So i'm looking to rescue a dog. And i've fallen for a 1 year old Staffy x Lab that needs rehoming through a private ad on Gumtree. The only problem is, the owners are saying they do not have the "verifaction of ownership" (as i worded it to them) paperwork. They say it's because the previous owners didn't have any. Where do i stand here? If they can't prove he is theirs. They could turn around and say he's been stolen after i pay them. Or he could already be stolen. Dodgy dealers as it were. I'm sure that isn't the case, but then it could be. Where does the law stand on this? They are telling me i just need to take him to the vet and they'll sort all that out. Shouldn't they be doing that? Taking him to the vet to get the paperwork. Is it their responsibilty to change his microchip to me as the owner before i get him? Or is it mine once i get the dog? I used to own a dog, but this was before microchipping was law, she was from a registered breeder as a pup to. I'm not clear on the rules of doing it this way. I live in the UK. Thanks.
