We have an 18 month old Boxer dog who was absolutely unruly. We had sent him to training with another dog training company and he actually came back after a week of being away worse than when he left. Cadbury was unruly, chewed things especially plants, dug the garden and was very boisterous.
After a phone call to the K9 Centre and several sessions later Cadbury is a different dog! Listen to your trainer its not always the best idea sending them away for training an In-Home lesson program was the best thing for ALL of us.
