How I avoid smelly farts.

This dog is wearing a gas mask.

Please don't eat beans & eggs again.

While it doesn't look like this dog's mask fits him very well, dogs have worn shields to protect them in battle, even in ancient Greek times.

Today, police, war, and hog dogs often wear armor, Kevlar, and bullet proof vests. I saw one dog on TV wearing a scuba thing with a bubble around his head.
