The age of the pup is irrelevant to the question you asked, this could have happened after 12 weeks, 6 months, etc....

Anywho, never let a pup go without the prospective owners SIGNING a detailed contract that outlines the policies and procedures in events like these. No signature than they don't get a pup. Always protect yourself. Include a clause that says the dog must be brought back in the event that the vet finds a diagnosis (within the 3 days)to be re-examined by a vet you know and trust! If the pup does not see a vet in 3 days then they loose the right to a full refund and you can specify what illnesses you can guarantee against. Illnesses that fall outside those parameters are just the chance you take when buying an animal.

That pup could have gotten dropped, could have choked and gotten brain damage, etc. There are a million things that can cause a seizure and I believe this dog was euthanized prematurely, perhaps to mask something that happened that was their fault. Were xrays done? could the pup have been dropped?

Bottom line if no contract is signed than it is usually defaulted as an as-is purchase. Dogs are property and they would have to prove you sold them a sick dog on purpose to win anything and because the dog was destroyed, there was never any second opinion possible. You were really nice... You did not have to be and you may have been scammed.
