I don't really have much to offer, as I'm finishing up the last of the red tape before I can open up, but unless you're gonna be setting up near strip clubs or a porn studio or something, I don't think "Horn Dogs" would go over very well. Someone suggested to me once to name my cart "My Wiener, Your Mouth". It'd probably be a big hit on a college campus though.
As for Devil Dogs, there's already a snack called those and I've never heard of any zealots going nuts over that, and even if they did have a problem with your name, just make something up and say it's a take on Tazmanian Devil or something and they'll probably leave you alone and go look for someone else to judge. (I'm not anti-religious, I'm just anti-zealot).
Friendly Skip's Dogs 'n' Chips (I'd go with 'n' over &, but that's just me) is a catchy name too. It's a bit long though, but I'd imagine your regulars would eventually just call it "Friendly Skip's" or just "Skip's" eventually.
I also read the "Hot Dog Cash" book, and it had a lot of great info. It's actually better to listen to the CDs that came with it than to read it though if you haven't already, because the book was transcripted word for word from the audio, including every tiny little stutter or change of thought/self correction that wasn't necessary to be transcripted, which resulted in a lot of basic sentences making no sense. I read the book and then listened to the CDs, and it made way more sense hearing the audio.
It was a great buy for me though and gave me almost all the information I needed to know to get started, I'd recommend it to anyone. I've read some other things too and they just weren't nearly as good, but I never checked out "Carts of Cash"
Anyway, hope that helps some.
