[quote name='kjauburn']There have been a high number of dog deaths do to choking from greenies. There is currently a class action lawsuit over them from owners who lost pets. If I remember correctly the company who makes them was just bought recently and the new owners are trying to due damage control, including changing how hard the product is, free samples, coupons, etc.[/quote]
Yeah, there has been some controversy surrounding Greenies. There have been reports of choking and more alarming that they do not break down in a dog's digestive tract. A Google search will reveal these. That said, we've been giving them to our dog for years and he loves them. The advice we received from our vet was to give them sparingly, as special treats, and to make sure that we're supervising him when he's eating them (which is good advice for any chew toy or treat you give your dog, as choking is always a possibility no matter the hardness or size of the object). He chews them up pretty thoroughly before swallowing, so I'm not too worried.
