Mark really helped us with our young Briard. We really needed help with aggressive behavior on walks. She is doing so much better after one training.

Our rescue is so grateful to Mark. We have helped dogs for 12 years and Mark is one of the few trainers who truly knows what he's doing and you get your money's worth. We refer our adopters from all over the country to him which works since he can do Zoom sessions. They always say how great he was and truly have a plan to work with their dog! I have complete confidence in him and am so grateful that he exists!!
Mark is the best! He is super knowledgeable. You can tell he sincerely cares for dogs and wants the best for them. He has taught us how to best work with our aggressive dog, and we are so happy

Mark has been invaluable to me and to our family. I met Mark about 12 years ago when we had our Labrador puppy who was, well, a Labrador. He worked with us for months to get her to be a well behaved, civilized and lovely dog who was able to work with me for years in my job at hospice. When we added a shelter pup to our family four years ago, he came to the rescue again. This time during covid and on zoom, all the while we were living in Portugal. He met with us to help us work through all this pups fears, oddities, and some aggressions. After our lab died, he helped us help our dog learn to adjust. Fast forward to now. We have continued to work with Mark remotely as we have added in another older rescue to the family. He's been nothing but a godsend. He knows how to help us learn to read our pets with our gut and our heart. If you have any doubts, reach out to Mark and his team. It's been such a relief knowing he is there, even miles away, to help us navigate whatever comes up. Thank you Mark and LOTP!

I found Mark and Leader of the Pack through a series of links from a YouTube video and I'm glad I did. I have a 2 year old cattle dog who started to develop some reactive/leash aggression which never happened before. I tried different methods but nothing seemed to work. I wanted to find some help fast! With Marks experience with cattle dogs, I felt like he knew exactly what I was talking about. We talked about why dogs do certain things and what I can do differently with my training. After 1 training session, I saw immediate results with my dog! It was amazing to see that I was starting to go on the right track with some guidance. Thank you for the help!
