 On January 5, 2007, the U.S. Food and Drug Administration (FDA) approved Slentrol, the first time the FDA has approved a drug for obese dogs.However, concerns have since been raised, since 2010, about adverse effects that might more strongly affect particular breeds.Dirlotapide (under the brand name Slentrol) was authorized for use in the EU by the European Medicines Agency for helping weight loss in dogs, but has since been withdrawn from the market in the EU.
