I am writing this review because I have never been so angry. Jolean is a Dog trainer based in Long Island, where I sent my 8-month-old dog Jasper to her two week Board and Train Program. Jolean had 12 very positive reviews, so I felt comfortable and happy sending and have my dog in her care. However, Jolean failed to mention a massive part of how she was going to train Jasper, with a Stym collar. Any use of e-collars to train a dog is a negative reinforcement training technique. I am aware and understand people train their dogs left and right, but that is not a method I would ever choose. The use of collars was not said to me when dropping Jasper off; it is not stated anywhere on her website or her Liability Release form. The only mention of it is on her Payment portion on the contract, and it says, 'I also understand that the remote collars are not to be left unattended or on the dog overnight, and I will read the collar instructions as provided by the manufacturer.' Because this was the only mention, I thought it was merely a collar he had to wear under her care at her facility. The language in her contract is ambiguous to the point of purposeful deception. How do you not provide intensive information about such an important topic regarding training? I found out she was using a collar when I picked Jasper up after the two weeks, and she handed me the box and instructions. Since having Jasper back, he has shown never before aggression towards me. I questioned it and told Jolean, her response was, 'It's either he is growing up, and his true personality is coming out, or his border collie nipping is. Or you're using the collar the wrong way.' Nice, huh? To add to the situation, during the drop-off, I asked to see where Jasper will be sleeping at night. She refused and went on to tell me its illegal to show me. It makes you question the conditions these dogs will be under while in her care. I refused to continue using the collar with Jasper as I do not believe in negative reinforcement training. Jasper reverted to all old ways. What did I pay for? I asked for partial payment back, and Jolean refused. Her contract states no-refunds yet fails to mention the considerable part of her training methods.
