Comes with pump
Color: Colorful, Size: Large
My dogs enjoyed it but it’s not large dog proof. I have a husky and German Shepard…..the ball lasted a day before it was torn up. But this would be perfect for smaller or medium sized dogs.

Fun for my puff ball lover
Size: 30 Pcs
The gun is very cheaply made and sometimes shoots when the trigger isn't pulled. But my puff ball loving monster seems to love it and all his new puff balls. He was literally jumping with joy.
