Pets and Expensive Dental Chew Toys

Today, it happened, for the first time in 2012. I usually see it about once per year, and I'm not talking about the rate at which my father shoots a hole in one (last year he had two!). One of my patients brought in a mangled nightguard, thoroughly enjoyed by his dear canine companion. I have never heard of a more expensive chew toy! I love my dog, Buster, but if he got hold of my sleep apnea appliance, he would be, well, in the doghouse. So beware, fellow dog lovers, and keep those nightguards and sleep apnea appliances secure in their cases and placed high on a shelf. Does anyone out there have a similar pet story? Or a hole in one? Please share...
Cheers,
