Here is what the manufacturer had to say about it:
A response from Four Paws Products ....
"Thank you for your recent note expressing concern over the Four Paws® Pimple Ball with Bell. We were equally alarmed to learn that a dog may have injured himself while playing with this toy.
Dogs have been enjoying the Pimple Ball with Bell for more than a decade with over 500,000 units sold. In all the years this product has been on the market, this is the first injury of this nature that we are aware of. Unfortunately, accidents sometimes happen. That’s why we recommend that dogs always be supervised when they are playing with any toy. Of course, we also take great care in developing safe products.
At this point we have identified the problem and are not shipping any more Pimple Balls until all units are re-worked. We have contacted customers that carry this product and have asked them to return their inventory to be re-worked.
Thank you for your concern and feedback. Please know that we are in direct communication with the pet owner whose dog was injured. At Four Paws, happy pets and satisfied pet owners are our number one priority. Rest assured we will continue to work hard to deliver on our priority.
Sincerely,
Allen Simon
President, CEO
