Yesterday evening, our dog came in with bloody paws. Seems the squirrels knocked my (glass) rain gauge off the fence post so she decided to see how it tasted. It had a laminated clear overlay on it that somewhat held it together, but she chewed it enough to break it, cut her mouth, and bleed all over her front feet. All I could find online was to have her eat some cotton balls which supposedly binds up any glass and makes it easier to pass. This dog'll eat anything that fits in her mouth!
