About – Have Leash Will Train

Please read the following comments so you can be a little more informed about us. Barry Stewart – The Long Island Dog Trainer offers dog training with a distinct difference, by using the dog’s innate pack mentality.

“When I was fourteen years old”, tells Barry Stewart of Have Leash Will Train, Inc. “I had a neighbor that owned a puppy store I worked at. I fell in love. Early on, I knew dogs would be a big part of my life.”

“I started to learn to train puppies there. And I started to learn how to groom there also. I wasn’t much of an artist and I realized I wasn’t going to be a good groomer but I noticed I had an ability to communicate with dogs. Training was my thing and I loved it.”

The dogs I trained in Okinawa in the early seventies were sent to Vietnam

“When I went into the army, I chose the K-9 Corp. The dogs I trained in Okinawa in the early seventies were sent to Vietnam. Realistically, dogs trained for field work must first receive and excel in obedience training. They must know obedience on and off the leash. My dogs were trained to follow commands and to completely trust the handler’s judgment.”

The Dog Trainer adds, “After my military experience, I began training with one of the best dog trainers in the field, where I learned to combine my special talents, my military training, new techniques and unique exercises to create my own particular style.”

“By the late seventies, (yes, I said late seventies) The Have Leash, Will Train seed was planted. Through the eighties and nineties, my Have Leash, Will Train grew from sapling to a young tree. Now we are well into the new millennium and Have Leash, Will Train has become a strong mature tree with deep roots and large spreading branches.”

“Proper training and breaking bad habits usually takes them six to ten lessons,” Barry comments. Adding, “I can help housebreak dogs and crate-training, as well as offer obedience training using verbal and hand signal commands.”

Long Island Dog Trainer

“Just as with toddler children, I take puppies from terrible twos and turn them into well-behaved young dogs. I believe the training process should happen in a real environment – the dog’s home. All dogs are pack animals, having evolved from wolves and all pack animals need a Pack Leader. My training tactics will ensure the owner becomes the Pack Leader”

Every dog can benefit from professional dog training.
