Does any one know where I can obtain "Renters Liability Insurance" on my 4 year old Pitbull?

I am being forced (by a stupid family member) to get some insurance in the next month if I am to continue to stay in the home I rent from them - due to fear that has been placed in their mind from their insurance broker.

Grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr - we have lived here for the last 4 years with out any insurance and with out a single problem from our big bad pitbull that runs from a Chihuahua that gets to close - so why now -

.... they are even forcing us to sign a lease after 4 years of being here - IF we are to reamin past November 1st - I HATE family at times -

.... they tried to raise our RENT $150 and we said HELL NO! - for that was not the original agreement.
