I'm having some issues with my dog creeping at the line for marks. How or what is the best way to put an end to this? I have several friends say that in training, if the dog moves in the slightest bit to pick the dog up and not let it get the retrieve. Retry again about 15 minutes later and repeat again if it happens again. In a way it makes since. Another question, is there another way to make the dog understand that no moving at the line equals getting the retrieve? I'm not saying that picking the dog up won't work but if he doesn't understand why is being picked up after several attempts i've gotten nowhere. I've just finished my Seasoned Title in UKC and want to fix this before i even think about moving to "Finished" or "Master" level. It's not a "Control Break" creep and the judges never said anything about it but i don't want him moving at all. He moves approximately 1-1/2 to 2 foot up when marks are thrown. Any suggestions or tips you guys do in training to nip this in the butt?
