Hmmm.. My dogs are not hyper at all. They are actually real couch potatoes. Infact when people come over to my home they are amazed how calm they are.

Also I have been researching about the theory of mutt/mixed breeds vs purebreds and this came up over and over again that mixed breeds can actually get genetics problems from both breeds they come from. And unfortunetly many unsuspected owners thinking a mixed is better do not get their dogs tested to be sure and could be carring a problem that just not has arised yet or can be passed on to their pups.

(e.g.: However, such a return to the wild is not going to happen, and in spite of assertions that they are healthier than purebreds, crossbred and mixed breed dogs are subject to the same diseases, structural problems, joint dysplasias, allergies, and genetic abnormalities as their blue-blooded cousins. Furthermore, it is more difficult to track diseases in crossbreeds and mixed breeds because these dogs are unlikely to be x-rayed for dysplasia, checked for abnormal thyroid or eye diseases, examined for heart problems, or tested for various autoimmune problems. For example, Golden Retriever-Collie crossbred puppies are susceptible to the diseases that affect the two breeds: hip dysplasia, heart abnormalities, eye problems, etc. The inheritance of structural problems such as hip dysplasia is complex and can multiply through the generations; thus mixed breed puppies in litters from crossbred or mixed breed parents are also potential victims.
