The condition is a veterinary emergency. Be sure to discuss the symptoms of bloat with your breeder and your veterinarian. Also discuss recommended preventative measures, such as splitting feedings into two or more smaller meals, feeding from raised dishes, and limiting exercise before and after feeding.
Hip and elbow dysplasia are also evident. Most breeders perform radiographs and seek certification from the Orthopedic Foundation for Animals (OFA).
Certain eye anomalies, such as distichiasis, entropy, and ectropion are sometimes found. The common approach to preventing these conditions is through certification of unaffected breeding stock by the Canine Eye Registry Foundation (CERF).
