Treat toy

[siam]

Not quite sure where to post this so thought I'd try here.

I got Alfie a Tretbon treat toy in the S M size for his birthday today. We put a few small pieces of kibble in either end but despite some nifty footwork on Alfie's part he was unsuccessful in getting any out. My son shook it really hard and even then was unable to get any out. Has anyone else's pooch successfully used one of these and if so any tips please?

Tried one of these (sort of) made by Kong, filled it with his food - wet - and a few star treats, the food was still in it when I got home, not very successful for Minstrel. I bought him a treat ball instead, and he has fun, nosing it along the floor getting out the treats
