Such as if we have a family or personal emergency. I guess a frequent friend or family member could be accepted as a food provider?
The handler has to tell the dog to "leave it". TDI really emphasizes that command and handler vigilance in general (versus something like French Ring, where a stranger is literally throwing food at a dog with the handler out of sight, and must ignore it). Not really sure what the OP has in mind.TDI dogs require refusing treats from strangers, just saying.
TDI food refusal is nothing like real food refusal/avoidance training. In TDI, you call your dog off food if you notice the dog paying interest - handler is always around during therapy visits. In advanced training for things like KNPV or true food refusal when owner is out of sight, it requires far more stringent and advanced training. There are many issues that may arise with this training if done improperly....so like I said, start slow and work on socialization, bonding, foundation work....TDI dogs require refusing treats from strangers, just saying.
