They are a great breed. Please make sure that the parents, grand parents and siblings to the parents of your puppy have been checked for mitral valve disease. This is a heart defect that is VERY prevalent in the breed. There is NO such thing as a line that does not have the problem. It is every where. So that you have a chance to be with your dog for YEARS AND YEARS to come...make sure that parents and relatives have been checked by a cardiologist several times throughout their life. The older the dog is and its still clear the better.
