If you have a Pitbull, any insurance will be difficult to get if at all. Pitbulls are number one on the list of dogs likely to bite people. It does not matter that there are several different breeds of pit bulls many of which are the gentlest of dogs.
Other high risk dogs include Malamutes, Akitas, Chows, Rottweilers, Shepards, and Doberman pinschers (the biggest goober dogs you will ever meet).
Big dogs can't catch a break which is one of the reasons Apt. Complexes often only allow dogs under 20-30lbs. This is ironic as a lot of smaller dogs (as a breed) can be biters, notably cocker spaniels. Of course, smaller bite usually means less injury.
I worked with animals for almost 20 years, and I've seen good and bad dogs in all breeds. Owners sometimes allow dominant dogs to be the alpha in the family - not good. Training is really important, but even if you do everything right you are still punished for the breed of dog you have.
I had a Rottweiler. You would never break into the house, but once you were let in, she just wanted to slime you with her tennis ball. But I've seen rotties I wouldn't look at sideways. It's a tough topic all the way around.
Good luck with your efforts.
