The FDA says vitamin D is an essential nutrient for dogs, but ingesting elevated levels can lead to health issues depending on the levels and exposure time, including vomiting, appetite loss, increased thirst, increased urination, and excessive drooling to renal (kidney) dysfunction.
The FDA reported that the affected dry dog food was distributed throughout the United States by prescription only through veterinary clinics and other select retailers with the ability to validate a prescription.

Pet owners who purchased bags of the affected product are asked to immediately stop feeding it to their pet and throw it away in a container where no other animals, including wildlife, can get to it.
