Australian animal health pharmaceutical company  Virbac  has voluntarily pulled its VeggieDent Chews off the shelves after they were possibly linked to several cases of mysterious illnesses in dogs.

A Virbac spokesperson said that the products in question were pulled as a precautionary measure and no causal link has been established for the VeggieDent product line, which is only commercially available through veterinarians.

This is the third petfood contamination case in Australia in the past six months. In light of the situation, critics of Australia's regulatory system overseeing petfood safety are calling for stronger measures to ensure the safety of Australia's dogs and cats.
