I have a 2.5 year old Alaskan Malamute. Lately he has started growling whenever he wants to play and during play. When I take him to the dog park and he tries to play with other dogs, he starts growling and a lot of times the other dog's owner thinks he's being aggressive, especially due to his size.
I'm wondering how I might train him to not growl when playing? I thought about telling him 'no' when he starts growling when I roughhouse with him, but I'm afraid he might interpret it as 'no playing.'
