Immediately rolled up under the sofa!
Size: 4.5 Set of 4
I was looking for toys that were durable, that our GSD puppy would like, and that would specifically NOT roll under the sofa every time he swatted at it because I’m tired of moving the couch every 5 minutes to retrieve another toy. This toy went under the couch within 5 minutes of opening the package. He doesn’t seem to enjoy playing with it as much as he does a regular tennis ball, it’s easier to throw far outside IMO (my husband doesn’t notice a difference). It’s not hard or soft, it’s kind of a combination of both with the knobby bumps on the outside. I speculate the bumps are part of what he doesn’t enjoy playing with. He is able to pick it up and carry it easy enough and when he does it squishes just enough for him to carry it, he’s 5 months old by the way. But the bottom line is this will likely become yet another “outside toy” in the sea of outside toys because if not I’ll be constantly fishing it out from under the couch!

Great find
Size: 4.5 Set of 4
I am actually impressed with these balls. Our dog is a very heavy chewer and literally can tear every toy up within a few minutes. I usually buy tennis looking balls from PetSmart that are a little bigger than an actual tennis ball that has a squeaker and they don't last long. After he runs around squeaking them for about 20 minutes he goes in destruction mode. He loves the squeaker but loves to tear the felt off then the ball is destroyed next. They are at least cheap but not really if he goes them so fast. I have to ration them out. I decided to give these balls a try after reading another review that they are good for heavy chewers. He has been playing with these balls for weeks and they are still going strong. None of them have been destroyed. Granted he would prefer the felt ones but my wallet prefers balls that last.

Indestructible Doodle ball!
Size: Large (Pack of 1), Color: Multi
If your dog chews threw every tennis ball and toy, chuckit rubber fetch balls are the only one! Our dog LOVES it, he digs it out and has to have several so that there are a few outside and a couple inside because he chews them when he's bored inside and chases them outside! You dog will love it. It's a great value, especially if you watch for sales. It's our go to fog toy!!

Dogs Favorite Ball
Size: Large (Pack of 1), Color: Multi
Great fetch ball! Super durable rubber that holds up way better than a regular tennis ball and has an awesome bounce. Easy for dogs to spot and perfect for endless games of fetch. Doesn’t get soggy or fall apart — definitely a must-have for active dogs!

Bounces good
Size: Large (Pack of 1), Color: Multi, Size: Large (Pack of 1), Color: Multi
My dog loves this ball ,,the ball is a thick rubber ,and is flexible that even my little dog can carry it in his mouth, it does bounce really good , I recommend this ball if your dog likes chasing after balls. If you have a fenced in yard I do not recommend bouncing it hard because it might go over the fence. UPDATE I have had this ball a few days now and my dog likes to chew on his toys and tear them apart, one time he had a tennis ball and he managed to tear it apart but this ball he has yet to tear apart,
