Ben's Dog

Ben The Dog is the pet who lives in Ben's house, presumably possessions belonging to Ben or his father Carl.

The dog only appears in the final episode of Ben 10 Good Bye and Good Recidence, but this episode is considerate of non-canonical, so it may be that the dog never existed or exists. Nor is it in Ben 10: Alien Force, presumably never exisitio, escaped or died in Prosesa 5 years.

in Ben 10: Race Conta Time does not show up, presuming that never existed.

His race is German Shepherd, is not chained and roam freely around the house Tennyson seems to have a sixth sense, since Ben acknowledged even when this was Canonbolt.
