"Just have to say that I took the Busy Dog Ball challenge because I said to myself that 'my dog will definitely chew this thing up and have it broken in pieces in a matter of hours (like all the other play toys I bring home to her)!' I always love a challenge! Well, I must say that I was completely WRONG! My dog LOVES this ball! She plays with it every day and loves the rewards she gets for playing with it! It is so durable that my dog can't break it or chew it up! I have a 1-year-old Dalmatian and she is quite playful and rambunctious, and even she can't demolish it! She gets all excited when I tell her 'Lets go get your Busy Ball.' She knows exactly what we are about to do! It is a great thing to have when I have to do housework or something and I just can't play with her... she can just play by herself until I am done with my work! We tried another product like this one that was made of hard rubber and Daisy chewed it up within hours. But not this one! The Busy Dog Ball is the best!!! I have recommended it to all my dog owner friends!" —Judy Campbell & Daisy
"Just wanted to write to you to let you know that everything you said wouldn't happen to the ball, didn't happen to the ball! Buster Brown is our 18-month-old Bassett Hound (weighing in at 70 lbs.) who lives to destroy his toys. We have even bought Kongs and he has been able to chew through them too! You promised that he wouldn't be able to do it to your ball and you were right. We have three other dogs in our house. Of course, Buster doesn't allow anyone else play with the ball when it has cookies in it! I'm going to have to invest in three more balls so that everyone gets their fair share. You obviously know your product well and I will definitely pass the name and number of your company to my family and friends. We are all dog lovers in our family. Thank you very much for the great product!" —Mark & Stacie
