Hey, sign a contract, follow it. Not too hard to figure out. If you can't follow the rules of adoption, then don't get your dog from that particular place.
I have 1 Great Dane from a rescue. I had to follow their rules to a "T", until the lady running the place went dilusional, tried to extort $2,000 from me, and I threatened legal action...less than a year later the agency no longer existed, and my contract is now null and void. But the rules weren't all that hard to follow, and honestly, I'm still doing everything except sending her a copy of annual shot records, since there's no agency to send them to anymore.
