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.
