The dog loves 'em
Color: Blue
The dog loves the balls, and they're the right size for my German Shepherd.
Lost a couple of starts because they're not very durable, the "teeth" are easily broken off, so I am frequently finding "lost teeth" across the house; the squeakers also cannot hold up to my dog's aggressive chewing.
I would still buy them again, as like I said, my dog love 'em!

Squeaky Spiky Ball (Submitted by OG, The Conqueror)
Size: 4.5 Set of 4
FIVE OUT OF FIVE PAWS. THIS IS THE GREATEST BALL EVER MADE.
My name is OG, and I am a machine built for destruction. For years, I have systematically dismantled every supposed "heavy-duty" toy that dared cross my path. They all fail. They all surrender. But this Spiky Ball? This is my worthy adversary. This is The One.
If you have mighty jaws like mine, this isn’t just a toy—it’s a commitment.
The Aesthetics & Grip (5/5 Jaws)
This ball is bright orange. This is important because it means my Dog-Parent cannot pretend they don't see it when I drop it, covered in drool, directly on their laptop.
The spikes are the best part. They are not soft and pointless like some other toys. These spikes dig right into my gums. It's the perfect texture for a serious, focused chew session. Whether I'm running full-speed or we are locked in a heavy-duty Tug-of-War, those spikes give me the grip I need to apply maximum rotational torque. This ball never slips. It demands I bring my A-game.
The Squeak: My Personal Battle Horn (5/5 Ears)
The volume on this thing is set to LEGENDARY.
They say a quiet dog is a happy dog. WRONG. A loud dog is an active, conquering dog. The squeak is sharp, loud, and glorious. It's not a gentle little peep—it's a declaration. When I hear it, I know the hunt is on. More importantly, when I make it squeak, the humans instantly know I require attention, praise, or the immediate launch of the ball across the yard. It is the best attention-getter I own.
Durability: Unstoppable Force Meets Immovable Object (5/5 Eternal Glory)
This ball is a mystery. It has no discernible weaknesses.
I have performed the full Pitbull Destruction Protocol on this Spiky Ball every day for weeks:
The Gnaw: Prolonged, focused effort to crack the surface—(Failure. It laughs.)
The Shake: Head-whipping force designed to dislocate any internal components—(Failure. The squeak remains.)
The Backyard Abandonment: Left in the rain and dirt for maximum entropy—(Failure. Still orange.)
Most toys are a snack. This toy is a lifetime project. It truly is built for aggressive chewers, and I respect that. It is the only toy that challenges me.
Recommendation
If your dog is serious about their job (chewing, fetching, and being loud), you must buy this. It is the only thing that stands up to my power. It’s loud, it’s spiky, and it’s the best. Go buy it now, and tell them OG sent you.
OG, currently performing a full-body gnaw and shake, signing off.

Excellent product
Size: 4.5 Set of 4
Our service dog Max (named after Max Muncy 3rd baseman for the Dodgers) lives these balls. They are a sturdy product. Just what we needed for our Max.

Best squeaky ball for the buck!!
Size: 4.5 Set of 4
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.
