Best guess is Darryl Dixon is Hound mixed with Great Dane. He's got the face and the long lanky legs of a Great Dane and the colouring of a Hound. The Hound in him wants to chase the scent. The Dane in him wants to get cozy on the sofa. The Hound in him wants to keep his nose to the ground. The Dane wants to stand up and hang onto your shoulders. Two great dogs in one.
The best way to check on the adoption status of this dog (and other dogs and cats and other small domestic animals) is to visit Toronto Animal Services adoption website or call 416 338 6668 for the Toronto Animal Services South shelter. If the dog is no longer on the TAS adoption website, it's probably because it's been adopted already.
