My boyfriend left his dog with his grandma and aunt’s family for a year. When he moved back I moved in with him. We live in the separated area. Every time I go in the house I say hello to him and I walk past him. When I’m trying to leave or talk to the grandma, he will charge at me, nip at me, and even grab my legs. He’s a miniature bulldog but he weighs more than me. I’ve been living here for 4 months and nothing has changed. I’ve never touched the dog because he doesn’t let me, and I give the dog treats just to be able to leave the house untouched. He even starts fights with the uncle. He will ask to shake hands with him just to growl and lunge at him. I’m assuming that the dog is possessive over my boyfriend and the grandma, but it’s been 4 months and I have to tiptoe into the house.
