Most commonly, when we’re looking for who we can recover against for dog bite injuries, it’s the homeowner’s insurance of the dog owner. If the homeowner lied on their policy about the kind of dog they had or whether they had a dog at all, that can complicate the matter, but most commonly people are truthful about their dog ownership and their homeowner’s insurance covers the actions of the dog.
In the case of a renter whose dog injured someone, we may consider an action against a landlord if there had been previous complaints about the dangerous dog that the landlord chose not to address.
For example, if several people in the building had been complaining about the dog and the landlord ignored them, that would be a possible cause of action. Or if the landlord tolerated tenants having dogs in violation of a policy, an action against the landlord may be possible but would be challenging.
