Rescue pup behaves aggressively
My family adopted a rescue pup from a shelter last week. They claim she is 12 weeks old, so 13 now, I guess. She's a total sweetheart with people - very comfortable being handled, snuggly, etc. But she behaves in a manner that seems super dominant and aggressive with my resident dog. She has never once shown any puppy submissiveness and growls and bites menacingly at my dog. She tries to climb on top of my dog while behaving this way. I thought perhaps it was fear aggression so I leashed my dog and made her do a down stay while the puppy roamed about and played and still the puppy would rush across the room and growl and bite at my dog. Today she did it to me when we were outside and she decided that she wanted to play tug-of-war with her leash. I calmly said No and then Leave It and tried to remove the leash from her mouth and she snarled and growled at me in not even a remotely playful way.
So here's what I know about her. The shelter labeled her as a lab mix - but at 12 weeks old she was only 11.5 pounds - so if she's a lab mix, the mix part was small. Or, she's younger than 12 weeks. I'm pretty sure she was taken away from her mother too early. She's from an unwanted litter in FL that was shipped up to a shelter in MA. She tries to find nipples on adult dogs to nurse from.
Anyway, I'm waiting to hear back from a local dog trainer for help in this situation, but in the meantime I'm at a loss. Any suggestions for reading material, approaches to this problem, etc would be most welcome. I feel like the sooner I start to correct this appropriately the better chance for success I have.
