Hi! My cute little boy, Carter is a 2 year old Blenheim. He is a delight (our first Cavalier and we love the breed)!! He loves all people - often too much we work constantly on "down" This is my dilemna, my daughter just got a puppy, cross between a lab and something a cute and lovable puppy (the pup is 3 1/2 months and is the size of our boy Carter). When they come to visit Carter reacts in one of two ways.....he cowers away OR he has started growling and attacking the pup. At first we thought the aggression was a good thing as it is teaching the pup that he is at Carter's house and he needs to not jump (he is playing like all puppies do) on Carter and give him some respect. I am now not sure that the aggression is a good thing? How do we teach the pup to not be so excitable AND teach Carter that it is ok to stick up for himself, but he can't be TOO aggressive??? HELP!!
