My lab puppy just graduated from the 5 week group class, and I can't stop singing Mark's praises. With his coaching and a little help from Mac's new gentle leader, it was a night and day difference. At the very least, he probably saved me from rotator cuff problems in the future. Even though there were 4 other dogs in the class, Mark definitely gave each pup and owner some personalized attention, and tailored the commands to each dog. It was amazing to see my rambunctious pup progress from one class to the next, and become a (mostly) better behaved dog. We still have a few things to work out, but Mark definitely gave us a good foundation to build on!
