Hamlet is a Briard breed from a unknown country supposedly not known to the human kind. Hamlet is one of the main characters of The Outer Crew and is very eccentric and does things most dogs shouldn't do. Brian Griffin, Hamlet's intelligent cousin from Seth Macfarlane's American TV Program Family Guy, is supposedly Hamlet's cousins. In the Animation TV special, Animation Showdown, Brian, Hamlet, Ladybird, and Doggie, have a crazy butt sniff break out and turns out Hamlet and Brian are cousins.
Because Hamlet is a Medium Breed, his age of 24 makes sense since he isn't a Small Breed.
