Josh is my go-to trainer. I have a high-drive, shy shepherd cattle dog mix that has been seeing Josh since he was 8 mos old off and on. I’ve done board and trains with Josh as well and he is one of few people I trust with my dog (now about to be five years old).

Josh trained our standard Goldendoodle (Harley) when he was a 10 month old puppy with a one week board and train. We were so pleased with results and Josh’s inclusivity of his family and ours (via live feed) during the training, that we did a second board and train a year later for reactivity to bicycles! Josh is extremely knowledgeable and compassionate and loving to our pup. We have referred all of our friends who need help with training to Josh and they have all had great experiences and results. We just got a new puppy and will be sending her to Josh soon as she’s old enough for his board and train!
I took my dog to Josh for a consultation last year and had a great experience. He was informative, explained everything clearly, and gave us plenty of helpful advice. We had a negative experience with a previous trainer, but Josh was respectful of my dog’s boundaries, which I really appreciated. We came from Livermore, and the drive to Antioch was definitely worth it!!
Highly recommend! It’s hard to find a trainer whose heart is in his work to truly help the dog and owner long term. So many fly by night trainers are out there who use fear and abusive techniques that leave a dog traumatized and often worse. I commend you for all your hard work and look forward to continuing to learn from you and apply that knowledge in my day to day work in dog rescue.
Joshua Beckler is the real deal. He knows his stuff and really specializes in working breeds like German Shepherds and Belgian Malinois, like I have. He is easy to understand and is dedicated to helping you communicate better with your dog and bring out the very best your dog can be. I cannot wait to see what he can help me do with our new Mal, Riggs.
