My dog has recently started getting scared of my boyfriend when he enters my house. She used to love him she would always want to cuddle with him, he comes over my house almost every day and now when he tries to greet her she hides from him. He feels awful about and he has never done anything that harmed her. What made her scared of him all of a sudden?
I heard dogs can sense cancer. I don't want to alarm you but I would look into it. Get checked. Hope for the best. Good luck .
