Hi, My name is Joey I am in the navy and currently deployed, i have 2 dogs. An english bulldog named Geogia and a lab/hound mix named Jersey.(im from GA and my wife is from Jersey) Georgia knows speak, roll over, shake,were working on crawl, and if were outside off leash and i say home she will run to the back door. we got jersey right before i deployed so i havent gotten a chance to work with her yet. i had a friend that had a dog that could "smile" on command. which was really just showing the teeth but i thought it was neat any one got any tips on how to teach something like that when your dog almost never does that on her own???
