Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Hyper Pet Tennis Balls for Dogs: Because Every Dog Deserves to Play Fetch Like a Pro
Color: Green, Size: Regular 2.5" - 12 Pack
If your dog had a bucket list, fetching tennis balls would probably be near the top. And if that’s the case, then the Hyper Pet Tennis Balls are their VIP ticket to Fetch World. These little balls of joy are the real deal, perfect for small breeds that are living their best life chasing after something that probably doesn’t need to be chased but is just so throwable. The 12-pack means you can never lose a ball again...unless, of course, it gets lost in a mysterious “dog dimension” where all the socks go. These 2.5-inch tennis balls are the right size for those dogs that aren’t quite large enough to play with the big leagues. Think of them as the perfectly sized appetizer for the full-on Fetch Feast. Plus, they’re made from non-toxic material, so your pup can gnaw on them all day without worrying about a tummy ache (unless they’re overzealous and gobble up the whole ball...don’t worry, I won’t judge). If your dog doesn’t love fetch yet, they will after these balls come into their life. They’re designed to be durable enough for constant chomping while still offering that classic “bounce, roll, and fetch” action that gets dogs going. Pros: • 12 balls = endless fetch sessions (until the dog gets tired, but let’s be honest, that’s probably never). • Perfect size for small breeds—no choking hazards, just good ol’ fun. • Non-toxic materials for guilt-free playtime. • They squeak. And we all know that squeak is like doggy kryptonite. • Durability means no more fetching balls that break after three tosses (we’ve all been there). Cons: • They might not hold up as well with very heavy chewers (but don’t worry, your dog won’t know the difference until they’ve already swallowed half of one). • They don’t come in tennis-ball-flavor. If they did, I think we’d all be out of a job. If you’re looking to upgrade your dog’s fetch game (or just keep them entertained while you catch up on your own Netflix binging), these Hyper Pet Tennis Balls are a solid choice. Plus, your dog will be too busy fetching to judge your questionable snack choices.

Prefect for smaller dogs to play
Color: Green, Size: MINI 1.75" - 12 Pack
The only balls my sato mix will fetch! They are a bit smaller than regular balls and are more comfortable in my dogs smaller mouth (she is about 20 lbs). Great bounce and durability, highly recommend!
