Gwy (pronounced a bit like "gooey") is a gwyllgi, a mythical type of dog from Wales. It is genderless and can be referred to using any pronouns. Despite its fearsome appearance, Gwy is docile and enjoys things normal dogs enjoy, like treats, playing fetch, and slobbering on everything.

I'd give it a treat, but by the looks of that spine, I don't think it would make it to its stomach =w=
