Photo is just for size comparison. It’s really hard and not chewable but he’s already put a dent into it, as you can see. Not sticky, smells right out of the packaging !! We loved that! Its size is about a 20 oz Powerdrink but it’s sturdy and heavy. It’s going to last us such a long time . The only thing is the logo might be worn off sometime soon. Go birds! 🦅

Perfect puppy toy!

Color: Pig Balls

The best puppy toys! These will have your pup happy as can be and well worth it! They are extremely loud so fair warning but bringing joy to your dog makes it worth it. Durable for a dog who doesn’t destroy things. Size of a clementine
