My dog just turned 15 months and has turned into a little monster! He goes to training 2 times a week with a very excellent trainer. About 2 weeks ago he got back from a 10 day board and train program at my trainer's and I have really started to see him in a whole new light. I feel like he doesn't respect me (constantly testing me) and it's frustrating. I train him 4-5 times a day (mentally & physically) but he constantly looks off to the side, to the grass, constantly giving me the finger. I still handfeed him and go by nothing is for free. He also is starting to lunge and pull and bark at other dogs when they look at him. He also is turning hyperactive inside, he has a tougher time calming down and jut yesterday he chewed something up (he never does that). I have tried adding more training short training sessions but he goes off to sniff some trees and has very selective hearing. Also he had a fit today and he hasn't had one since he has 6 months (starts biting and jumping everywhere (hyperactively)). I am getting stressed and I know I still have months of this. What more can I do? Thanks ahead of time guys!
