The condition page — knees

The both-knees rule: what it actually says, and where it stops.

The story travels in every dog forum: "my dog tore one ACL, and the insurer denied the other knee as bilateral." Sometimes that denial is the form working exactly as written. Sometimes the story leaves out the one fact that decides everything: when the first knee problem began — before the policy, or during it. Every bilateral rule we read in the binding forms looks back to problems from before coverage or a waiting period. No form bars a claim because a knee tore while covered and the other knee tore later.

The rule, carrier by carrier

CarrierBilateral knee rule (from the forms)
ASPCA family (Spot, Pumpkin, ASPCA, Hartville, Wagmo)Any knee/ligament problem before coverage or in a waiting period → both knees excluded for the life of the policy. Never takes the 180-day cure pathway.
AKCKnee-wide in the newest form — but the rule lapses after 365 days of continuous coverage, alongside the pre-existing pathway. Absent entirely in the Florida form's missing provision.
EmbraceOrthopedic conditions are carved out of the cure pathway — a pre-existing knee is not reconsidered after any wait.
Trupanion · OdieNo cure pathway for anything; a pre-existing knee is excluded for the life of the policy like everything else.
NationwideSeparate mechanism: a 12-month cruciate waiting period on applicable plans, not waivable — a date problem even for knees with no history at all.

Checked Oct 20, 2026, from binding-form language. Full table: carrier rules.

The two cases that decide everything

Case A — first problem BEFORE the policy

Your dog strained a ligament in March 2023, treated and quiet ever since. You enroll in an ASPCA-family plan in 2026. In 2027 the other knee tears. Under the family form: excluded — both knees, for life, because a knee/ligament problem occurred before coverage. The 180-day clock never applies to knees. This is the case the rule was written for, and an appeal rarely moves it. Your real options are computational: at AKC the same history becomes coverable after 365 days of continuous coverage (non-Florida); the checker shows it per condition.

Case B — first tear WHILE covered

Your dog tears the left cruciate in year two of a policy, the claim pays, and the right cruciate tears in year three. No binding form we read bars the second claim because of the first — the bilateral lookback reaches back to before coverage, and Case B's first problem is inside it. If a carrier denies Case B citing bilaterality, that denial deserves the full first-steps treatment and, if it holds, the state complaint door: the 51 doors.

Which side, which date — the entries the checker needs

For knees, the checker asks which side and the last symptom/treatment date, and whether the problem started while your current policy covered your pet. That last answer is the Case A / Case B switch: mark it honestly, because the computation (and any real claim) turns on it. Cruciate surgery commonly runs into the thousands per knee — the stakes on this one rule are the highest in the dataset.

Run your own pet's dates. The free Switch-Check takes your pet's conditions and their last symptom/treatment dates — and returns the per-carrier verdicts, the re-open dates, your earliest safe switch date, and the stay-or-switch math. Run the Switch-Check →

Included in the $39 PetCoverCheck Playbook

  • The per-carrier switch worksheets: for every carrier whose form we have read — its cure rule, its knee rule, its waiting periods, and the exact questions to get answered in writing before you switch (and the answers that mean stop)
  • The cure-window date planner: the fillable planner that turns your pet's history into dates — each condition, its last symptom/treatment date, each carrier's window, the re-open date, and your earliest safe switch date — with worked examples (the 180-day ear infection; the 365-day discretionary case)
  • The renewal-hike response: the downgrade levers that lower your price WITHOUT resetting your clocks — a higher deductible, a lower annual limit, a lower pay-out percentage — and the levers that secretly start a brand-new policy and restart every exclusion
  • The dropped-by-Nationwide re-enrollment guide: the order of moves for non-renewed owners — which conditions became pre-existing the day coverage lapsed, which pathways can still reach them (including the 365-day continuous-coverage pathway and its Florida hole), and what to get in writing
  • The claim-evidence log: the dated record structure that decides claims — symptom dates, treatment dates, which side/joint, invoices, and the records to request from every vet who has ever seen your pet — built before you need it, not after a denial
  • The denial first-steps chapter (a chapter, not the product): how to read the denial letter against the form section it cites, your carrier's own appeal window (14 to 180 days depending on the carrier — the table is inside), the records to gather, and your state insurance department's complaint door
  • The switch execution sequence: the exact safe order — written confirmation first, the new policy bound second, the old policy cancelled last — plus how waiting periods overlap and the records-transfer checklist
