You have to watch that your dog chews the Greenie well. If they are breaking off pieces and swallowing them, it doesn't get digested properly and it can cause a blockage.
Personally, I don't even bother with them anymore. Whenever I hear about a problem with a product I stop using it (there is even a warning about them on their website). Why risk it? There are a ton of treats out there dogs love and I brush his teeth and have my vet check/clean his teeth when needed. |
