Sit Means Sit is one amazing company to work with! They have made a huge improvement in my family’s relationship with our pet, Smokey. He is still young and so rowdy we were ready to just give up…. He would pull so badly on his leash…jump all over people….be overly friendly with other animals….and much more. In the two months we have been with Sit Means Sit, Smokey has made a huge improvement! He loves his collar and loves that he has so much more freedom now! I am so glad we came across Matt and this company! Life saver, and if I had the chance to make this choice all over again, I would do it 100% with no thought at all!
