Both Schatzie and Annabelle receive Greenies about twice a week. Id probably give them more often but the cost is so high,

.
Im confused if it is ingredients in the Greenies that are causing blockage or if this could be caused by any ingested item like food, other edible chew items, etc.?
However, with all this aside...I am so very sorry for the loss of her Yorkie, this is very heartbreaking!
