Ruff-Ruff is a red and black who always says "ruff"; he is a playful dog, with a bone. Ruff lost farmer Fred's list in A Farmyard Adventure once. He is voiced by Ethan Drake Davis and Joseph West in the UK.
- Like Dave, he is very silly at times.
- He and Tweet are the only two main characters with animal sounds as names.
- Ruff-Ruff loves to chase around Mr. Squirrel whenever he appears.
- At the end of each episode with the exception of A Christmas Adventure when the final guessing game starts, he is seen playing with his yellow ball.￼
- He acts like a real dog because of his digging, he loves playing ball, barks, and loves his bone.
