Do you feed your dog greenies? Dogs love 'em, but it turns out they are actually killing dogs!!! This Video is a news report on it, but the nutshell is that Greenies are now the 3rd largest cause of throat obstructions for dogs next to bones and fish hooks. Sad thing is it gets stuck in there esophagus, so surgery is the only thing that can be done if you notice in time. I know Guppy loves these things, but he definitely isn't getting any more!!!!!! His life isn't worth the risk!!
