A donkey with wings! Who knew!
Baxter loves it & it's been a new go to from out of the box. Very durable material, crunchy ears & wings (not sure why a donkey has wings, but ok 🤭) Very cute, great colors. The only downside is the squeaker is hidden between the face attached to the front side of donkeys head, so it's the thickest & toughest part of the toy. It 's hard to squeeze to make it squeak or hear the sound. Only larger dogs can open their mouths wide enough to bite down for it to squeak, mine can't. But cute toy & if it's a gift it comes in it's own cardboard boxlike container.
