The U.S. Food and Drug Administration (FDA) issued a recall Monday warning consumers that at least eight brands of dry dog food may contain toxic levels of vitamin D.

The agency stressed that of the pet products recalled, only food products intended for dogs were affected.

The Mayo Clinic says vitamin D toxicity can cause symptoms such as vomiting, weakness, and increased urination. Extremely high levels of vitamin D can cause more serious conditions like kidney failure and can be fatal if not treated right away.
The FDA issued another warning around this time last year about dog treats, warning pet owners to refrain from buying store-bought bone treats that could break apart and injure pets.
