I am sad that people are being rude, it does negate the facts, and I hope I did not come across rude, i tried to come off as passionate and put that into how important the facts that presented are.

Do you really think that the millions of dogs produced every year by irresponsible breeders who end up dying in shelters are a result of pet owners who mistreat their animals? Yah some are. But the biggest problem out there are the people who think they have a great pet and want to see little offspring running around. Im glad the OP is good to his pets, maybe he can open his eyes to the huge overpopulation problem of dogs and realize that not breeding like he is, would be the kindest thing he can do for dogs.

Yep some purebreds have genetic problems. But do you really think that breeding mutts isnt passing off those same genetic traits? Just because it is a mixed breed doesnt mean it wont inherit some of the bad genetics of the breeds it is a mix of. This is also why it is very important for a breeder to test their dogs to weed out those genetic traits. Responsible breeders do this, but unfortunately the irresponsible breeders vastly outnumber responsible ones and so breeds are abound with these horrible problems

Breeding a dog back to back is pretty awful. It is extremely hard on their bodies.
