I just want to add... the whole statement of most of the dogs in shelters being strays, old, or sick, that is a HUGE misconception! People feel that there's an overpopulation mostly because of stray dogs, so so wrong. Although there are strays out there and they should be saved & rehomed, from working at the SPCA and seeing tons of litters come in, the vast majority of pups come from BYB's. I agree that litters should be bred responsibly, but it's so much more than that. Only dogs who have been proven to be a wonderful example of their breed in shows & work need be bred. Think of every person with a family dog breeding that dog. That equals an average of 5+ pups per family per year... which equals at least 4 of those pups on average will end up in a shelter, basically. And most will end up in a shelter between the age of 6 months - 2 years. Even if every person that breeds their pet dog gives them shots & vet check ups and such, there will still be a huge overpopulation. Which is why people need to stop seeing breeding as a fun side-project for money or something that should naturally be done, and start seeing it as something that needs to be left to those who dedicate their lives to showing, working & breeding.
