Durable and Resilient
Color: yellow/orange
I fill the dispenser with their normal Kibble food. It's my slow feeder and herding toy. Every morning the Mini Aussies look forward to taking turns pushing this dispenser around as the Kibble falls out. They never miss a Kibble! Often times they push it so hard it hits the kitchen cabinets and literally flys airborne dropping Kibble! This is extremely durable and resilient. Rarely needs to be washed. Easily hand wash when needed. Highly recommend. This is my 2d one purchased. The first one still works but after about one year of use I noticed the plastic thread to screw on top has been damaged. It still works but want to be prepared if it cannot be used safely anymore. Enjoy! The Aussies sure do!

Toy for Pup
Color: yellow/orange
The only toy that my dog will play with. It helps keep him busy while I'm cleaning. It is suitable for small dogs and safe for them. He twists and turns it around but the toy is still in good condition so the quality is great.

Great Enrichment Toy for Treats or Kibble!
Color: red
I love this toy—and so do my dogs! It’s perfect for daily enrichment and works great as a kibble feeder too. It holds a generous amount (about 3 cups), rolls smoothly, and keeps my dogs mentally engaged while they work for their food. One of my favorite features is the adjustable treat holes. You can easily change the difficulty level, which makes it suitable for dogs of all sizes and skill levels. Whether you have a beginner or a more experienced puzzle solver, this toy adapts perfectly. It’s well-made, easy to clean, and durable enough for everyday use. This has been a great addition to our routine and helps slow down eating while keeping my dogs entertained and stimulated. Highly recommend for anyone looking to add more enrichment to their dog’s day!

Doesn't break easily
Color: yellow/orange
This toy works really good. I bought it from my daughter's dog when they bring her over but it ended up the cat. Loved it and knows how to play with it. Better than the dog did. LOL
