Oh my goodness. My cane corso (15 mos) LOVES this ball. It’s easy for them to pick up because of all the little handles sewn into the ball. It’s easy to throw as well. The only thing is he likes to chew them off if he gets free time with the ball. The ball itself is very sturdy. highly recommend, and I’ll be ordering more. We play with this every morning and he’s so excited to take it outside.

zelda‘s “indoor” ⚽️ ball!

Color: Squeaky Green, Size: Medium Size 2 (6")

zelda loves her soccer ball - because of the fabric “tabs”, and the way she treats her toys, we keep it inside. she loves to place all of her toys and bones on our bed, after they’ve been cleaned. this ball is perfect and soft enough to throw it down our steps, where she will run down, retrieve it, and bring it back to the bed. it arrives deflated and comes with the pump and two needles - the pump is not the sturdiest and felt like it was not inflating, but after only having to reflate it once with a bit of air since receiving it ~5-6 months ago, it still holds up!
