I was hoping you could help me with this question. I have a friend who has a 3 year old dog that has been acting weird for the last few months. The thing is she is pregnant and this behaviour started around that time. Lately he is peeing and pooping all over her house, destroying all his toys and now he is running and hiding from her. Normally he is her shadow. When he is around he will ot allow anyone near her. I was hoping you can help. Is this normal behaviour?
