You are lucky Loki is soo stubborn haha I had to get him a prong collar for pulling and he's also a nipper...he's actually real good with kids and people he doesn't know while he's in that shy stage but it's been hard teaching him not to bite when he's playing...but D/A is the only thing he has a problem with. he is great with kids though he is ALWAYS supervised when he is around them. my worst nightmare is him gettin in a fight because of BSL. the only reason i still have mine is because we are not classified as a city where i am and everyone that had a pit before they banned them got to keep their pit. I GOT LUCKY!!!
