Deceptive Advertising
There's a little bit of false advertising going on here unless you thoroughly read the description. There are three balls in the picture, but you are only purchasing two. Always read the whole description before buying!

Not the same rubber.
I just received these today. I already have two of the same size direct from the local pet store. The one thing I liked about them that made me want to buy more - my 13lb dog could chew on them all night and never leave a mark. The red one I received was as expected. The blue one I received was not made out of the same rubber. It was softer. We played catch a few times and it didn’t bounce the same. I looked away for 5 minutes and she had it already starting to shred. Not sure what happened but 1 of the 2 balls I was sent was not up to par, possibly defective.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.

Loved it
Color: Brown/Wild Duck, Size: Large, Color: Brown/Wild Duck, Size: Large
He loved it so much, he destroyed it so we ordered another. I didn't realize that you can stick an empty water bottle inside. Again, the first one didn't last long, but he enjoyed it
