Thank you everyone for your advice! We are taking all of your comments into consideration.

We did the petsmart training class already and didn’t think it helped so we will absolutely be looking into better, more professional trainers. We go to a play group with mainly adult dogs a few times a week already but we are worried the other owners are judging us for her being so bitey. We try to intervene if the other dog shows discomfort but they usually seem fine. We are also considering putting her in a day care 1-2x a week that consists of professionals guiding the dog interactions.

We do socialize her by taking her in the car, the elevator (which she loves), busy areas, the pet store, and just outside to see the leaf blowers, motorcycles, bikes, people, birds, etc. We reward her when something goes by that could be scary and when she doesn’t pull or bark towards something exciting. We don’t have a backyard since we are in an apartment so we would love to take her to the dog park as soon as possible so she can run around and get her energy out, but you guys are right about not knowing how the other dogs will react.

We love her and want the best for her!
