The deal with the microchip is this: He is chipped, and the vet gave us the owners info to try to contact them. Their address isn't current, none of their numbers are connected, and I don't have names. All I found out is that his shots were current, he's six and that his name was Smokey. He doesn't respond to Smokey at all, I tried. Went with Hunter because he responded to it, now he knows that's his name. Anyway, when I talked to my friend at the rescue she recognized him by the name Smokey. She had also been to their prior address. She insinuated that the owners were negligent and said everything short of him being better off with us. We put up posters regardless, because who knows, someone else could have taken him in before I did. Still haven't heard anything, so he's my boy now. Oh, he is neutered.
Minor success story to relate. Worked on the positive reinforcement today on a walk, with firm a firm "No" when he pulled excessively and treats when he listened and a "Good boy, Hunter!". At first we spent 10 minutes on our block. Every "No" provided him an opportunity to smell anything within the radius. I would then walk the other direction to show him that I was leading and setting the pace. Eventually he ran out of things to smell and got bored, then treats, and after about a half hour, he was really getting it. Still pulling a little, but he was looking up at me like I was the one showing him where to go. Or maybe he was just getting impatient and wondering "What on Earth are you doing?". Either way, for the first time, we were walking together.
I'm going to call later today and ask Peggy for her recommendations on local trainers that might be inexpensive. I know they aren't massively expensive, but I'm only 24 and just simply don't have a lot of disposable income at the moment.
House training hasn't been much of an issue, I think the reduction of stress has helped a lot, as well as developing our routine.
With the dog park, I only go if it's empty, and he's only been off leash once. He teared around the perimeter, but when I started running with him he took a chomp at my arm. Didn't enjoy that.
