Hi, Iposted a thread ystday about my 8wk old yorkie growling when he's being brushed and one of you guys asked if he growled at any other time, thinking about it the answer is yes! when he plays with my daughters 8 month old yorkie cross (always supervised) he growls and snaps if the older dog gets a bit boisterous, is this normal? i'm new to this puppy business and i thought it would be the older pup that was more dominant but its the 3 inch terror that seems to be the boss, have i got a delinquent dog ? he's literally 3 inches high. Lisa.
