You know I have kept schtum up to now out of respect for the people on here who are into their pedigree pooches.
I'm pulling my punches even so, but I really do have to take issue with the idea that crossbreed or mongrel dogs are bound to be unhealthy.
Veterinary Medicine and Genetics both would have it that crossing two breeds would give you the ultimate healthy pooch, the F1 hybrid, good for hybrid vigour. According to my vet when I was researching options for a friend, it is rare to get the same kind of inherited problems in first cross animals that are found in the parent's breeds - although he did say it would make sense to not cross a breed which, for instance, has a high incidence of hip dysplasia with another which also has a high incidence of the same problem.
I absolutely applaud all the registered breeders who take a great deal of care to ensure that the pedigree dogs they breed and sell have as low an incidence of their breed's particular problems as is possible - but the point is, these tests and so on are less necessary, even unnecessary, when the animals being bred from are not pedigrees and do not have that in their genetic makeup which comes from generations of selecting on an often narrow range of specific characteristics.
I have had and have known well pedigree pooches, crossbreds and mongrels, dogs from working and field champion strains and some from show strains, rescues and waifs, surplus farm collies - you name it. All have been lovely dogs, some have had problems, some with health and a few with temperament. For the most part, the crosses and mongrels have had less problems and lived longer than pedigrees of the same body type. A vet once told me that the usual 'one human year equates to seven dog years' applies to large pedigree dogs, that with mongrels and some smaller breeds it is more like one for five.
Me, I like to live and let live. If some people prefer pedigrees, that's fine with me. But I don't like being preached at and I will stand up for any underdog. Some of the very best dogs I have known have been crossbreeds and mongrels, several of them rescues. I have no issue with someone breeding a litter of nice family pet dogs from known but unregistered parents and taking care to make sure the pups go to good homes. I do dislike breeding for pure profit, whether it's pedigrees, 'designer crossbreeds' or bitzers.
