that does not sound like a border collie at all! 55 lbs is huge for a BC any bigger and there is no way its pure ya I wasent sure, but not all barbie collies look like that picture thats just the first pic I found, basicly a barbie collie has long fluffy hair, is husky, and a short muzzle and basicly looks like an aussie with a tail oh and yes dogs in canada can regiter with AKC, happys parents are registered, well her dad is, but thats cuz her dad is from the states a breeder of barbies collies, alothough he is not one himself, his parents were bought for working only there are long coat border collies but its never fluffy
