I haven't had time to post an update lately...Tucker is doing AMAZINGLY well! We had him neutered about a month ago at 9 months of age. I wanted to wait until he was over a year for health reasons, but behaviorally it had to be done sooner than later. This has made a huge difference in his behavior as well as clicker training, free shaping, lots of walks & controlled play with frisbees, patience & understanding.
It is simply amazing how a relationship can blossom with a dog when you take the time to understand his needs and communicate back to him that everything is going to be ok. I have learned so much from him over the last few months.
