Why teach "WATCH"?
Because getting your dog’s focus with a single word is very useful. You can distract him from trash in the street or keep his eyes on you when walking past another dog. Plus, dogs that are rewarded for paying attention do it more. And attentive dogs are easier to train.
How to teach it
Step 1. Grab a bunch of small, delicious treats and face your dog—he can be sitting or standing.
