Using food in dog training is a no-brainer to most modern, motivational trainers. Dogs

are highly motivated by food (they’re predators, after all!), it’s easy to use food

lures to manipulate them into various positions, the dog generally enjoys the training

more so is more motivated to work, the human finds it easier so is more inclined to

persevere, and over time the association between food goodies and the owner becomes

very strong so the dog/owner relationship tends to improve. (Dogs like people who give

them treats. People often like other people who give them chocolate!)
