x 1000 on american bull dog they are very smart loyal and strong. no one comes through our door when ours is in charge. he is on the small side only about 90# but its pure muscle and stopping power with out the hip displasia of shepperds. he only likes dogs he is comfortable with. i had to socialize him alot to get people safe but only around people he knew strangers are out as far as he is concerned. i have a 7 and 1 year old daughters and they climb all over him and pull on his ears to no end he has never once so much a growled, he walks to the door when he is done playing. i have the scotts type but i have seen great results from both. they need excersize. good luck.
