Hi! We are pretty new. My little Jessie is now eight months old and seems very strong willed. We've been trying to learn the basics, sit, come, where to potty, etc. but she just isn't interested in any of it. I have tried many of the ways that you have all listed. I cannot find a treat she is interested in. And no matter how much attention we give her for "positive reinforcement" the next time she may come and then she may decide she doesn't want to. Uhg! Any help?
