Most breeder contracts contain a health guarantee, a return policy, and a limitation on the buyer’s remedies. In practice, those three clauses do most of the work when a puppy develops a congenital condition, a genetic defect, or an illness that predates the sale.

A growing number of states have enacted so-called ‘pet lemon laws’ that give consumers rights independent of the contract — typically a right to a refund, a replacement, or reimbursement of veterinary expenses when a covered condition is diagnosed within a defined window. These statutes do not preempt the contract, but they set a floor that no breeder can waive.

When a dispute arises, the practical question is rarely who is ‘right’ in the abstract — it is what a neutral investigator will find in the medical records, the contract, and the correspondence between the parties. Arbitration and mediation allow that question to be answered quickly, privately, and without exposing either party to the cost and publicity of a lawsuit.
