Well, I had a successful day.

Jersey loved the dehydrated beef heart, tongue and pork liver the best. Which is great because he is eating low-quality kibble like Pedigree and having an all-meat treat will really benefit him. Also it is the cheapest because I made it!
I took all the treats I brought [banana, carrot, bread, cheese curds, hot dogs, kibble and the dehydrated foods] and laid them out in front of them in his crate. Then I left the room for a moment and when I came back, everything but the dehydrated foods had been rejected.
Then I sat in front of his crate [at first I was standing but this made him very uneasy] and tossed treats in while talking in a soothing voice, until eventually he was taking them out of my hand. It only took about 10 treats to get to that point. He kept taking them until a man walked into the room. He paid us no mind, didn't even walk near us, but Jersey remained perfectly still until the man was gone.
A lot of other people [mostly women] and dogs came through our room while we were sitting there. Jersey didn't mind most of the women, except one who I learned afterwards was the wife of a man who had walked right past Jersey's crate while we were having our pow-wow.
After a while I decided to take Jersey for a walk, and see if he'd let me pet him. Not only did he tolerate that [tail down but not tucked under, I was petting his shoulder while sitting] but after a while he started looking at me, and I'd feed him a treat. :D

I didn't work a lot today with Cookie because I was on a time budget, but I did make him an extra-special kong. I took a bunch of Jersey's treats, mostly the pieces that were fatty, and I froze them inside a kong, then I filled it with chicken stock and put it in the freezer overnight. He loved it! And it kept him busy for quite a while.

I did a bit of training with the loud dogs in the hound room [the loudest room we have] and out of the 12 dogs in there only 2 didn't get it the first time. The one got it the second time, and the other took four times before he got it. When he did, though, I gave him a "jackpot" and made a big fuss. I also did this while carrying a leash and going up to random crates, opening the doors, and closing them. Next time I go I'll take a dog around with me, since their biggest problem is barking when there's another dog out of its crate and they're in theirs.
