Well I haven't had this problem with a dog, but I have with a cat. A few times we would be at her house and when she would ask me to stay over I would say, I have to go home or my cats will get sad. Boy was she mad about that one. And because she's allergic she can't stay over here. So once she finally realized I want to be at home with my cats so they don't get lonely she started taking allergy shots
