Hello, a couple months ago my home became a multi-dog household, with the newest addition being a now 10 month old GS/lab mix, and our resident dog, a 3 year old beagle/rottie mix, both males. They are both very well behaved and have never fought. However, they were not socialized properly as puppies—or at least we did not adequately socialize our beagle mix when he was a puppy, and GS mix was already 6 months old when we got him and we don’t know if or how his previous owners socialized him.

The results of their poor socialization: resident dog does not seem to recognize playful behavior from new dog and thus becomes uncomfortable, clearly cares for new dog (acts to protect new dog if anyone is playing rough with him) but won’t play with new dog, and seems to sometimes even avoid new dog.

New dog is a little better with socialization, but his main fault is that it seems he doesn’t know how to recognize resident dog’s “corrections” to him and to back off (even if most of the time he simply wants to play with resident dog), and he also has some bullying tendencies, some intentional and others not (wants to play with whoever resident dog is playing with, sometimes bugs resident dog to move if new dog wants to lay down in that spot, etc; though never has shown any physical aggression).

Resident dog is, personally, my dog, and I love him dearly, though I love new dog too, and would love to see them bond and play together, only I don’t know the best course of action to achieve that.

I would greatly appreciate any help with ideas on how to adjust these behaviors of theirs, as well as weigh in on the idea of setting up a doggie-play-date with a friend (with a stable and model dog, of course) so that maybe visitor dog can teach them how they should behave.
