The Appenzeller is in excellent health. Apparently, the mountains and the corresponding climate have developed remarkable immunity in these dogs. They do not have such a surge in cancer as the Bernese Sennenhund, and their life expectancy is now quite high. The only hereditary ailment is hip dysplasia. Therefore, you need to carefully study the puppy’s pedigree. And during the growing-up period, carefully monitor that the puppy does not get injured, does not go down the stairs, does not jump, and does not run long distances.
