Hello, my name is Brian. My dog, Tuck, is a Jack Russel Terrier. He was born in November 2010. I have been training him with the help of Kikopup Youtube videos. He is very obedient when it comes to most simple commands such as "sit","down", "leave it", "high five", and most importantly, "come"! He is very well potty trained, he hasn't had any accidents in several weeks. I have been trying to teach him rear end awareness, which has been very challenging. He seems to get board with it after a while, even with his favorite treats, moist and meaty's. I don't know if i should give him a break, or change up the training. For example, retrieving a toy and to "drop it" on cue. Is that like letting him control the criteria? Otherwise, he is a great dog, he listens well even through most distractions. He just has to cool off on the jumping up and the occasional playful biting of guests.
