I saw the CNN report...and when they showed the vet pulling out that Greenies stuff from their intesines (sp?) I was shocked.
My thought is why chance it...like someone else posted I would rather just brush their teeth. The benefits do not out way the negatives in my opinion
And these were bigger dogs they were showing...imagine some of these small yorkies. The thought just scares me. I will not be buying them...too much else to choose from!
