My standard poodle loves fetch, like loves it. He can play for hours. He has a wide selection of balls, like maybe 30 plus, all shapes sizes, and textures. I purchased this set, let me tell you. He is completely obsessed with the glow In the dark one. I am not sure why, maybe it is the texture or the bounce. But wow, he really loves it. He is also a heavy chewer. The ball seems very durable.While I got a deal on this set, the typical price of these aren’t cheap for something you are throwing a good distance. The opportunity to lose balls is high, especially if your dog chooses to not be a retriever. The whistling balls are kind of neat. The glow in the dark is nice at dusk. My dog’s favorite is the blue ball made of recycled materials.These are the best if your dog lives to play ball! My chocolate lab destroys tennis balls in a matter of minutes and these balls last until she misplaced them ?. Which brings me to the glow in the dark ball…… one of our faves!Excellent set, my dog starts running before I throw and tracks to the whistle from the ball. The newly updated glow ball is much better than the old one. It glows better and bounces better, they changed the formulation. My dog loves these, and looks forward to "Ball Time" multiple times a day.We have purchased these for years. THe rubber is sofy enough for the dogs teeth but sturdy enough to play on asphalt or concrete roads. The glow-in-the-daks ball is extremely bright once charged under a flashlight.We have a Golden Retriever that lives to play ball. These are so far indestructible! It’s been a couple months. We’re not buying any other balls.The pack of (3) balls were the same price as one at the Petsmart. My dog loves these balls, especially the one that whistles.All the dogs at the dog park go crazy for the orange ball (I’ve even had someone try to steal it) and my dog looves the glow in the dark one. Squishy enough to chew on but not chew through! Haven’t tried the blue one yet but overall glad I found these toys!Great balls for throwing. Our dog is a retriever so fetch is in his blood. With a tennis ball launcher these go miles so he gets a great workout. Normal tennis balls last one session and so far these haven't got a scratch. The orange whistling one makes a great noise and is easy to spot on grass, but the glow in the dark one is his favourite. It needs to be left near a light to 'charge' it up and once it's glowing it's like a glow stick! Definitely recommend these for active dogs who love fetch and get through normal tennis balls too quickly.The medium ones are about normal tennis ball size, so would fit in the less expensive versions of the Chuckit handle that come with a tennis ball.The balls are very robust, but I think he'd probably be able to chew them up if left as a chew toy (he can destroy a Kong) so these are reserved for fetch only.Really good set of balls, good quality, dog proof - if your dog loves and eats tennis balls you will know exactly what i mean. These are indistructable. the glow in the dark one is amazing and you can charge it by leaving it in the daylight or under a light, or even a torch, it is amazing as you can see it in the pitch black. They only downfall is they dont float, so if you are going near water buy the other chuckit ones, they are great for this as they do float. These balls above are really good for the park or the garden or forest as you hear them when they are thrown as they whistle as they fly through the air.Perfect for a medium breed. Soft orange & glow ones are preferred by our 9+ month female Vizslar as they flex for her smaller mouth. The blue ball is more rigid with some give & she will grow into it. Our spaniel likes the blue one, but prefers tennis balls. Our X L Old English Sheepdog would break the softer balls…. The blue one is only good for fetch with her as she would crush it if left alone. I would recommend these for all gun dogs including pointers & cocker spaniels. Medium is a good sized pack of balls & suitable for our girlie dogs. We have other balls from this brand & would recommend them all as they last (8years & counting for some)What can I say . I have an American Bully. He is just 13 month old.He destroys every ball hes had.Even solid hard plastic ones.These balls are brilliant and stand out better in grass etc. He loves these balls. I use the chuck ball thing . I mean these balls launch for long distances.Unreal excersise he goes mental for these balls. He walks home with one in his mouth, thinking he's the dogs NUTS.Bloke with a springer i see I've just ordered some for him. Like most dogs wreck balls in no time.Highly recommend these for ya hound.Or ya lass ( girlfriend ) them who play together stay together ❤ ?My Frenchie/Staff cross loves these and they LAST! We use the glow in the dark one indoors as it's soft. The holes make it safe and easier for him to breathe especially when he's running around outside.The whistle is also helpful to locate the ball (after losing one which came with the thrower).Yes they are expensive but I found them worthwhile, we still have all three and no damage from chewing has occured which is a win in my book. I will buy their products in future
