In Canada, many low-risk animal products are handled through a notification route for veterinary health products, with their own permitted substances and claim limits, while products fed as part of the diet can fall under feed rules and anything claiming to treat a condition is a drug. In the United States there is no animal equivalent of the human supplement framework, so products are assessed as food or drug, with state feed rules applying to many. The same formula can land in a different category depending on the species, how it is given and what the label says.
