A friend sent me a photo of her stuffed toy Star Trek Travelling Companion, which inspired me to Show and Tell too.
This is Waxo the Terrier, made for me, sans Star Trek insignia, by Hannah in England (and named by her young son Josh). bink and I made ST pins for my birthday a couple years ago, and this is a leftover one.
Waxo has Spock-like qualities, but Spock can't be anything but a cat. Kirk's a dog, of course. I think Waxo may be their offspring.
