My pups really enjoy playing with this toy! They work together to get the treats out. Though the slightly smaller younger dog has it down more than the other, the other benefits from his work! It is definitely a great purchase.Now have 2 of them and dogs love them. Dogs are 15 - 20 pound terriers and get good and rough getting the food out knocking them around like hockey pucks. Toys are holding up great and still look like new. Just the right amount of food comes out to keep them interested, but also keep them interacting with it for 10 - 15 minutes to totally empty. Like the adjustable opening for different sized food as dogs are on different diets.Works well for entertainment but he chewed the top spikes off in a moment of frustration.I have a 7 month Rottweiler. We got this on a promotion so i wouldn't be heart broken when she destroyed it. She chewed the top horns off on the first try and scratched the plastic all up, but it's still usable and functioning. It's a good enrichment toy when we have to crate herI have bought two different kinds of this one was easy to open the other one was not like my cat still have a hard time taking out The foodi think the only thing i wish was different was the hole that the treats come out. you can adjust how big the hole it but it’s not gonna stay it’ll open more which makes it easier for my smart dog but she still has to work for the snacksMy doggy really loves this toy and he loves trying to get the treats out of it
