No man that is worth anything would ever make you chose between him and your furbaby... Thats just not right!!!! If he hates your dog, does he really love you???? I would say to him that we come hand in hand, and if he cant except the dog, BYE BYE... And yes do try to keep the dog in mind when leaving things out. Dog does not know any better. And your boyfriend does or at least he SHOULD. He sounds like a jealous, selfcentered kind of guy and in my book, he should have stayed with mommy.
Sorry this is so harsh, but Please find a new man, one that loves you and your dog.....
