Okay y’all- I’ll start by saying I NEVER write reviews, but Mark’s exceptional service warrants as many stars as I can give! 5star+. If you’re considering bringing your dog to Mark for training, do not hesitate! We brought our 6 month old puppy Duke to Mark because we were feeling overwhelmed with the training process and Dukes wild ways. Positive reinforcement clicker training only worked when Duke wanted to listen but when he didn’t, we had no way of controlling him. We were worried for his safety, our kids safety, and worried friends and family wouldn’t want to come over b/c of Duke’s rude manners. He would steal our food, growl at us, jump up on everyone, climb all over us on the couch, wander into our neighbors yard and not come to us when being called, pull his leash on walks- basically it was non-stop chaos and exhausting. One week with Mark and Duke has changed in ways I thought were far off dreams. He walks by our side, no leash, and comes when called after we let him roam at the park. He lays quietly on his bed while we eat and work and only leaves when we tell him he can. He sits at the door when we open it until we say “come” (for his safety), his jumping up on people has practically stopped. Honestly, it’s night and day and I can finally breathe again. To get the most of the training, it’s super important to learn from Mark’s ways, listen to his advice, and keep up with the training after the initial week with Mark. I’ve seen first hand how doing so continues to solidify the good behavior. It just keeps getting better. Thank you so very much, Mark, for your expertise and giving Duke such superb attention!! And hugs from your boy Duke. He’s happy to be home but misses you.
