AMAZING to say the least. I’m SHOCKED to see any bad reviews about Sit Means Sit. It takes a village and if you aren’t committed to helping your animal then you cannot blame a trainer. We have a 1 year old German Shepherd that was uncontrollable – walking was almost impossible – some food aggression – Kennel aggression at times – mouthy and it made me nervous for my children. We had no idea how to correct his negative behaviors. Jack has improved tremendously. We have done 5 private lessons and are going to do a few more. we have mainly worked with Michelle & Mike for a lesson as well and they are so great to work with! They go off your needs and so much gets done in the 1 hour private session. The shock collar that is included is way better than the one we got off amazon. No it does not hurt your dog, it gets their attention. If you are seeking a trainer go NO FURTHER. Sit Means Sit is the place to go!!!! We are SO pleased! Thank you guys!
