What Dog Breeds Are Considered Dangerous by Insurers?
Pit bulls, Rottweilers and German shepherds come up most, but each insurer sets its own list.

When the dog is the reason
If the letter named a specific breed, the insurer's underwriting guidelines treat that breed as a higher liability risk, usually based on bite claim data, not your dog's own behavior. Some insurers decline the breed outright. Others will cover the house but exclude liability for dog bites, or ask for proof the dog passed a temperament test. A few ask about weight or history of bites instead of breed at all. What applies to you depends on the insurer, not on a universal list, so check the letter for the exact reason given. If it is the breed, the workaround is usually a different insurer that does not restrict that breed, or a specific liability exclusion added to keep the rest of the policy intact. A mixed-breed dog is sometimes flagged too, based on appearance alone.
One insurer's breed restriction is not the next one's. Some carriers write the exact breed your dog is, with no exclusion and no higher premium for it, because they weigh bite claims differently or don't ask at all. Since the letter's reason is specific to this insurer, checking what others would offer the same house and the same dog is the only way to know if coverage without the exclusion is sitting right there.
What if the dog isn't the only reason
A non-renewal letter can list more than one reason, and the dog may be the one that stands out but not the only factor the insurer weighed. If the roof is older, the wiring hasn't been updated, or there have been other claims on the house, those sit alongside the breed on the underwriter's file even if the letter only spells out one of them clearly. Reading the letter closely for every reason given matters, because fixing the dog issue alone won't help if the roof is also driving the decision.
A temperament test or a certification from a group like the American Kennel Club's Canine Good Citizen program is something some insurers accept in place of a breed exclusion, though not all do. If an insurer is willing to work with documentation, this is usually raised directly rather than implied, so it is worth asking rather than assuming it is off the table. A dog with no bite history and a clean behavioral record is a different underwriting question than the breed alone, at least to the insurers who are willing to look at it that way.
Umbrella liability policies are a separate piece worth knowing about. These sit above a homeowners policy and can cover liability a standard policy excludes, including dog bite liability in some cases, though the underwriting on the umbrella policy itself may still ask about the dog. It is not a universal workaround, and whether it applies depends on how that specific umbrella policy is written, but it is a question worth raising with any insurer being considered.
If the dog moves out of the house, whether permanently or temporarily, that changes the underwriting picture entirely, since the liability exposure tied to the breed goes with it. This is not a suggestion, only a fact about how the restriction works. Some homeowners find that a renter's policy or a separate pet liability policy covers the dog specifically while the home policy stays clean. Whether that arrangement fits depends on the household, not on any insurer's list.
How insurers actually build these lists
Insurers that restrict breeds usually point to bite claim payouts, not temperament research or any ranking of which dogs are more aggressive. A breed shows up on a restricted list because claims tied to that breed cost insurers more over time, often because of the severity of injury rather than how often bites happen. That is a financial calculation, not a judgment about any individual dog, which is part of why the lists vary so much from one insurer to the next.
The breeds named most often, pit bulls, Rottweilers, German shepherds, Doberman pinschers, and a handful of others, tend to repeat across insurers because the claims data behind them is widely shared through industry bite statistics. But some insurers weigh that data differently, some only restrict a breed above a certain weight, and some have dropped breed-specific questions in favor of asking about bite history directly. A handful of states limit how insurers can use breed at all, so what shows up on a list in one state does not always carry over to another.
Mixed-breed dogs create a gray area insurers handle inconsistently. Since there is no registry confirming what breeds make up a mixed dog, some insurers go by the owner's description, some go by appearance, and some ask for a DNA test result if the dog's look raises a question. A dog that looks like a restricted breed can get flagged the same way a purebred would, even without documentation confirming the breed is actually in its background. This is worth asking about directly if a letter mentions breed and the dog in question is not a clear match to any single one.
None of this is static. Insurers update their underwriting guidelines as claims data shifts, and a breed restricted five years ago might not be today, or the reverse. The list that applied when a policy was first written is not guaranteed to be the one in place at renewal, which is part of why a letter can arrive even without a new dog in the house or any incident at all.
Before the deadline on that letter
Pull your declarations page and check whether the exclusion is for the house or just dog bite liability. Then see what your lender requires, since that's the minimum you need from a new policy.
