How to judge a seller's trained protection dog claims

1. A live or in-person demonstration of obedience around distractions.
2. A written account of what the dog has been taught and by whom.
3. Health records and who performed any testing.
4. A reference you can call.
5. A contract that explains returns.

Ask the handler to call the dog off something interesting. A dog that releases and returns is more useful than one that only performs on cue in a quiet field.

Pressure to wire money, no chance to meet the dog and guarantees that it will never bite are reasons to stop. State law places responsibility on the owner no matter what the seller said.
