after an incident can you be evicted?

o.k. we are renting to own from my father, on christmas morning we were watching my sisters dog “who lives with him” and the dog bit my husband making him go to the hospital for infection and a tetnis shot. My father finds out about the bite and get’s mad at us and tell us to get out of HIS house and says he’s going to have us put in prison “nonsense” and have our children taken from us, Yes this really stemmed from a dog bite. So now he’s served us with an eviction notice and to me it seems stupid because we’re paying his mortgage payment to the lady he’s financing this place through and we have homeowners insurance on the place that he wanted us to carry on the house because WE were buying it from him. So this just baffles me because it doesn’t seem legal because it’s a form of retaliation??????? please help cause I’m looking into getting a good lawyer
just so you know we didn’t harm the dog what so ever
also we have tried to finance but he kept telling us to wait on it, also we stay because everything we have has gone into this house in remodeling it, not to mention the labor, why should we have done it all for free if he was never gonna sell it to us?
