If it's a pointer get yourself a whoa barrel (55 gallon drum works perfect). A 55 gallon drum is cheap. Especially if you're ever up in the area of M-33 north of I-75 at the M-33 warehouse place. Put your dog on it 5 mins every day, I do it twice, once in the morning and once at night. If he moves a leg lift him up, and set him down/drop him down on the barrel all while saying 'whoa'. It has helped my dog tremendously with staying steady. The dog has a hard time keeping balance while on the barrel if he moves his leg. I often times pet his back while lifting his tail and say 'whoa' at the same time. I release him only using the words 'ok Redd' and tap the top of his head when the training is done. Just an idea. Good luck. Between this training exercise and my dog realizing he's not going to get feathers in his mouth without staying steady he has improved vastly even since the beginning of this season (this is his first season).
