Great ball but poor squeaked design
Size: 4.5"
My Rottie loves these balls. The ball lasts a long time even though he plays hard and chews them. My biggest complaint is the squeaker disconnects easily from inside the ball, the glue does not hold! We have bought many of these balls because eventually the area where the squeaker is attached comes away from the ball leaving an open whole that causes the ball to eventually developed a long crack at which point it no longer is able to be thrown nor is is fun for him any longer.

Well made and great fun for our Pittie
Size: 4.5"
My pittie loves these! They are way thicker than others. He has learned how to chew on the spikes. Seems like a good teeth cleaning too. Yes, the squeaker breaks! That is a great thing!! With his active chewing, that sound was driving us crazy after a while.

"Durable Fun: Pweituoet Heavy Duty Squeaky Dog Balls for Aggressive Chewers"
Size: 4.5"
Product Review: The Pweituoet 4.5” Heavy Duty Squeaky Dog Balls have been a hit with my dog, proving to be both durable and entertaining. Durability: These dog balls are impressively tough. My dog is an aggressive chewer, and most toys don’t last long, but these balls have held up exceptionally well. The heavy-duty material and spiked design are perfect for dogs who love to chew, providing both durability and safety. Entertainment: The built-in squeaker adds an extra layer of fun. It captures my dog’s attention immediately, and the squeak keeps him engaged for longer play sessions. The spikes also make the ball easy for him to grip and carry around. Size: The 4.5” size is ideal for medium to large dogs. It’s large enough to avoid being a choking hazard but still easy for my dog to pick up and play with. The size and weight are just right for games of fetch, too. Value: Given the durability and how much my dog enjoys these balls, they offer great value for the price. They’ve lasted much longer than other toys we’ve tried, making them a worthwhile investment for any dog owner with a tough chewer. Overall Verdict: The Pweituoet Heavy Duty Squeaky Dog Balls are an excellent choice for medium to large dogs, especially those who are aggressive chewers. They’re durable, fun, and well-sized, making them a great addition to your dog’s toy collection. Highly recommended!

Actually stands up to use
Size: 4.5", Size: 4.5"
I have a pitbull who is a toy destroyer. All those toys, even the ones that say tough enough for destroyers, never hold up. THESE BALLS ARE AWESOME! I bought the 2 pack of the 4.5 inch balls and they lasted a year. I literally am writing this review after ordering a new set. These are well worth the money and Ghost (my dog) loves them. Hes a 103lbs pitbull and his life mission is cuddles and destroying his toys... and these lasting a year of everyday use is friggin awesome. Both toys failed in the same way eventually. They gave out in a circle around the "squeker".

She chewed it up in less than 10 minutes. This is not for heavy chewers but dogs that like to actually play with their toys it would be great!!! I gave it a 3 because it worked for my other dog who likes to play🤘
