    Durable
    Color: Purple
    I bought this for my 80lb 1yr American Bully male,who has made it his mission to test all the toys his dad and I have bought. Now I have 3 other American Bullies, siblings 3yr old 2 females/1male, who did the same at that age and I mastered toy shopping or so I thought. Lol. My new pup loves balls and this is the only one he firstly can't fit completely in his mouth and can't tear it apart. He has tired!

    My Dogs Loved Them!
    Color: Purple
    My dogs loved these for playing fetch. They seem heavier duty than previous ones I have had. Beware of the incoming constant squeak sounds if your pup gets really into chewing it.

    Shockingly, good ball!
    Color: Purple, Color: Purple
    I have a Doberman. She is a ball and toy destroyer. She is the most obsessive retriever I’ve ever had. Her retrieving urge, and indefatigability, puts my golden retriever to shame. Because of this, we throw the ball all the time. She is primarily an indoor dog and we have to exhaust her energy and so throwing the ball is how this is done. I got these balls in an effort to try to find something that would last longer than a few days. I have now had these 2 balls for six weeks. They are both still alive! It literally blows my mind. When I bought them, we took bets on how long they would last. I gave it a week. I lost my bet. I got the extra large size. It’s perfect for the giant jaw span of a full grown Doberman. It squeaks, which is irritating to us, but what she loves. She can lay there and chew on it and still not destroy it. They’re very heavy ball and bounce, so you have to be careful throwing it in the house cause you could hurt breakables. Whoever said that these feel like they came from the dollar tree must have been talking about something else. They are thick and sturdy balls. UPDATE: it has now been THREE MONTHS and our Doberman STILL has not destroyed these 2 balls. We play with them many times each day. WORTH EVERY PENNY ADDITIONAL UPDATE: it’s now been nine months. Took this photo this morning. We still have the balls and have since ordered two more. She chews on it multiple times every day. There’s a little hole in it now and it doesn’t squeak anymore but it’s 98% intact and still essentially indestructible. These balls are worth gold.

    The dog loves 'em
    Color: Blue
    The dog loves the balls, and they're the right size for my German Shepherd. Lost a couple of starts because they're not very durable, the "teeth" are easily broken off, so I am frequently finding "lost teeth" across the house; the squeakers also cannot hold up to my dog's aggressive chewing. I would still buy them again, as like I said, my dog love 'em!

    Dogs love them!
    Color: 3 Colors
    Dogs love them! Larger than your average tennis balls, satisfying for my dogs to chew on, the squeak isn't too annoying, colorful enough I can find them in the bushes.
