[Hunger Games] What did the Mutt in the 75th Hunger Games actually look like?

During the 75th Hunger Games, a Mutt was released into the arena.

We never get a detailed description of it.

We only know that it was extremely large, very fast and apparently carnivorous, tearing apart a Tribute so badly that he/she couldn't be identified afterwards.

What did this beast actually look like? What kind of creature did the Capitol engineer for this game?

Was it a reptile, a mammal, a giant insect, what?

It could have being one of those mutts that they release into the sewer in the third book. In the movies they are quite weak individually but in the books they are insanely fast and strong. It would also make sense because Snow enjoys fucking with people, and it would terrify the tributes that may have seen the beasts before.
