I have a few items, I try not to look like the crazy neighborhood lab lady though. I have found some cute things on Etsy. The Stephen Huneck Gallery has some prints or other household items. I also have a couple of prints by Sara England that I think are really cute.

I have a metal leash hook and a small metal planter stake I got on Etsy.
