Great for training and play!
Size: Medium, Number of Items: 1
My German shepherd love this toy! Great to take on walks with you as light weight and can fit in your pocket. Stands up to the toughest of play. Great as reward toy for training in place of treats! We always have one on hand at home or out and about!

Great for big dogs
Size: Medium, Number of Items: 1
Our pup is now 15 months old (nearly 110 lb and still growing). We got this ball when he was 3 or 4 months old.
GOODS -
- Our pup fetches with extreme drive, and the rope helps him quickly snatch the ball off the ground (versus a tennis ball, in which we are worried he will go head over heels at times)
- Our pup also loves to play fetch in the water, and this ball floats great and again, the rope gives another point to bite onto
- The yellow color is easy to see, even in grass
- Our pup typically fetches the ball, and leaves the rope mostly out of his mouth. So, throwing the ball doesn't result in saliva-covered hands
- It's pretty easy to throw the ball 50', and possible to throw it 100'
- It doesn't roll/bounce, so if you are for example playing fetch on your front lawn and are concerned with a tennis ball rolling into the street, this one alleviates that issue
- Our pup is spoiled and has several balls. This is absolutely his go to ball. We have woken up in the morning before to see him standing next to the bed with the ball in his mouth, asking us to get up and play.
BADS -
- Occasionally when he goes to fetch it, he will step on the rope as he tries to pull up on the ball.
- We have gotten this ball stuck in trees multiple times. In fact, there is one stuck on the roof of our church from playing fetch on the lawn there. :-/ Not a fault of the ball, but if you start whipping it around like nunchucks, it might not go where you want.
- The near max you can through this ball is 100'. And since it doesn't roll/bounce, throw distance is throttled. We often play fetch in a local baseball field, and have no issue wearing him out with this ball. However, if you are planning on throwing a ball the distance of half a football field, you might want to consider something else.
SIZE -
- We purchased both the medium and the large. Even though our pup is huge and can fit a soccer ball in his mouth, he still prefers the medium. It's easier for him to get in his mouth and breath while running back. The medium is the size of an orange, whereas the large is the size of a grapefruit.
DURABILITY -
- We have gone through about 4 of these balls, BUT this is because we lost 3 of them. We believe he dropped one out of the car window while we were driving, one is on the roof of our church, and I forget about the other one. On the first one we had, the stitching behind the black tape was down to a few threads after about 5 months. Given duration we use these balls (every day) and the joy he gets from them, I feel the durability is good for the price.
- We do play tug with the ball at times, and no issues there
Enjoy!

Good but better options out there.
Good ball, but is a cheaper version of the Foamster sold online. The rope is cheap and comes apart, and can be abrasive to a dogs mouth. The Foamster uses a higher quality ball and are more durable and use grippy biothane straps rather than cheap rope. They are also made to order in the USA with lots of fun colors. Worth the extra money if your dog likes these balls.

Fun toy for fetch
Size: Medium, Number of Items: 1
Daisy loves this toy. I found it from her dog trainer, and it makes rewarding her with a quick tug of war and fetch really easy. Also it’s shockingly durable. It looks like foam, but she has not destroyed this one.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.
