My shepherd loves this thing. He is a true fiend for a frisbee or ball and this is his new favorite toy. He will carry it around just to do so, and that’s a new thing for him. It’s soft which is good for my poor hands, yet it’s durable and stands up to the tests he throws at it. It flies well and hasn’t warped no matter what it’s hit. No tears through any of the chewing yet either. Good size toy that gives hours and hours of fun for the most playful and silly doggos out there!
