Who would give their dog a glass bowl anyways. I could see it if you were feeding him and picked it up afterwards. But to make that the regular water/food bowl is just asking for disaster. Although more so from breaking, who would of thunk it could cause a fire too. Talk about a 1:1,000,000,000 odds.
Hmmm..I can't imagine using a glass bowl as their every day bowl either. Shoot my dogs play with their bowls too much to give them glass. I wonder if stainless steel might be a bad idea for the same reason? If it were to be an outside bowl though I can't imagine using anything but plastic. Even that can cause the water to heat up more than I like, but glass is crazy. Bizarre story, but thanks for sharing.
