P.O.
E.,
I don't think I can help you with the dog house (although, I would do a google search on two dog doghouse, there are several sites that sell dog houses... some are quite cute), but I can say that I have a little crawler (8mo) and two dogs and a cat. At first I was running all around trying to vacuum and use the wide sticky sheets, but my husband just kept telling me not to worry about it so much. I eventually gave in and yes, she has gotten covered in dog hair sometimes and face-planted right in a pillow of hair, but she seems none the worse for it. I've also read that children that are around animals during their first year are less prone to allergies, so I'm hoping this is helping her immune system. I guess we'll see.
Hope that helps.
