If your puppy is sick
New Hampshire law protects people who buy dogs, cats and ferrets from licensed sellers.
What you can ask for

Minimum age to sell a puppy

Federal Animal Welfare Act rules (9 C.F.R. § 2.130) bar licensed dealers from shipping puppies under 8 weeks old that are not weaned, in every state.
What to do if you bought a sick puppy
- Take the puppy to a veterinarian right away and ask for the diagnosis in writing, within 14 days of the sale.
- Tell the seller in writing, with a copy of the veterinarian's statement, and keep proof that you sent it.
- Choose what you want: a refund, an exchange or keeping the puppy with the vet costs paid, as far as the law allows.
- Keep everything: the contract, the ad, messages, receipts and vet records.
- If the seller refuses, contact the consumer protection office of the New Hampshire attorney general or file in small claims court.
