(a) A purchaser is entitled to a remedy from a seller pursuant to this section if after the purchase of a dog from such seller, 1 of the following subdivisions becomes applicable.
(1) Within 20 days after purchase of the animal, a licensed veterinarian states in writing that the animal suffers or has died from an illness, disease or other defect adversely affecting the animal's health that existed in the animal on or before delivery to the purchaser. Intestinal or external parasites shall not be considered to adversely affect an animal's health unless their presence makes the animal clinically ill.
(2) Within 2 years after purchase of the animal, a licensed veterinarian states in writing that the animal possesses or has died from a congenital or hereditary condition adversely affecting the health of the animal or that requires hospitalization or nonelective surgical procedures.
(b) A purchaser entitled to a remedy pursuant to this section may elect only 1 of the following remedies:
(1) Return the animal to the seller for a full refund of the purchase price and reimbursement for reasonable veterinary fees for diagnosis and treatment in an amount not to exceed the original purchase price of the animal.
(2) Exchange the animal for another one of purchaser's choice having comparable value, providing such replacement animal is available, and receive reimbursement for reasonable veterinary fees for diagnosis and treatment in an amount not to exceed the original purchase price of the animal; or
(3) Retain the animal and receive reimbursement for reasonable veterinary fees for diagnosis and treatment in an amount not to exceed the original purchase price of the animal.
(c) For purposes of this section, the veterinary fees shall be deemed reasonable if the services rendered are appropriate for the diagnosis and treatment of the illness or congenital or hereditary condition made by the veterinarian and the cost of such services is comparable to that charged for similar services by other licensed veterinarians in proximity to the treating veterinarian. A veterinary fee shall be presumed reasonable in the absence of evidence to the contrary.
(d) Refunds and payment of reimbursable expenses pursuant to this section shall be made by the seller to the purchaser not later than 10 business days following receipt of the veterinarian's statement required by § 4006 of this title, except in cases in which the entitlement to a remedy is contested pursuant to § 4008 of this title.
