What smells like old innertube and peanuts?

[TomSD]

I found that out today. Harper had been going to town on his kong full of kibble and peanut butter when he looked up at me and belched. Wow, I've smelled some strange things in my day but that has to rank pretty high up there. I think it was the car tire smell that really set it off though, lol. Considering how strong that ultra heavy duty Kong smells I don't know why I was surprised his breath smelled like it too.
