Please show me where I said that someone that spends ANY amount on a dog will take of of it?
Do you really believe that someone who can't afford to take care of a dogs medical needs should own one? I don't know what planet you are from, but a $1500 vet bill is not exactly excessive these days. I know people that have taken second mortgages to pay vet bills. Seriously. Do I think you need to have $20,000 on henad to own a dog? No. But if you can't afford $500 for the initial purchase or fee, than you probably don't have the financial ability to provide proper vet care. Flea and heartworm provential are considered 'expensive' by many pet owners for crying out loud.
Just becaue someone has good intentions and treats the dog like a tiny diety doesn't make them a good owner either. Gawd I'm so sick of casual, never train, never work, just a pet, yard full of poop / crap in other peoples yards - go to the offleash park and stand around chatting while their dog growls, mounts, engages in dangerous behavior "Gee how cute" - get a dog cuz it's 'cute' and never really do anything WITH it 'pet owners' I'm ready to vomit. And yes, that includes a whole laundry list of people with disposable income as well as those that can't afford it but do it anyway, but the list of people who spent money is much shorter, in part because they were screened by breeders in the first place rather than buying from a backyard.
The point was they are entitled to use whatever tools they feel are handy in reducing the chance the dog will come back / be abused / run away / etc etc.
Besides, aren't we talking about a high dollar dog to begin with here? Through a breed rescue, not a general neighborhood rescue? What, are breed rescues supposed to be the solution to the 'I'm too stingy to buy one' people? Good greif. Plenty of Labs and mixes at the county AC for much cheaper if you aren't wanting to drop $500 +/- for a particular breed.
