My avatar is my sweet 92lb bouvier. She burps every night after dinner. Usually in my face. I think (I hope) it's a "thank you".
As for eating inappropriate stuff, whooo boy she's got that covered. One day she snuck upstairs and raided the bathroom garbage. She ate 4 disposable razors. I only know that because the NEXT day the (now fired) babysitter who was there at the time told me "by the way cocoa got into the garbage". No more details than that. So I investigated the garbage pail and found the chewed bottom of the plastic handle to four razors. Later I found a pile of chewed razor blades - just the metal - out in the yard mixed with a little vomit. Elsewhere I found plastic bits in her poop. Not a single drop of blood from her mouth or elsewhere. Whew!
