La Beste Glatissant by kate
From the french "Merlin" novel (14th century):
King Arthur meeting a strange Beast in the forest. (If I translated the original text right, that animal has "The head of a dog, the legs of a stag, feathers like a bird around the neck and the tail of a lion." Moreover, the "Beste" makes the sound of fifty barking dogs.
...I want a pet like that.
