A Jolly Ball - A Treat Ball!
Color: Red + Yellow
In the past, I got my girls a doggie jolly ball. They played with that thing until they tore it apart! I've also gotten them several different, but similar, treat balls over the years.
Fast forward to present! I found the best of both worlds! A Jolly Treat Ball!
Upon receiving these two balls, first, I was so glad to find that they didn't stink! Literally, no terrible smell! YAY! Second, the jolly treat balls are durable. I placed a large treat in each of the balls and handed them over. Each girl took the ball by the handle and pranced to their desired location to devour their treat! Devour, they did... NOT! Because of the durability and construction of these balls, it took them a good 5 minutes to fully get each morsel of their large cookie! YAY! Once emptied, I asked them to bring it. They each picked up their ball, by the handle and brought it to me. Too cute - they each got just one more treat!
Now that they've utilized their jolly treat ball I have yet to see a single tooth mark in the ball. It has withstood their chewing to release the treat and hasn't been marred or scarred by their strong teeth.
I've also had the opportunity; after each use, to wash the jolly treat balls. They even withstand a scrubby to get them cleaned!
If I could, this "Durable Dog Chew Ball Toy" would get 10 stars! I'm one happy dog momma!

Great play and chew toy!
Pattern Name: Star
The dogs love these!
They're sturdy and give them plenty of chew time. The size is great and they are very playable. The dogs have a lot of fun and the weight is just enough for our little dogs.
