I am fostering a puppy who does this. I bought the Brake-Fast bowl after a rescue buddy of mine suggested it. It is wonderful! I had tried a ball in the bowl and she just took it out and started snorting her food again!
I bought mine from a person on Ebay...very reasonable compared to the prices I found online....and shipping was included:
BRAKE FAST BOWL Dish Stops Dog from eating food fast SM - eBay (item 130325696567 end time Oct-17-09 12:07:23 PDT)
Super prompt shipping....and she has 100% feedback!
Oh...and that bowl does not tip over! I am so impressed with it! Has slowed Isabella down!
