Shiver me Timber! Our big boy, Timber is the most perfect gentle giant! Timber is a little shy at first but that’s only because the big city is so new for him. He’s looking for a patient home that can go slow with him and show him the ropes. Timber loved all of the dogs at Muttville – big and small – so we think he’d love having some furry friends! Timber is guesstimated to be 9 years old and weighs 78 lbs.
