WEST PAWZogoflex Toppl Treat Dispensing Dog Toy Puzzle – Interactive Chew Toys for Dogs – Dog Toy for Moderate Chewers, Fetch, Catch – Holds Kibble, Treats, X-Large, Granny Smith

This is by far the best puzzle feeder I've tried so far. I have a couple classic kongs and they are decent. However, Nala get's frustrated easily with them so I have to thaw a little before giving them to her. This thing though? She will lay there and lick her Toppl for over an hour in dead silence - it's incredible.What I've been filling it with: I drizzle peanut butter along the bottom, fill the divots with banana slices, plug the hole with a banana slice, fill the rest with her kibble that's been soaked in water, and drizzle peanut butter on the top. She goes crazy for it!The only minor downside is that it can get messy, so I have to vacuum every time. But well worth it!

I (and the ninja pup, Bugs) love all West Paw products and highly recommend all of their enrichment feeders. The toppl is perfect and a must have for your doggo’s enrichment inventory :) - You can stuff it and layer it, which offers more flavor and variety, even adding a little more liquid. You can freeze it for longer enrichment or stuff it and use for daily meals or snacks.Now that my extreme pro-chewer is older, he no longer tries to chew the toppls like he did his very first toppl. I still use that chewed one though, since it can be stuffed and used. I still think the toppl is durable overall, even for moderate and some advanced chewers. Especially when stuffed and frozen. IMO, I don’t think you’ll be disappointed in any of West Paw products.

I have a rather large german shepherd who has bilious vomiting syndrome. The large Toppls did not hold enough food for him even when filled to the brim with snacks.The XL has much more room to fit “mix-ins” like duck feet without having to wrestle with the little prongs. It’s also big enough to where it doesn’t have to be filled to the brim, which works well for me. The opening is great for larger or more pointed snouts (think mastiff or borzoi).

I was holding out on buying this for awhile because I really didn't like the price tag for just a fancier "kong". Boy was I wrong. First of all I got the XL and it is massive, I believe it could fit about 2 cups of food. I filled this thing up with my puppy's dinner and froze it all day and it kept her engaged and busy for at least an hour and nothing keeps her busy that long. wow, so glad I bought two so I can just rotate through.

I searched a long time for the perfect “kong”-like toy for my mastiff and this is it! He’s a big boy at 120# and the traditional kong is just too small for him. He loves the XL Toppl that we stuff with canned food, green beans, canned pumpkin, kibble, treats,etc then freeze. Great way to keep him busy for awhile when we are not home.
