These are thicker than a regular tennis ball, but he still manages to chew through the ball. The dog that you can’t wear out loves her chuck it but continually loses the balls in the trees. The balls work even in the minnesota snow!

The chunk it rubber balls are not worth a dime anymore. Suggest kong balls - the ones that squeak - much more durable.

Each ball barely lasts 45 minutes of fetch with my aussie before it splits in half (not exaggerating). My dog shreds tennis balls in 2 mins flat. Every single one so far has cracked in half on the first day of real use.

The felt peals right off the ball. Once they break they become useless for the launcher. They break at the seams so quickly that they’re unusable.
