Fun to fetch
Size: 5 Inch, Color: Red, Size: 5 Inch, Color: Red
Perfect size for my 1 yr old Cavapoo that is ball obsessed. This ball is fun to toss around in the yard to exercise and wear out my energetic boy. Perfect for after my work day when I don’t have the energy to match his energy level. He gets to run and chase and I can enjoy his playtime too. Overall the ball is durable and I have confidence it will last for a very long time. We have 2 sizes, small and medium, for my 30 pound athletic pup. He enjoys both equally.

Dog loves them
Size: 6 Inch, Color: Independence Day
My dog loved the first ball I got her, so I got her a second one. Both hhavr been very durable (she likes to puncture things with her teeth). I left each ball slightly deflated, so they were still firm, but she could bite them without issues. She has not punctured either ball yet. I did have to watch her because she started trying to chew the tabs off because she was bored. She has not chewed one off, just started thinking about it, and did a tiny bit of damage to one tab.
She loves these balls. We have played tug of wat with them too, so yhe tabs are sturdy, and so is the ball.
The dog did not care what collar she got, so I grabbed the least expensive one, and the 6 inch. She is a medium sized dog with razor teeth, and these work great.

Not recommended for the aggressive player..
Size: 6 Inch, Color: Red, Size: 6 Inch, Color: Red
First this ball was not delivered when it should have been. Second, the tabs are poorly made. One day of my dog playing with it and the tabs are already torn up. The ball itself is fun for her and has not deflated for now at least.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

My puppy’s favorite
Color: Orange
Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage.
Is colorful and my become my puppy’s favorite.
