We began working David to help us with getting our dog, Zyrus, to walk on a leash along with a few other behaviors. Zyrus is a lab mix and is a big, strong rambunctious puppy. We needed assistance to help control our large puppy better! In our private lessons, David was a pleasure to work with and full of helpful ideas. He patiently helped us teach Zyrus to obey commands, stay for extended periods of time, greet people appropriately without jumping on them, and he greatly improved Zyrus’ walking on a leash. David was equally helpful in training us to confidently handle Zyrus. I have already recommended David to another friend! You will not regret your decision to work with David. Zyrus misses seeing him regularly!
