Great squeaker balls - dogs favorite but not for aggressive chewers.
We have a chocolate Labrador retriever and a golden retriever who love balls. Tennis balls don’t last. We’ve been very happy with the ChuckIt quality. We especially love the bucket of orange balls those last until we lose them. We’ve tried to other products from ChuckIt and they’ve always been excellent. Squeaker toys are a special favorite in our home. However most don’t last because our dogs are moderately aggressive chewers. They haven’t destroyed these… yet. HOWEVER, we have a ball-obsessed, very aggressive chewer grand dog Sadie (“Ball Is Life”) who visits frequently. She goes nuts over anything that squeaks. She’s not satisfied until all squeakers are dead. And she destroy this ball in about 2 minutes. It’s fine when she supervised and we’re playing fetch. But when left on her own, she’ll find these balls and destroy them. We had 6 and in 2 days were down to four. I will still give it 5 stars because nothing is indestructible. And Sadie is an exceptionally aggressive chewer. On durability, these are above average maybe 7/10. But be warned, aggressive chewers will destroy them.

Durable except squeaker only works for a few minutes
My pups loves these balls mostly for the squeaker. Company dose not glue the squeaker in place inside of the ball so after a few chews from pup the squeaker pops out n bounces around the inside of the ball. Than after awhile the end pops out n that's a good thing for me due to I'm able to glue the squeaker back in place then glue end back also. Now the squeaker works again. Easy fix yet company should have done this before my pups played with them. Scary, what if my pups chew the ball n by chance chocks on the squeaker? I now take the ball apart when they 1st arrive n glue the squeaker n end in place the day before they play with them. Company should just glue the squeaker in place before they sell them to keep our pups safe from chance of chocking.

My dog’s all-time favorite toy!!
My boxer mix LOVES LOVES LOVES the Chuck it ball! It is seriously his favorite toy. I think he likes how much give it has when he chomps on it, kind of like a dog stress ball. It does squeak when chewed but the squeak typically goes away in about a week likely due to saliva getting inside the ball. It bounces really well, my dog loves to catch it mid-bounce. Nice smooth rubber, easy to clean. It is very durable, we’ve never had one that broke. We usually only have to buy more when they go missing. The size is similar to a tennis ball. I’ve also noticed there is a difference between the mostly blue chuck it ball and the mostly orange one. The orange one is harder than the blue. My dog can tell the difference and only likes these blue ones.
