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.

Durable, Engaging, and Perfect for Small Dogs
Size: Small
The Starmark Everlasting Treat Bento Ball is fantastic! My small dog loves it, and it keeps them entertained for a long time.
The toy is tough and durable, perfect for chewing, and the treat-dispensing feature makes playtime even more engaging. A great way to keep dogs mentally and physically stimulated.

Great toy, just no match for my dog
Size: Large
I love this toy but it was unfortunately no match for my 75lb catahoula leopard dog, it took her about an hour tops to rip the treat out of the ball entirely and walk off with it to eat it 🤣 the side I put a bunch of her smaller treats into kept her busy longer. I'll definitely keep using it, she absolutely loves it, but shes just too good at tearing things up 😅
To be fair, shes a really heavy chewer, and usually gets frozen marrow bones as treats. This is a great alternative, especially for the price, its nice and heavy, she hasnt chewed through the rubber yet, but it probably wont be long. She doesn't throw it around like she does her other balls, but when I toss it to her its got a good bounce.

KEEPS MY ENERGETIC 1 YR OLD LAB BUSY
Size: Large
Anyone that has a field Lab knows you have to keep them busy which is difficult with the snow that won’t melt and the unusual -15 degree windchills we are having in NYC. Like others I’ve wasted so much money on various toys and puzzles trying to keep her busy and mentally stimulated. She either destroys them in minutes or won’t touch them. However, these with treats inside are fantastic. She loves the chicken flavor treats that go inside the ball. The treats for the holder are pricey but worth it so it keeps her busy for a while and she doesn’t get super hyper with cabin fever. Once I can get her back outside for longer periods to play and run off her excess energy I probably won’t be buying them on a regular basis given the price and that they only last a couple of hours given her strong jaws….Probably only for a special treat. However, for now they are worth every penny. The only con is they are difficult to get into the holder which is good so she can’t remove it.
