Good Mercer County dog training is about more than teaching sit. Owners in Trenton, Princeton, Hamilton, Lawrence, and Ewing come to Dan Gentile when they want a dog that behaves without being managed every minute.
Pulling, jumping, and ignoring the recall. These habits get set deeper the longer they go on. Our board and train program resets them while your dog stays with us full-time, and the change usually lands inside a couple of weeks.

“In two weeks my energetic little pitbull went from not listening to anything to obeying commands quickly. The little training session at pick-up was especially helpful to ensure we’re doing the right things to reinforce the training. It was tough letting our girl go for two weeks but it was well worth it.”

★★★★★
“I have had many dogs trained by the Dan Gentile Dog Training Center and all were extremely positive. Before I was recommended to Dan Gentile, I had a trainer tell me my dog could not be trained. Dan proved him wrong.”

“My goldendoodle was not the greatest listener when we dropped her off. When we came to get her two weeks later, she was a well-mannered family member. We always receive compliments on her behavior. So thankful that we brought her to Dan!”

“Dan and his crew turned our headstrong puppy into one able to listen and follow commands. He learned how to sit, stay, heel, come, down, and the first night home he lay quietly under the dinner table for an hour surrounded by 8 boisterous adults. It was amazing.”
– Johanna Schoen, Verified Google Review
★★★★★
