When my min pin was in heat that is how she acted and i tell you it was the worst nights ever she would even come up to my face and paw at me and whine to wake me up she only did that for about 4-5 days though the rest of the time she was just humping everything in site
And it bites but there is nothing you can do
Well i guess there is you can do what i am going to do with my min pin and that is get her spayed if that is a option for you
