Natural Life Pet Products and Nutrisca, both of Saint Louis, are recalling certain dry dog foods because of the excess levels of vitamin D.

The voluntary recall was initiated after the receipt of three complaints from pet owners about viitamin D toxicity. The presence of excessive vitamin D resulted from a formulation error, according to the companies’ recall notices posted on the Food And Drug Administration website. Neither company provided product photos to the FDA for posting with the recall notices.

Dogs ingesting excessive vitamin D can exhibit symptoms such as as vomiting, loss of appetite, increased thirst, increased urination, excessive drooling, and weight loss. When consumed at very high levels, vitamin D can lead to serious health issues, such as renal disfunction.

Consumers should immediately stop feeding the following products to their dogs, according to the recall notice, and should contact a veterinarian if the animals show symptoms of vitamin D toxicity.

The recalled dry dog foods include:
