Dog Health Questions: Male Dog becoming agressive now that I am pregnant! Advice?

I am 8 months pregnant and have a Male dog. He is neautered but since I have become pregnant he went from the Calm submissive love muffin loving everyone to being overprotective of me to the point where he would nip. He really hates males except my husband..I just don't get it. We have spent hundreds of dollars on Dog training from Bark Busters training to Dog therpy and nothing has worked. Our Vet says you can't Untrain "Instinct" since our dog instict is to protect pregnant females.

However it's not just with my dogs. My Husbands best friend has a male dog who is wonderful but since I have gotten pregnant he is even protective of me and I hardly see him..Also when I go to a dog park all the dogs sworm at me like I am a female in heat...This is getting very annoying...Any tips or advice?

I havent heard of this, the only thing I can think of, is that you are ommitting alot of hormones. I would be very concerned about your dog being around your new baby.
