"First of all I have to emphasize how much I love my dog! That being said, finding the right person to take my dog out was extremely important to my peace of mind. Mark not only provides consistent, professional service, but he also really loves my dog. Mark also really knows dogs, their behaviors and the psychology behind their behaviors. Bottom line Mark makes my dog really happy, which makes me really happy."

“My wife and I are very grateful for the service that K9 Extreme provides. We are the owners of a very energetic boxer and we were "fired" by 2 other dog walkers because our dog could be aggressive towards other big dogs out of fear. Mark Assem took Bickford on and has him out 5 days a week now running and playing with big dogs with no issues. Mark hasn't just walked Bickford the past 3 years, he has rigorously exercised him while also training him. Thanks K9 Extreme!”

~Sean Fitzgerald, Larkspur

“Mark understands, appreciates and loves dogs. We trust him with our baby and she adores him. Mark is dependable, reliable and professional. I appreciate that he actually runs with the dogs and is always the leader of the pack.”
