Durable Fun for Chew-Happy Dogs
Size: Medium, Style: Squeaker
This dog ball has been a hit with my dogs, despite their tendency to chew through toys. These balls hold up surprisingly well given his chewing habits, which is why I keep coming back to them. They provide endless fun with their squeaky feature, keeping my dogs engaged and active. One thing I really like is their durability. While my dogs do eventually chew them up, they last a significant amount of time compared to other toys we've tried. The squeaker adds an extra layer of excitement, making playtime even more enjoyable for my dog. However, if your dog is an aggressive chewer, be prepared for some wear, tear, and replacement over time. The squeaker balls are worth it for the durability and entertainment they provide with the current price tag. They withstand a good amount of chewing, making them a reliable choice for medium breeds that love to play and chew. Just remember that they will not last forever.

Squeaks for a while
Size: Medium, Style: Squeaker
I've got probably 10 of these, now. The squeaker fails pretty quickly. But our dog still likes them, just not as much as when they squeak. I'm tossing these a good 75 yards and farther. The Chuckit glowballs make sounds through their holes so no separate squeakers there. Dog really likes those glowballs.
