Its a hit for my 9lb chewer!
Style: Chilly Penguin, Size: Small (Pack of 1)
So far so good! My Pup is a chewer and destroys most of his toys. This has been great to keep him happy and occupied for about an hour. I work from home, so when I know I need to keep him busy this is perfect. Ill keep an eye on it to make sure he doesn't break it, but it is pretty solid and thick. He can get through a puzzle in seconds, so this has been so good for him. Ive done mostly broth and veggies, some kibble. Even yogurt and peanut butter. Right now he gets it twice a day. He spends about an hour with it and then hes so tired hes ready for a nap. Once around mid day and another late evening before bed. Im ordering another to keep for when I have to leave him home alone. He cleans it pretty well, but Ive found soaking in hot water also loosens any bits left behind. Because its small, I'm not worried about extra calories.

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.

Great tool!
Color: Flip Board, Size: Level 2
Love this interactive toy! I purchased this for our 4 month old husky, looking for something to keep her entertained, and I was not let down! In the beginning, it took her a few good minutes to figure it out, and about a week later, she gets it done in about 2 minutes. If you've never had a husky, let me tell you, these dogs are very inquisitive! But due to her being involved with this, our older pit is now getting in on the fun! This is huge because our pit isn't amused by much! Overall, it's durable enough to withstand puppy chewing, and being carried around. It's also super easy to wipe clean as it's some sort of durable, perhaps reinforced layers of plastic. Even though the puppy figured it out, it still seems to excite her, and considering it keeps both dogs entertained and active mentally, I would absolutely recommend this to any dog owner!
