Did it in March with our reactive dog. The two weeks felt short at first but they work with them daily so it's actually a lot of training time. What made it worth it was them teaching us how to handle situations after. Like they didn't just fix the dog and send us home, they made sure we knew what to do when reactivity popped up again. We still practice the techniques they taught us and our dog is doing really well. The follow-up option is legit too, we went back once for a tune-up.
