Local shelter gets a lot of restricted breeds because insurance will cancel if they have a Pit bull, Rottweiler, Doberman, etc.
We have had all of those breeds.. A couple Dobermans and one of them was the friendliest dog we ever had, The other was friendly but aloof. .. the Rotti was a sweetheart, super friendly. We have had 2 Weimariners and both were different. The current one had a bite issue and insurance canceled us. Next carrier went up 50% on our policy but excluded the dog from the policy.
