We keep our dog's food right next to his bowl. He's not interested until he hears the bag and gets real excited when it's open and the cup makes that digging sound.

He's never touched or even shown any interest in the bag itself. The situation and timing matter more to him than hunger and smell from a not very well closed bag I guess. He could bump it and it would tip over spilling the contents but I'd bet he wouldn't eat his fill unless everyone was home and walked past it. They all know their place I guess.

There was an interesting little discussion about bears and gas at our Copia dinner. I have a bottle with bite marks in my office and it seems that's not as unusual as I thought. Still not going to bother hanging my fuel bottles since my toothpaste (that hangs in a mesh bag within easy reach of the fireplace at every campsite) has never been touched by any mammal besides humans.

I'll always hang my rum with the food though.  ;)
