ideas on tenant pet liability insurance for pitbulls?

[Alan Brown]

She's a pretty great tenant other than the fact that she didn't disclose she had a dog.  NOt only a dog but a Pitbull, who is on my insurance co's list of dogs they won't insure.  

She's also 6 months pregnant (the tenant) and I don't want her to move.  The dog is SUPER sweet, of course, but i cannot take a chance on something happening with the dog.  

Looking for some kind of liability insurance she can obtain that will cover us from any twists, keeping in mind that if a child got bit in the face, even accidentally by a confused dog, the lifetime cost a jury might award would be in the millions, I'm sure.

Any Ideas?

I also have not been requiring tenant insurance, more particularly pet insurance-- could that be a game changer?  My manager has been charging a $250 flat non refundable pet fee, which seems sort of useless, in fact may even make a tenant feel like they've "paid in advance for any damage, so why be astute about animal's behavior?"  Wouldn't it be better to just require them to pay for insurance to cover cat pee in carpet?  How the ins company determines whether the current pet is at fault, I don't know.
