I did clicker training with my Lab Star and being the VERY food motivated doggie that she is, it worked fabulously! Our trainer said that it is important to use something extra, extra special as the treat, just not some kibble or piece of biscuit or something she normally gets as a treat. She suggested using hot dog, dehydrated pieces! You can do that in the microwave. Cut up 1/2 long pieces and cook them for several minutes. It removes a lot of the unwanted fat and is a lot less messy! I think you're really going to enjoy the clicker training, Guster and Jessica! I'll bet Tasha will come around before long!
