Indestructible ball….Destroyed my dog’s goals
Color: Brown
I have a golden retriever that would rather watch the world burn with every toy I’ve ever gotten him than play nice with any of them. He burns through toys faster than a cardboard bonfire. However, the trap was set…I bought this as a last ditch effort to show that four legged champion of destruction that he could be bested… I remember it to this day.. It was a Tuesday - raining The ball came in the mail and as I nervously unwrapped and opened it, it was as if he knew a new challenger stepped in the ring as he came barreling towards the front door where I stood. Not today I told myself as I stood with confidence with this ball of justice in front of me. The usual sit and stay kept him at bay until I tossed it to him in which he had turned into a frantic honey badger shaking the ball and chewing ferociously he wanted the squeaking thing inside that doesn’t squeak but sounds like an ugly cry. However, it is next Tuesday and the ball stands victorious My dog has been bested and now understands the chain of command. He respects the ball but will always come back for more until he feels that he has won All in all absolutely buy this for aggressive chews and toy playing dogs.

Broke the first day
I purchased the owl ball because of other dog chew toys I purchased from Amazon. Those other chew toys are still holding together. The main reason I got the owl ball is due to the different noises it makes other than the regular squeak noise. After giving the toy to my dog he loved it right away. He especially liked the noise it made. After a few hours, I noticed he was chewing a white tube-like device. I took this away from him and determined it was the noise maker in the owl ball. I examined the owl ball and noticed the glue used to keep the ball cap shut did not hold. On closer inspection, I noticed what looked like rubber cement was used to hold the cap on but if it was rubber cement it was used improperly. Anyway, I just reglued the cap correctly and now it's just a ball because my dog destroyed the noise maker. OK, Since I posted this review I was contacted by the seller. They offered to give me a full refund for the owl ball. I accepted the offer. So, I will try it again, but buy a different color owl this time. I never expected a refund since it's just a ball now, my dog still plays with it and it is holding up very well. The material it is made from is pretty sturdy.

Squeaker not working!
Color: Yellow
I'll give it 3 stars because I love the design and it's sturdy and great for dogs to hold/launch. That said, the squeaker doesn't really work... I tried everything but it just doesn't make any sound. My dog wasn't really interested but when it did make a slight sound he approached it. Once it stopped he lost interest. But he's very difficult to please😆 so if you have a normal dog, he'll probably like it! I hope the manufacturer fixes the squeaker issue because apparently many people are having the same issue, which is a shame because the product is clearly well made! I'm on the fence about returning it just because the quality it's amazing(squeaker issue aside)!

Sturdy rubber ball. Noise maker could be improved
Color: Red
I would have given it five stars because of how much, my dog loved it in the beginning. And shut us up holds true as a sturdy rubber ball. My only complaint is at with one of my dogs being a heavy chewer, she was able to bust the noise making part. The ball never broke open or anything. It just no longer makes noise. You can hear the piece rattling on the inside. The ball itself is still solid tho

POOR QUALITY WHILE OVER PRICED
Color: Brown
Like so many others said, the sound box in this ball is faulty. lasted ONLY for 30seconds. My dog loves the giggle ball I purchased prior so I knew she would like this as well. Well, she did, for that whole 30 seconds. Both of us were so disappointed we could not further our play. Plus this ball was so much smaller than expected for the cost. I would not have minded the cost had this ball been on the ball! Don't purchase this item. Buy the giggle ball instead if you haven't already. UPDATE... Ran across this message at a later date and I would like to thank the sellers at Mewlmart for their response and showing the best business practices as stated in their response below. ----------------------- We sincerely apologize for any inconvenience regarding your order and would like to offer you a full refund for your purchase. If you would like a full refund: please reply 'Full refund'. We hope that you give us another chance. Thank you very much. Best regards, Mewlmart ----------------------- Only thing is I wish I had seen their message earlier, as I believe the window of opportunity for a refund may no longer be applicable. But who knows, they may reach out and still honor it when they review this review. Will update if that happens as it is worth mentioning the extra mile they may take. I am sure I would just then turn around and buy another product from them, giving them another try:)
