Im 4 months pregnant...

And I can't stand my husbands dog. 
He prefers the dog over me. 
A week ago he told me to reschedule my ultrasound appointment so we could take his dog to the vet first. 
Today his dog popped inside the apartment and I threw up. He didn't seem to care.
There's more to it than just what I described. I just don't want to get into it. What should I do? He doesn't want to regime the dog or anything.
