my 90lb Pit, LOVES these balls.. and they have been lasting for months!! The squeaker is ok, those are lasting a week or two.. but that's better than average for my guy. At $4 a ball in the 4 pack, it's a great deal for a dog that loves a new toy every month .. I give him one at a time, the 4 pack lasts for many months of fun.

Durable and Fun!

Size: 4.5 Set of 4

My dog LOVES these balls and barks with excitement when the box arrives. These balls are super durable and a great size that does not allow them to roll under cabinets and sofas.

Aggressive chewer squeaky ball

Size: 4.5 Set of 4

These are fun for about a day for my young Doberman. They tear and the squeaker gets dislodged inside the ball making it not so fun anymore. Have purchased multiple times bc they’re inexpensive but found one he cannot chew through now online Not for aggressive chewers sorry.

Spikey Balls Outlast Both Dogs!

Size: 4.5 Set of 4

Our two golden-doodles have destroyed many of the chew toys I foolishly invested in. I used to measure their lifespan and durability in a matter of minutes. Shredding toys seemed their delight and specialty. Squeakers were often attacked with spectacular ferocity as if they were tests of canine ingenuity to find ways to get to, swallow, or otherwise destroy the squeaker mechanism. That is until they met these spikey dog balls with attitude. Our girls delight in chasing them down when thrown and have wearied themselves trying to figure out a way to chew through them. These balls have broken the household record for longevity. They've taken a licken and continue to squeak and delight our girls. Which delights us! Safe, great value for the money, cute, and the color has proven tough through heat, rain, lots of aggressive chewing.
