Needs to sell replacement popcorns
Style: Popcorn Bucket
My dog love this toy however, we have 5 popcorn buckets and only two popcorn balls left. It would be great if there was way to just buy the replacement popcorns. I haven't found them anywhere though.

Bento Ball for the Win!
Size: Large
I got the Starmark Everlasting Bento Ball for my doodle, and it’s quickly become one of their favorite toys.
First off, it’s super durable—which is a must for doodles that love to chew. This ball is made from tough material designed for aggressive chewers, and it actually holds up really well over time.
What I love most is the mental stimulation. You can fill it with treats or kibble and even add a harder “cap” treat on top, so your dog has to work for it. It keeps my doodle busy and entertained way longer than a regular toy.
The erratic rolling design is another win—it doesn’t just roll straight, so it keeps your dog engaged and curious. Bonus: the textured surface helps with light dental cleaning while they chew. 🦷
👍 Pros:
• Extremely durable (great for doodles/chewers)
• Keeps dogs mentally engaged
• Doubles as a slow feeder
• Easy to clean (top-rack dishwasher safe)

Very Durable and keeps dog busy
Size: Medium
We have a dog who loves to chew up EVERYTHING!! She is constantly getting into things and if she can't reach an item of interest, she will find a way to get it, even if it means jumping up on the counter or pool table. LOL. We've tried every puzzle toy and treat you can imagine to keep her busy and tire her out mentally, but nothing really worked that well. She would figure the puzzles out quickly and become board with them after several uses, and preferred to try and chew up the plastic instead. Treats, like bully sticks, that should last a "long time" were gone within 10 minutes. I didn't have high hopes for this product given the history of our dog, but I WAS WRONG!!! The treat was already in the ball when it arrived, so I gave it to her like that. She licked, pawed, and chewed at this treat for hours and did not get board with it. She wore down a little of the dome shape on the treat by the end of the night, but there was still a lot left when I took it up. I gave it to her again the next evening and again it kept her busy. By the third day, the treat was worn down to a ring shape so I took the treat out of the ball and gave it to her. She ate it in about 3 minutes. After examining the ball, it is still in good shape with no damage like we found with hard plastic toys like the kong wobbler. We will definitely be ordering the refills to use with this ball. Best product we have found for busy, destructive dogs who become board easily.
