my boyfriend and i are moving in together next month - he has a 6 y/o lab/boxer/pit mix (J) and i have a puppy poodle (S). they met at J’s house and it went okay - J was very excited/got the zoomies, but S is still shy around bigger dogs. eventually they fell asleep near each other. J has dog friends and has been fine sharing toys/water bowls. also, my old dog snapped at J while she was on J’s bed (lol) and J ran away and slept elsewhere. but i’m worried because J has gotten into quarrels at the dog park twice. both times, dog was humping her/cornering her to hump her and she gave them about 5 seconds and then snapped at them, but didn’t bite (we stopped bringing her to the dog park because we couldn’t avoid dogs who hump). she also once snapped at a dog when we were jogging with her on leash and an off leash dog ran up to her from behind. now every time J and S are together im visibly terrified J will snap at S and i’m dreading the 4 of us living together. we wouldn’t leave them alone together, S will be in a playpen in the bedroom and J will have the other rooms to herself. but does J seem dog aggressive based on those incidents/does it sound like a bad idea for them to live together?
