My corgi puppy was about 6 months old when she went to Sit Means Sit. She wasn’t wildly disobedient or have any major behavior problems. She is just stubborn, she likes to listen when she wants to… which is not often. She is not heavily motivated by treats, most programs didn’t get her buy in. She did the board and train here and now she is so much happier! She knows exactly what I want from her and she rarely gets “in trouble”, because she doesn’t act up nearly as much. She knows the expectation. She is still a fun loving puppy, we still have great play time. The difference is now, I can also bring her in public with confidence. We are still in training and she is continuing to make progress! I highly recommend Sit Means Sit
