Bob-A-Lot has a weighted base that tips it back upright after each hit, creating unpredictable kibble dispensing. Dogs can't develop a pattern, which extends engagement time dramatically compared to ball-style dispensers.
KONG Wobbler has a predictable side-to-side motion dogs master quickly. Bob-A-Lot's weighted base creates random tip-and-recovery that stays unpredictable longer. We have not timed sessions. The design case is that an off-center weighted base keeps the tip-and-recover motion less predictable than the Wobbler's symmetrical wobble, which is the reason to expect it to hold attention longer.
Use kibble sized appropriately for the opening adjustment. Smaller openings extend sessions. The upper chamber is for small treats; lower chamber for kibble. Fill both for maximum engagement time.
Dogs who need meal-time enrichment and who've mastered simpler rolling dispensers.
Dogs who get frustrated easily — the unpredictable motion can be discouraging for some.
The best treat dispenser for dogs who've outgrown basic rolling toys. The unpredictable motion is the key differentiator.
