Associate the Name with Obedience & Food Rewards
I’ve been perusing the available dogs at various shelters and found a gorgeous white shepherd, but his name doesn’t suit the quite regal fellow he is. How difficult is it to change a dog’s name?
Not hard at all if you pick a name that sounds like dog food hitting the bottom of a bowl. Start on day one teaching simple commands. Say “George, Sit!” as you move a treat in a front-to-back arc over his head. When his cheeks hit the floor say, “Good dog, George!” and give him the treat. Never repeat a command; do repeat corrections as needed. Your fine new dog will catch on fast.
