This allows you to hide treats under the compartments which allows your dog to problem-solve to get to the treat. This takes care of their boredom and allows them to be occupied which is a must have with puppies as they are ALWAYS into something. Also if you have a fast eater this can help them slow down while eating. It has 14 flipping and sliding treat compartments that work best with small treats or kibble. None of the parts remove so you don't need to worry about your dog breaking a piece off and choking. It's easy to clean with just soap and water. It's made with bpa free materials so it's safer for themMy dogs love their puzzles. Pretty good quality, ppl often say their dog chewed it or broke it. I pick an evening , get out the puzzles set em up for my babies. They play have a good time . Then I clean em and put away. This is a good way to keep you pet safe from parts broken and to keep them interested. We use as games not for fast eaters. I use very tiny pea size treats . This way they play more than once without filling upWhen it comes to using, this has been working a lot better than I thought it would be with our 2 new puppies. When it comes to using, I'm able to choose which cup or hole that I want to hide our dogs treats. When it comes to the center part, the middle does spin fairly easily but moves without our puppies hurting themselves to get the treats. The covers on the outer areas do require them to really think about how to open them. When done, we found that it's even easier to clean. Just run it through some water and done. Even our older dogs have been trying this and finally were able to figure it out after a few times. Even when trying to lift these covers, they don't pop off easily or break if our dogs step on them.It does keep my new 12ek old puppy entertained. I was surprised how he figured out if you drop it from a higher level the lids will pop open to give him the treats. With doing so, this also show d me the rubber plugs on the bottom to prevent scratching surfaces pops out completely. Luckily he has not found them to eat them but one is still missing so here is hoping.This is great for smart dogs who eat too fast. My beagle used to devour his food so fast it made him sick. Toys like this help because it slows him down but also gets him using his mind.My dachshund puppy loves getting part of his kibble from this. Mental stimulation is super important and this product delivers.Are you looking for something fun for your dogs to do this is a must have my dogs love it it will keep them busy for hours to try and find there treats it was very well worth the money and great for dogs
