They’re sure to provide hours of entertainment for your dog.

Having an active dog as a pet can be rewarding, but it can also be a lot of work to keep up with them when you have other obligations. For this reason, it is important to learn how to tire out your dog during playtime so that you may enjoy the remainder of the day in peace while Fido recovers from his “fetch hangover.”

Kong AirDog Squeaker Tennis Balls are ideal for this purpose. You don’t have to worry about your dog’s teeth being worn down by this classic tennis ball because it comes with a squeaker insert. Your dog’s teeth won’t wear down the tennis balls, thus it’s best for moderate to mild chewers. The popular Kong tennis balls are on sale this month at PetSmart for only $5 for a two-pack. Don’t wait until the end of the month to take advantage of this sale.

The two AirDog Squeaker Tennis Balls are composed of a special non-abrasive felt so that your dog won’t be able to chew through them in a matter of minutes. One customer calls them “durable” and “tough,” and another says her dog’s “aggressive chewing” hasn’t broken the toy (though the brand says they’re suitable for light to medium chewers). As a joke, a third person said that the ball was “still in one piece” and not in her dog’s “stomach.” That alone is a victory in my book.

A other buyer said the toys are “not indestructible but last a long time” and were “great value.” Even if you get bored of playing fetch after less than ten minutes, the squeaker in the tennis balls will keep you entertained for much longer. “He plays with them for hours, I stocked up on them,” said another pet owner.

Other Kong toys are also on sale for less this month as part of PetSmart’s July sale. The same AirDog Squeaker Tennis Balls are available in a three-pack for $6, in addition to the Kong AirDog Football Squeaker Toy for $6 and, of course, the Kong Classic Treat-Dispensing Toy. Don’t wait to take advantage of these savings while the sale is still going on.
