My Dogs Loved Them!
Color: Purple
My dogs loved these for playing fetch. They seem heavier duty than previous ones I have had. Beware of the incoming constant squeak sounds if your pup gets really into chewing it.

Shockingly, good ball!
Color: Purple, Color: Purple
I have a Doberman. She is a ball and toy destroyer. She is the most obsessive retriever I’ve ever had. Her retrieving urge, and indefatigability, puts my golden retriever to shame. Because of this, we throw the ball all the time. She is primarily an indoor dog and we have to exhaust her energy and so throwing the ball is how this is done. I got these balls in an effort to try to find something that would last longer than a few days. I have now had these 2 balls for six weeks. They are both still alive! It literally blows my mind. When I bought them, we took bets on how long they would last. I gave it a week. I lost my bet. I got the extra large size. It’s perfect for the giant jaw span of a full grown Doberman. It squeaks, which is irritating to us, but what she loves. She can lay there and chew on it and still not destroy it. They’re very heavy ball and bounce, so you have to be careful throwing it in the house cause you could hurt breakables. Whoever said that these feel like they came from the dollar tree must have been talking about something else. They are thick and sturdy balls.
UPDATE: it has now been THREE MONTHS and our Doberman STILL has not destroyed these 2 balls. We play with them many times each day. WORTH EVERY PENNY
ADDITIONAL UPDATE: it’s now been nine months. Took this photo this morning. We still have the balls and have since ordered two more. She chews on it multiple times every day. There’s a little hole in it now and it doesn’t squeak anymore but it’s 98% intact and still essentially indestructible. These balls are worth gold.

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.
