Hoplikeabunny If you can't find a rescue dog that meets your needs, then a real dog lover would just not have a dog rather than keeping breeders in business.- That is absolute rubbish! You could apply that to anything! You could argue that someone who really loves children wouldn't have their own, as there are so many who need adopting around the world. I can guarantee that I absolutely do love dogs, you do not know me, and you cannot prove otherwise. I have known plenty of vets and veterinary nurses over the years, and most of them have had puppies from breeders, can you honestly tell me that someone who dedicates their career to helping animals doesn't like dogs?! Right....
I think a valid point can be made that people who love children, unlike the majority who love just their own children and other children they have a relationship with, would indeed look to adopting from children who already exist, rather than creating new ones.
Having children is a selfish act which isn't done because people love children. Having some concern for, and liking to interact with, children or dogs does not constitute love. True love involves sacrifice, it's not about what you want first and foremost. I'm sure your vets and veterinary nurses do like dogs but if they go for puppies that's their selfish human nature showing through and it does not demonstrate love.
(I'm at least as selfish as the next person, but I don't think as highly of myself as other people like to think of themselves.)
