hot diggity damn, did THIS piss me off!! avaricious company refuses to recall dangerous dog toys:

basically it is called a "pimple ball" and it has one opening and a bell inside. this is also a choking hazard in the event the dog chews it up, but the bigger issue issue is that because there is only one hole it can get attached to the dog's tongue and be nearly impossible to remove. dogs have had to have their tongues amputated because of this, and the company has known about it since 2005 (!!!) all the while saying "that has never happened before" every time a dog got injured. they finally issued a recall in September, when this most recent incident happened in June.
so, don't buy crap from Four Paws pet toys, and tell your friends who have dogs to check for any toy with only one hole in it.
