Need opinion re: dog topic to cover for donations?

It's getting to be the time where i start setting up the information and things i need to set up my table at our annual summer garage sale. Some people think i'm crazy for thinking of this so soon but it gives me something to do and i'm not left rushing in the end.

Last year i was able to donate $30 (money i made form selling brownies and hand made beaded jewelry) to help end puppy mills and donated another $30 to my local shelter. I passed out over 40 brochures and talked to dozens of people.

This year i want to offer more items for sale in hopes of making more money to donate. But i'm torn as to what topic to cover and what i could sell. So I set up a poll on my website - if you all would vote and let me know (or let me know through an answer) then that would be great!

Legit (just in case this isn't a legit question): Does your dog always wear a collar or do you let him/her/them run around "naked"?
