Dogs and pregnancy??

Elizabeth
I live with one of my relatives and my boyfriend and I have two dogs. One full pit and one half chihuahua half pit. Yesterday she figured out that I was pregnant. She told us that the dogs need to be chained up outside or gone down the road, she said because animals carry too many diseases. 
Personally I think she's going to cause me stress that's not needed, and I'm not even around them all the time. I go to school, come home, and they come in when it's time to go to bed.
I have my first prenatal exam Friday and I am asking my provider if there's any reason not to have a dog during a pregnancy. 😠😠
But I would just like to know what everyone thinks here.
