We arent sure. We got him from a vet who had found a bunch of staffy x puppies dumped in a big garbage bin.
The vet seems to think its natural and that he may have some stumpy tail cattle dog in him. It does seem quite natural.
The vet also said he had a theory as to what had happened to him. He was in pretty bad shape eg; holes through his lips like he had had scewers stuck through them or something and much more. And he was terrified of people so he believes he was bred for fighting and all the injuries were them trying to get him angry. And he was only 7 weeks old
he says either they docked the tail or the stumpy tail cattle dog was bred into them so the tails were already 'docked'. He doesnt really think its likely that it was docked unnaturally as there are no signs of that having been done.
