I had found the large TPR Coated Tennis Ball in blue several years ago. My dog still has it. He loves to carry it around with him and put it on the edge of a chair and have it roll off onto his neck and if he bends his nose down it rolls over his head; if he lifts his head up, it rolls down his back towards his tail and he turns and picks it up before it hits the floor. He loves these and is so funny to watch. I have been searching for these for 2 years! Thank you for carrying them. I am ordering a back up set as well. Very happy customer and very excited "heavy chewer" dog.My dog loves these. They are both a little bigger than he would like, but he has fun with them! There is no way he will destroy these thoughMy puppy was able to shred the lining of the tennis ball. She loves it though!One of my dogs is an aggressive chewer who has an affinity for tennis balls which he destroys in minutes. These balls are proving durable enough to keep him entertained for days. Well worth the price.I have a puppy and heavy chewer. The puppy managed to skin the tennis ball without breaking the rubber, and my heavy chewer took care of the rubber outside coating. All of this happened within a week of getting them. Which is longer than other toys have lasted. But...I've a bulldog and he goes thru q lot of toys and tennis balls. I got something like this from the Dollar Tree but it only lasted for 45mins. This is my boys fave toy. It's so sturdy! I also like how it's dog friendly! We luv it!I gave it 3 star for durability as this is not my pit bull’s only toy. I know for fact if it was he would destroy it, as he has destroyed several toys to include tennis balls. But he likes his old toys because they squeak. He has already ripped some parts of the rubber off.My dog has a bad habit of tearing off the fuzz on the tennis ball so this helps prevent him from chewing the ball apart. Very sturdy and he still hasn't broken either one!My hoomanz got us these.They are majiks. Like my faveritz balz but with Speshul rubbery bitz. I luv them beyawned Imaginings! I plays and plays! I wags and wags and thens sleeps with thems in my mouths.Best weird ball things ever.
