This is a Purebred "Blue Shar Pei" not an American Bulldog. They just didn't have Shar Pei's on their list. She is 18 months old, all her shots are up to date. Weighs 35lbs. Yes, that is correct, 35 lbs 18 months old. Part of me thinks she may have been mixed somewhere along the line with something smaller but I have not gotten her DNA tested yet. This girl is 18 months old, super friendly with kids and people, she is a great defensive/security dog as she likes to act tough and is very alert but wouldn't actually hurt anyone unless her owner was being attacked. I've been training her to bark 2 or 3 times and stop if someone is at my door. But her name is Riley for a reason. She doesn't take much at all to get Riled up, simply bounce up and down a couple times and she will start running circles around you! She likes dogs her size and bigger, not so much smaller dogs, she needs some personalized training on that.
