i don't care whether a dog is show quality or not, that doesn't matter to someone who wants a dog only as a companion animal.
however, even in a pet dog it matters that the dog is healthy and free of genetic disorders like liver shunt, collapsing trachea, cushing's disease, legg-calve-perthes disease, luxating patellas, hypoglycemia, hemorrhagic gastric enteritis, retinal dysplasia, progressive retinal atrophy and so on and so forth.
responsible breeders test for these disorders and eliminate them fromt heir breeding program as much as possible. since you continue to evade questions on the topic of health issues, i can only assume that you don't have a clue if your dog and the female you bred him to possibly pass on any number of these in their offspring.
my friend's dog that died suffered from a collapsing trachea, luxating patellas and severe allergies, so she isn't going to take the risk of buying a puppy from unproven stock ever again. i can't say i blame her, because int he six short years her poor little dog lived, she spent thousands of dollars in vet costs to have all the problems diagnosed and treated.
you are a prime example of a back yard breeder who is bringing puppies in this world for no good reason at all.
