Pup Loves It, Some Other Notes
Color: Orange
We've had this for about six months and my 75 lb, 14-month-old German Shepherd pup LOVES IT. Her favorite is "Crazy Bouncing Mode." In fact, she doesn't care much for the normal mode. She chews it a lot - even drops it in her water bowl at times - and it's still going strong. This is a great purchase. It's nice hands-off entertainment. Do know that it is heavy compared to a normal ball - if your pup likes dropping it on the ground like mine does, it will land with a hard "thud," even with the included sleeve. Hopefully you don't have downstairs neighbors. Also know that the cover that goes over the charging port is removable and your dog may choke on it if they chew it in just the right manner. Definitely only let the pup play with it while supervised. All in all, great toy.

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.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.
