    Not durable
    Color: red
    Although it holds about two cups of food or treats, my 40lb dog can bite down hard enough that you can no longer move the dispenser hole. It entertains her for hours but it could be a bit more durable for larger dogs or specify that it is for smaller pups

    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.

    Mental stimulation for dogs and fun to watch!
    Color: Turn Around, Size: Level 2, Color: Turn Around, Size: Level 2
    Perfect mental stimulation for dogs like that like a challenge! My very smart dog figured it out in a few seconds so I use treats that are only a little smaller than the holes to make it more challenging. She doesn’t play with toys like my other dogs so I do make an effort to offer her other outlets to get energy out. I have another dog that finds it challenging, but enjoys it, so I use smaller treats for her to make it easier. I have another dog that has a low tolerance for challenges and walks away from it or tries to chew through it- so I think the level 2 rating is fair as every dog is different! My dogs are 12 lb for reference.
