UPDATE, December 4, 2018 - The FDA has created a centralized Outbreaks and Advisories resource that contains information for pet owners and veterinarians.

November 28, 2018 - Throughout the month of November, several brands of dog food have been recalled due to excess levels of Vitamin D. The most recent recall from November 27, 2018 involves three brands.

Dogs consuming elevated levels of Vitamin D can exhibit clinical signs that include loss of appetite, excessive thirst and/or urination, vomiting, drooling, and weight loss. Prolonged exposure and/or very high levels of Vitamin D in dogs can cause more serious health issues such as renal dysfunction.

The MSU VDL's Vitamin D Profile (test code 20035) includes an interpretation of results by a veterinary endocrinologist. When elevated levels of Vitamin D are reported, a potential dietary source should be considered.
