Favorite balls
Color: Multicolor, Size: 6 PACK
I never thought that my black lab mix could enjoy a ball more than the slightly larger silicon (sp) ones we have used for years. The sound has her ears up from the moment I pick one up. Please not, these are not indestructible. Throwing them away once they break open (for heavy chewers) is best.

Dog loves these
Color: Multicolor, Size: 6 PACK
Perfect balls for dogs who chew the squeaker out. These have the felt going over the plastic squeaker piece. Super bright colors and perfect size for medium and small dogs.

So far so good!
Color: Multicolor, Size: 24 PACK
So far so good! Our Belgian Malinois/Black Lab mix goes through other brands of squeaky tennis balls in a matter of days. Including the ones that cost 2.00 a piece. Thrilled to see that the first one is still intact after a couple of weeks of play. She must squeak them if they are in her mouth so they do get quite a workout. I would highly recommend them.
