When we fed kibble, I exclusively used puzzle toys and treat balls to feed Lena - otherwise her food would be gone in under 10 seconds!
Our favorite is
Omega Paw Tricky Treat Ball, GREAT for pretty much any size kibble (Fromm is much easier to get out of it than a standard size kibble, though). The only thing I don't like is that it's not easily washable, but since we only used it for dry food, it wasn't a huge deal. The Large size holds about 1.5 Cups of kibble. (The emptier it is, the harder they have to work for it!
We also used something similar to a
Kong Wobbler, but it was an off brand thing that we got at Target, I think? I liked that we could take the top off and give it a good scrub every now and again.
Tug-a-Jug is another good option, when the rope gets destroyed or too nasty, just put a small ball inside the jug with the kibble, and that will work just as well!
