Decent ball
Color: Blue Puppy, Size: Medium Size 2
Context: I have a busy, anxious Corgi. I like that it came with a pump to air it up. My dog likes the tag feature on it which made the ball easy to carry. She chewed off the tags pretty quick. She didn’t like herding this one as much. She prefers herding a basketball over this ball. The ball sits in the backyard through all the weather and elements and has held up pretty well. We’ve had it about a year and it’s still a good toy.

Easily Ripped apart within minutes
Color: Blue Puppy, Size: Medium Size 2, Color: Blue Puppy, Size: Medium Size 2
I have a new foster who’s only 35 pounds not an aggressive chewer and loves to play with my dogs rooster soccer ball toy but the ball itself is a little big for her to get her teeny little mouth around when she’s trying to carry and run with it this happened to pop up on my feed a size smaller (medium, instead of large ) and available for next day delivery, so I bought it specifically for the little dog to play with. I gave it to her to play outside while my hound is busy playing with one of her toys I went about watering the garden, when I turned around a few minutes later, I saw the ball appeared to be completely flattened. As I walked over, I saw pieces of black rubber on the ground, and then the rest of the ball had a gaping hole in it. The rooster version of the ball that I bought from another seller has been going strong for months with multiple dogs playing with it and chewing on it and ripping the side ribbons apart so either I got a defective toy or the quality of manufacturer from this seller is much lower since the durability of the ball seems to be less than an hour.

Not very durable
Color: Blue Puppy, Size: Medium Size 2
This ball is cute and my dog loves tags. However he popped this ball with one bite to carry it…. Within 10 minutes of getting it. It should have a tougher exterior

Pup loves this!
Size: 6 Inch, Color: Red
This soccer ball is so cute. My dog loves to play with these. The straps are durable, easy to pump up (they come with a pump), good value for the money since they tend to last awhile, at least for us. The straps are durable but could be an issue if your dog is an aggressive chewer. They stay pumped up for quite awhile and just need to be topped off once in awhile to keep the bounce there. We keep them outside even in the winter and they do just fine. HIghly recommend as a good play toy.
