Excess Levels of Vitamin D in Dog Food
UPDATE, May 20, 2019 - The FDA is alerting pet owners and veterinary professionals about the expanded recall of 86 total lots of 33 varieties of canned dog foods manufactured by Hill's Pet Nutrition. More information, including all recalled products and lot numbers is available through the FDA's Advisory.

UPDATE, March 21, 2019 - Hill's Pet Nutrition announced on March 20, 2019 that it is expanding its voluntary recall of canned dog food products due to elevated levels of Vitamin D. More information, including the full list of recalled products, is available in the press release.

As a reminder, veterinarians who suspect that pet foods are contributing to animal illness should make a report to the Food and Drug Administration (FDA) through their Safety Reporting Portal or by calling their local FDA Consumer Complaint Coordinators.

Pet owners who think their dogs may be ill from eating food with excess levels of Vitamin D should contact their veterinarians.

UPDATE, February 1, 2019 - In addition to the dry food recalls described below, Hill's Pet Nutrition has issued a voluntary recall of select canned dog food for excessive Vitamin D.

UPDATE, December 4, 2018 - The FDA has created a centralized Outbreaks and Advisories resource that contains information for pet owners and veterinarians. This will be updated as they have more information. Please see FDA Alerts Pet Owners about Potentially Toxic Levels of Vitamin D in Several Dry Pet Foods for more information and updates.

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.

Veterinarians who suspect that pet foods are contributing to animal illness should make a report to the Food and Drug Administration (FDA) through their Safety Reporting Portal or by calling their local FDA Consumer Complaint Coordinators. For more information, please see "Information for veterinarians on reporting suspected animal food issues," published in the September 1, 2018 issue of JAVMA.

Pet owners who think their dogs may be ill from eating food with excess levels of Vitamin D should contact their veterinarians.
