Thing is being a cross he will be unique and his littermates may havew been quite differenet inheriting different traits from the parent breeds perhaps the worst traits of both breeds.
Nothing against crossbreeds that happen by accident, but definately agains their deliberate breeding from sub standard purebrees (else why would they not breed a good litter to keep the standard of the parent breed?
Breeding from dogs that are not the best examples of their breed and had all relevant health tests is irresponsible. The reason many of these puppy farmers/millers do it is because they have poor purebred stock, so with first generation crosses they are banking of the faults not coming together which they surely would with their purebred specimins (but they sure would come out once they bred from the pups themselves, and the problems from both breeds).
Also it means they only need one stud dog to mate to all the different breed bitches.
So by all means rescue one of these often ompulse bought and soon cast off pups/dogs from a shelter, but do not line the pockets of disreputable money grabbing puppy exploiters.
