Kong Air Squeak テニスボール ミディアム

My dog usually destroys tennis balls in minutes, but this one has held up to a solid week of fetch and chewing. The built-in squeaker is perfectly loud without being annoying, and the felt covering hasn't started to fray at all.

The squeaker inside is loud enough to get my pup’s attention even from across the yard, and the fabric hasn’t frayed after weeks of heavy fetch sessions.

My dog actually caught this one mid-air and the squeaker still works perfectly after a week of fetch, which is way better than other tennis balls I've tried. The outer felt seems tougher than the usual cheap ones too, so it's holding up to chewing.
