I had a vicious 3 year old, 8 pound chihuahua who would attack every dog in site until Jackie from Sam Ivy Fort Lauderdale started working with him. We noticed a difference after the 1st session and in a month he was a completely different dog. He is now an angel and can be around other dogs without barking, biting, and lunging towards them. Thank you Jackie!!! Not only is Jackie and amazing trainer, but she is also the nicest person to work with. I highly recommend Jackie from Sam Ivy to anyone who needs help with their pups.
