Re: Leave it
We've taught the "leave it" command in a similar fashion...dropping a treat on the floor and telling the dog leave it, with the praise and reward coming when they ignore what's on the floor and make eye contact with us. We'll then follow up with a "take it" command and give them a treat from our hands.
Once they've mastered the "leave it/take it" command at home, we take it out on the road. On walks, we'll toss a treat a few feet ahead of the dog and say "leave it"....we'll walk by, wait for the eye contact, then praise with "take it" and give them a treat.
After that, we'll work with diversions other than food - kids running, cats walking by, etc. Same drill...."leave it"....wait for eye contact and reward with "take it" and a treat.
