I received my M-Ball and took it out of the bag. We have 3 dogs, 2 dachshunds and a corgi. The corgi and younger dachshund were completely taken aback by it, running away, barking at it, etc. The oldest (and smallest) dog decides to jump up on the couch, knowing it's a ball, and attacking it. The only thing she can fit in her mouth is the tag, so basically she's just pushing it around with her nose and paws when trying to dig at it. Funniest reception to a prize I have had yet lol
