Jeff is unlocked by joining the official Billion Duck Hunters group — no Feathers, no Robux. He is 'just' a Common dog, but with Capacity and Walk Speed upgrades he keeps up deep into a run, auto-depositing ducks once you buy Dexterity. Most veteran runs still star Jeff.

Notes

• You can pet him.

Dog upgrades (any dog)

• Capacity — ducks carried per trip (starts at 1; the single best early upgrade).
• Walk Speed — faster fetch loops, less waiting between volleys.
• Dexterity — auto-deposits ducks into the freezer so you never walk back yourself.
