More Dog Problems

The chiwawa mix is in heat. This is my first time seeing a dog in heat (most people I know have mutts that have been neutered/spayed) and it is not fun. She climbs into my lap and humps my arm. She bleed on a white dress I was wearing (this is actually how I learned she was in heat). She goes outside to the front yard and stands next to the rott so he can sniff/lick her. We are now keeping her away from the rott because if he tries to mount her, it will not be pretty.
