Most claims process smoothly. The ones that don't almost always fall into one of these categories — nearly all of which are avoidable if you know what to watch for going in.
Pre-Existing Conditions
The single biggest source of denials. If a symptom was documented — or even just mentioned in passing — in your vet records before your policy started or during the waiting period, it can be excluded permanently.
Avoid it: Enroll before any symptoms appear, and read exactly how your insurer defines "pre-existing" — some clear a condition after 12–18 symptom-free months, others never do for certain conditions like hip dysplasia or cruciate ligament issues.
Waiting Periods
Every policy has one — typically a couple weeks for accidents, sometimes longer for illnesses. Anything diagnosed during that window is treated as pre-existing, even if it's genuinely new.
Avoid it: Know your exact waiting period dates and avoid non-essential vet visits during that window if you can help it.
Bilateral Condition Exclusions
If your dog's left knee needed cruciate ligament surgery before you enrolled, some insurers will exclude the right knee too — on the logic that a condition affecting one side often affects the matching side eventually.
Avoid it: Ask specifically about bilateral condition policy before enrolling if your dog has any joint history at all.
Lapsed Routine Care
If a lack of check-ups or vaccinations is shown to be a direct factor in an illness or injury, some insurers will deny the related claim — this is less about punishing you and more about the policy only covering accidents and illness, not neglect.
Avoid it: Keep annual exams current even when nothing seems wrong; it protects your coverage, not just your dog's health.
Incomplete Medical Records or Documentation
Missing pages, unclear forms, or a spotty medical history — especially after switching vets or insurers — gives an adjuster room to push back or delay.
Avoid it: Keep a personal copy of your dog's full vet history, and request complete records whenever you switch vets.
Missed Filing Deadlines
Most insurers require claims submitted within a set window after treatment — commonly 90 to 180 days. Wait too long and the claim can be denied on timing alone, regardless of how legitimate it is.
Avoid it: File as soon as possible after any vet visit, even if you're still gathering paperwork.
