We have a Golden Retriever and a Gordon Setter; sweetest, gentleness dogs on the planet. But they have jaws that would rival a rabid Pitbull when it comes to toys!I have bought numerous falls for them in duplicate, so they won’t fight over one.30 minutes to an hour later, the balls of the past have been destroyed, demolished, ripped to shreds, de-fuzzed, in pieces, or worse, become a choking hazard!NOT THESE DURABLE BALLS!!! They have had them for a couple of weeks and the balls are going strong! These are so sturdy, durable, and washable! Our dogs love to make them squeak, which is not allowed obnoxious sound, they fight over one in a playful way. Try to take it out of each others mouth, bury it in the backyard, brought back in the house, covered in mud, and a quick walk to the sink, rinses off all the water and gunk that dogs get on things between dirt and slobber and grass.This will always be our go to dog balls. They even fit in the ball launcher!Price is slightly more than a tennis ball or two, but these are strong, and worth every penny! Truly, the best we have ever found!
