Final update: they agreed to keep the dog out of my bfs room(where ill be staying) and make sure he is locked in a room when no is home but me! Other than that i need to be careful around him
Update: im moving in with his family over the summer for an internship. I told my bf about my worries with the pitty and he brushed it off. With medical issues i cant live safely with a dog that jumps but since im a guest i cant ask them to train the pup
