Sturdy ball with pump
Color: Black/White, Size: Medium
Thick material so it won't pop so easy. Comes with a hand pump and 2 ball needles. Tabs for the dog to carry in his mouth. Although my dog bites the whole thing to carry. Savage loves it!

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.

Great Ball
Size: 6 Inch, Color: Red
Our Little Goldendoodle Loves this ball & I like that it has so many straps to grab so I'm not getting the slimy part. It does not come already inflated so make sure you or a neighbor have an air compressor to blow it up because even though it came with a little pump I can't imagine how many weeks I'd have been pumping that without noticing any difference.

Virtually indestructible
Size: 8 Inch, Color: Red
Long lasting ball for a large dog. Bought the first one a few years ago. Its been outside all this time, still full of air and was virtually impossible for my large dog to destroy it. The weather affected the surface so ordered a new one. This has outlasted all the other balls.

Great toy for larger dogs
Size: 8 Inch, Color: Pink
This is holding up pretty well with my Great Pyrenees pup. She was able to pull all of the tags off-but the ball is intact for several weeks!
