I like how my dogs like to chase & hit it to get the treat. I didn’t realize how small it was. I have mini schnauzers, but their food & most treats are too big to fit the holes. But, they like playing with itI just got and put down for my 11 week old dachshund puppy, she immediately went and started using it. She only weighs 4.5 pounds and it is bigger than her, but it does NOT stay put. I would still recommend it anyway, because it stimulates her and somewhat slows her eating too fast. I have had less than 24 hrs so the durability is yet to be determined.Dog likes it, keeps him busy for a bit. I wanted to use it as a slow feed for part of his breakfast before work because I don't want to overload on treats every day. Unfortunately, the hole for the treats or food to come out is way too small for most food or even most treats to fall out so it doesn't work super well. What we've been doing is closing the helmet half way and letting him play with it like that instead.My puppy loves this toy/feeder! He almost prefers this over eating out of his bowl. Endless fun and treats!This is great for my 10 lbs yorkie. He did manage to pull the two stoppers off the front. But it works perfectly without them. It’s a little noisy but he keeps him busy.We had gotten this for our little English Cream Golden retriever puppy. We learned about dog enrichment (not to mention she inhales her food) and wanted to try this because the puzzle we got for the older dogs was too tough for her. She definitely caught on quick using the second largest setting. It’s cool because you can change how large or small the hole is that drops the food out. Really we could only use this for her entire meal until she was about 30 pounds. Will definitely use this for future puppies or for treats.Primero juguete que le llama la atención a mi perro.It keeps my puppy entertained. Until she finishes all the treats inside the toy. Love it
