I am looking for a good trainer to work with my 12 week old Alaskan malamute puppy. He is so behaved but showing signs of dominance with our 15 year old malamute. seems to have toy food and maybe crate "aggression". He will growl when the older dog goes by if he has a toy. (She's deaf so probably not putting him in his place. Also doesn't really want to deal with him). I want this to end immediately! I'd like to be able to have him share everything and be a good boy with other dogs. He seems behaved around other dogs so far but I'm worried if one came over into our home that he'd be possessive of "his" things. Help!
