“Mine at light bulbs. And digested them.”
I too owned a glass-eating dog, but I did not know it until years after the fact. My sister had convinced me to adapt a stray that she found six months previously. The dog was a mix of Australian Shepherd and Collie, as best we as could figure. The dog was absolutely wonderful but he had a touchy stomach and we had to be careful about his diet. Years later, my sister sheepishly confessed: the dog ate a pair of glasses. She found came home and found a mangled plastic frame, but both glass lenses were entirely missing. The vet dismissed the idea the that George ate the lenses and besides, the glass would not show up on x-rays. My sister wasn’t convinced, so she fed George lots of bread and for days and washed out all the poop in strainers while sifting for evidence. Sure enough, long thin shards of curved glass emerged looking like scimitars. Small wonder the dog had a touchy stomach, but he lived to at least 14 years.
I never had a dog that wasn’t food motivated and have concluded that dogs are idiots (but I love them anyway!).
I love them anyway, too. My current dog is not that much of a chowhound and has never stolen anything.
I do remember a photo of someone who owned a black lab who made a Christmas card out her dog’s xray - he had eaten the Xmas lights...
