DIEGO'S FAVORITE OUTSIDE BALL!
Color: Assorted, Size: Medium
JW PET COMPANY HOL-EE ROLLER EXTREME
This is the second HOL-EE ROLLER ball we have purchased for our Diego. He LOVES these! He now owns a black one and a blue one. He loves to toss these around the yard all by himself or have us throw them to him. He looks so adorable when he comes running back to us, with the HOL-EE ROLLER in his mouth and he has the sweetest expression on his face and is so happy he is prancing! He is a rescue Pit mix from PR. He survived Hurricane Maria and was there before, during, and after. If he could only tell us his tale.
The ball is sturdy. The honey comb design gives your baby the ability to grasp and hold the ball. Diego also likes to hold the ball down and gnaw on it. The ball has proven to be safe against his little vampire teeth. The blue ball was in our yard the entire winter during every type of element you can think of. It is is great shape. Diego plays with these balls constantly while outside. They are sturdy and he is able to get a nice grip on them. These balls are tested by the company to make certain they do not contain any harmful chemicals. The ball has plenty of bounce to it too!
The balls come in different colors but which color you receive will be a surprise.
JW products are AWESOME. Diego also has a trio of smaller indoor balls that he has had for three years now. They are still like brand new. He loves to play with these. They have grips on the outside for him to try to chew on, but he can't destroy them.
JW has other types of pet toys and products available for you. Check them out. Your dog will thank you.

Most favorite
Color: Red, Size: Medium
My fur babies love these balls they are their favorite. Any size dog can play with it because of how it's made. it easy to play with. It's made with a lot of opening and is made of a soft rubber. My Shepherd pup and Boston's love to play with it, and I had to buy 3 so they don't fight over it. The giggler will break easy and even the first day on rough riders, but they can still enjoy the ball itself even without the giggler. It size is about 4in. If Amazon gave halves Id give it a 3.5 because of the giggler breaking so easily but otherwise my girls still love this ball.

Wonderful toy, but for most dogs it's a toy you play WITH dog, not a chewie
Color: Red, Size: Medium, Color: Red, Size: Medium
I'm a dog trainer, and have shared my life with many dogs. For the current mini aussie, toys are a necessity and a lifeline. He is tough on toys, and we have certainly tossed many many MANY ruined toys. This toy is wonderful: the squeak is fabulous, it bounces great, it's easy to carry around, and great for fetch and a little tug. Love it, and so does he. But it's soft rubber, so it's a toy to be played JOINTLY with... not a chewie. It will create a lot of fun times and silly entertainment and exercise, but I will put it away when I am not closely monitoring and involved with the play. One of the photos is blurry but shows that the rubber is soft.

Stops giggling after a few weeks
Color: Red, Size: Medium
I have bought three of these Giggler toys. The dogs absolutely LOVE this giggler toy and it's irresistible to them, even more so than squeaky toys. The rubber is soft and flexible, and after weeks of tug-o-war between dogs, the rubber has stood up well and is showing no sign of breakage. However in two of the toys, the giggler mechanism has started to fail and barely makes any noise at all. The dogs have lost interest in them.
