We have two Malti-poos, aged 4 and 2. Both used to bark to a ridiculous level when anyone came to the door or walked by our house (even on the other side of the street). Taking the dogs out to use the bathroom required looking both ways first to be sure no one was around. Totally embarrassing! Finally broke down and called Greg. Within 5 minutes of Greg being in the house, the dog were much different. After a few hours, we had the confidence to better control our dogs and the tool to improve our place as pack leaders. Greg took the time to explain his reasons for everything he taught us and the how and why behind our dogs' outrageous behavior. Greg accompanied us while taking walks around the neighborhood, utilized stuffed dogs to simulate stimuli that usually set the dogs off, and was always kind and constructive in his critiquing of what we were doing well and what we needed to continue to work on. I highly recommend Greg to anyone with dogs that bark, display aggressive behaviors, jump, etc. Thanks a ton, Greg! Our dogs are a pleasure to be around, and we don't worry about taking them out or when the neighbors are outside.
