The most effective way to use treats is to reinforce a calm, submissive state. Never use treats to reward an excited, over-stimulated state of mind. Always let your pet smell the treat first but hold it up away from them and wait. Remember pets, especially dogs, can smell from over 5 metres plus away so you don’t have to put the treat under their nose.
Once they have the scent, dogs may initially jump around, and even jump on you. If this happens, indicate that you don’t approve with your attitude and body language, your patience as an owner will pay off in a well-behaved pet. They will figure out that the cool calm approach delivers results, sitting and waiting while looking at you in quiet anticipation. At the moment of calm, give them the treat. Don’t use treats to reinforce an excited pet, but rather to command the calm, submissive state.
