Tough & fun!
Color: Betty Bigfoot
This is my puppy’s favorite toy. I’ve bought 4 in case he eventually finds a way to destroy the ball because he is a 1 year old super-chewer. That said, this ball is TOUGH! It’s taken severe abuse from our dog & we couldn’t be more satisfied.

Not as tough as they make it seem
Color: Buck Wild, Color: Buck Wild
My dog chewed it up and destroyed it in less than 4 hours. I have a GSP 8 month old. She’s definitely a super chewer but this didn’t last at all. The tail crumbled apart and she ate some of it.

This is a HEAVY Toy
Color: Buck Wild
This toy is HEAVY. Really good quality, but my dog hasn’t shown much interest. If you can find a way to get your dog to play with it, I’m sure it would last for awhile.

Barkbox Betty
Color: Betty Bigfoot
A lot smaller than pictured. Still like it. Durable. Dog likes to carry toy around. Dog is 70 lbs and a heavy chewer and toy has lasted.

My puppy loves this pig
Size: X-Small, Color: Pig
This pig is great! My puppy loves it. It’s fun to throw. It’s soft and furry on the outside with strong edges and very durable. We’ve had it 4 months while my puppy was teething and it’s as good as new. It’s adorable too! 5 out of 5 stars !
