Week 2 Attention to Name

 STEP 1:  Your puppy should be on their 6' lead and a collar.

STEP 2:   Be sure you are prepared with  kibble in your hand  BEFORE giving a command.
STEP 3:  Say your puppy's name.
STEP 4A:   Immediately upon your dog looking into your face (and not glancing immediately away), say your release word "yes" and deliver the food reward as you release them.
STEP 4B:   If they do not look to you, first try calling their name again.   Give them 10 seconds in between so you aren't just rapidly firing off their name.   If they are just really enamored of something other than you, you could try to gently tug on their leash and see if they will turn.   You could also try to make a silly noise after you say their name.   Usually though, once they know what the deal is with the food reward, it does not take more than three times to get them to look at you.
STEP 5:  Repeat from step 2.

As you advance, you can start holding the food reward away from you, and train the dog to look at you instead of the treat.   Just time it well so the food gets to the dog with the release word "yes" immediately after the desired eye contact is met.
