Dog sellers might need to prove their animals are fit for purchase.

The House Economic Revitalization will vote Feb. 9 on a bill calling for Hawaii dog sellers to provide customers with medical records and a health certificate issued within 21 business days of the sale.

The proposal would require sellers to disclose any disease, illness or condition the dog has been afflicted with. 

They would also need a veterinarian to certify that the dog is apparently free of contagious disease and congenital and hereditary defects.

If a certificate from a veterinarian is not available, the seller could also provide a written guarantee that the dog is fit for sale. They would be required to provide a refund, exchange or reimbursement of medical costs if valid illnesses or defects are discovered.
