I cannot begin to express my gratitude to Sam Ivy and Thuylinh our amazing trainer. To give you a little history, we adopted our pup from the county shelter. He was diagnosed with a deadly pneumonia that required immediate transfer to ICU upon adoption. After over 6 months of persistent care he was finally deemed healthy. While he was extremely loving, he had become very protective of my fiancé and I following his treatment. He felt that we were his "pack" and did not want anything or anyone to take that away. While he was friendly with other dogs and people we trusted, he would tend to bark and growl at strangers. After reading the reviews we decided to hire Sam Ivy. Thuylinh was assigned our trainer and was nothing less than patient, kind, and full of resourceful information. I will not lie, my fiancé and I were a bit weary of utilizing some of Sam's tools. Once we learned how to properly utilize the tools and saw the quick changes to our pup, we became 100% in! Only 10 sessions later and we have an entirely new dog! Our dog who could never walk on a leash now walks right alongside me and sits when I stop. He looks to my fiancé and I for everything! The best change I have noticed is not with us, but with him. He is a confident dog and who is truly much happier! I could not recommend Sam Ivy, Thuylinh, and their methodologies enough!
