agressif behaviour towards new puppy
we recently bought a male bloodhound pup. Our 7 year old jack seems not to like him at all. He ignores him and when the pup approaches him he growls and sometimes attacks, even when the pup shows submission. he accepted the other dogs (females) we bought after a couple of weeks.
is he afraid he will loose his leadership? what do i need to do? i dont want to punish him all the time.
