My dog loves these
Theme: 2 Pack, Size: Medium
My dog loves these balls. I would just keep in mind that large dogs will be able to chew them and rip the ball apart due to design. Just something to keep in mind if you have a chewer. Great that they glow in the dark. Fun for dusk or night time ball

Good for playing catch with dog in failing light.
Theme: 2 Pack, Size: Medium
Several pluses with this product. On start, the downside for some is shorter distance throwing wiffle ball effect. Now the very good points. Glows from UV light exposure for dusk, second part is easy for dog to breathe when running around with it. Works with the Nerf lighted launcher also with it it "charges" them up along with the "Chuckit" handle. The original one for the Nerf one lasted 3 throws before busting. . . Belgian malinois so no surprise. I'll definitely be ordering more in the future.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.
