Good for small breeds and fun!
Color: Multi Squeaker Balls, Size: X-Small, Style: 4-Pack
I’m glad I found these for my 6 month puppies they absolutely love them super fun to play with. Although, the surface has come off due to my puppies biting it off. Look at the sizes as they have a few!

👍🏼
Color: Multi Squeaker Balls, Size: Medium, Style: 4-Pack
This dog squeak ball has been a big hit in my home and keeps my dog entertained for long periods of time. The squeaker really grabs their attention and encourages play, tapping into their natural instincts to chase and fetch. My dog especially loves how it bounces and squeaks, making it perfect for both indoor and outdoor play. It’s lightweight and easy for them to carry around, even for quick games of fetch in the yard. In terms of durability, it has held up pretty well so far. The squeaker may not last forever with heavy use, but the ball itself still stays in good shape. Overall, it’s a fun, engaging toy that keeps my dog active and happy.

budget friendly for dogs who lose balls in the creek
Color: Multi Squeaker Balls, Size: Medium, Style: 4-Pack
Not great quality, but works for our needs. I have a ball crazy lab. She loves for me to throw a ball using the Chuck-it Ball Launcher. We do this in our wide back yard that butts up to a creek. At some point during her run and fetch, she will take a quick detour right into the creek. She nearly always still has the ball, but once in awhile it is lost. Not wanting to chance it on more pricy (and more durable) balls, I get these or something like these. They dont cost much, yet they do the job. I' not upset if one gets sacrificed to the creek waters and mud. Since the balls end up getting wet often, they will kinda fall apart over time (chasing, kicking, throwing, retrieving, dog saliva etc). But she doesn't chew on them. Glad she doesnt as tennis balls arent good on teeth, but even if it was ok, the balls probably would be breached easily. SO get these if you are like me and want a ball that does the job but arent a total financial loss if get lost or destroyed. For indoor play we and by we I mean our 3 dogs demand that we use the rubbery max glow chuck-it ball. And will ignore this style ball. Yes, I am well trained. lol
