I absolutely judge people who rehome dogs. Sorry, but I fled serious domestic violence with a toddler, became extremely ill and ended up disabled in a wheelchair with very high needs disabilities, and have had to move house a number of times. Never once would I have dreamed of palming my dogs off.
Most people rehome dogs because they're either thick, entitled, or both. They don't research, they go on the first website they find with puppies for sale, pick something close to home and from a puppy farmer, then are done with it in a few weeks when it gets too much. Then, because they didn't get it from a reputable breeder, there's no return to breeder contract, so they just get shot of it. It is absolutely foul, and really, really makes me angry.
Then there are the entitled ones who want a dog NOW and they feel as though they should be given a dog from anyone, including reputable breeders who ask them questions and deem them unsuitable. Then they go and get aforementioned puppy farmed dog because that's all someone will sell them
If people only bought puppies from reputable breeders, there would be NO dogs in rescue. None. Zero. Imagine that. All reputable breeders take dogs back at any stage in their life.
But, people won't use reputable breeders. They're not willing to wait, they're not willing to travel, they don't meet the breeders requirements (haven't done any research, wrong breed for lifestyle etc), they want to breed in the future. Entitlement, uneducated, impatience and unintelligence, always.
