I wish people would stop breeding animals.....so many are killed because of it.
I think what you mean, if you would think about it, is that you wish people would stop indiscriminately breeding animals. First of all and especially the puppy mills, the bulk breeders for profit. But second, the "backyard breeders" who don't know what they're doing. And on that I agree with you one hundred percent.
I used to breed and show Siamese cats back in the 70s and 80s. My cats were very highly bred and much in demand - I had a waiting list and I interviewed everyone who wanted one of my kittens. The sale agreement had a buy-back clause - if they ever needed to get rid of the kitten for any reason, I would take it back. (I never had one come back and I kept in touch with all the owners.)
Same thing with dogs. I wish I hadn't spayed my girl, but it was the responsible thing to do at the time as a new dog owner who wasn't planning to breed. But we got into performance events and she is multiple-titled in agility and has her first hunting retriever title. On top of that, she is royally bred on both sides, with 2 Am/Can conformation champions and one Am champion on one side and multiple FC/AFC field trial dogs on the other. So as long as I bred her to a well-bred and titled dog (and, sadly, I have two in mind who would have been perfect 'nicks') I not only could have named my price, I would have a waiting list.
The problem is not with the well bred performance dogs.
