If your dog loves tennis balls, you NEED these
Raising any puppy is tough. Raising a German Shepherd puppy has often left me questioning my life choices. So I was ecstatic the day that my 60-lb puppy decided that he loves tennis balls and occupied himself for 2 hours without needing constant intervention. Naturally, my immediate response was to make sure we had a constant supply of large tennis balls for dogs available. Now my puppy loves mischief, but he’s not an aggressive chewer. And I was irritated to discover that every brand and size of tennis ball broke within an hour max of play. By simply playing fetch and batting the ball around with his paws, every single tennis ball split into 2 halves. We needed something better! These squeaky balls are exactly that! They come in a 2-pack. I gave my pup the 1st one a week ago and it’s still going strong! We play fetch in the backyard, he brings it into the doggy pool with him, it rolls around in the dirt and can be rinsed off easily. It’s by far his favorite toy, and he takes it everywhere with him. Finally a squeaky ball that can keep up with my dog! These are the perfect size, texture, bounce, squeak, everything. These are the ONLY squeaky balls I will buy from now on. Five stars for sure!

Durable squeaky ball for chewers
Color: Blue+Red, Color: Blue+Red
These are great! My 54 lb GSP loves them and it’s the only thing she cannot destroy! She’s currently 1 year and we have had the balls for several months. We have this brand and similar ones too. They float, bounce, and squeak. The ridges are good for chewing.

Great squeaky balls
Color: Blue+Red
Awesome! My super chewers haven’t been able to destroy it. It’s been about 3 months now and it still squeaks and bounces like new! It’s a bit tougher than normal squeaky toys but so worth it for aggressive chewers.

Boredom Buster
Color: Green
This ball has been a boredom buster lifesaver. On the first day my 15 week golden retriever puppy played with it for a good 2 hours straight. I was nervous he would immediately get bored with it but nope, he searches for it every day. It has helped with his puppy teething, he's more likely to play with this ball than come up and use my hand/arm/clothes to teethe on. The battery lasts a good amount of time and is quick to charge but I did wish it lasted a bit longer. Overall I'm very happy. We live in a top floor apartment but the noise doesn't seem to be too bad for the neighbors. It's good quality and seems durable. Edit: The velcro for the sleeve wears out within a couple uses. It keeps falling off. It was my puppies FAV thing about the toy because of the pull tag thing. So now it's ineffective for him. Not sure if there's a way to get a new sleeve or not.

One of the best dog toys I’ve bought off Amazon in a long time
Color: Green
My dog Rosie is a heavy tower so it is difficult to find balls she doesn’t destroy quickly. I came across this item on Amazon and it is honestly one of the best pet toys I’ve ever bought on Amazon. After a long day of work sometimes I come home and Rosie has a lot of energy. I turn this ball on fast mode and she has so much fun. I do worry about how much shaking in her mouth. I don’t wanna give her a headache, lol but there’s also a slow mode that you can press for the ball to slowly move around, but it’s a really good toy and I’m happy. I purchased it if you have a heavy tower, I wouldn’t worry about them breaking it because we’ve had it for a couple weeks now and she’s doing great.
