There still may not be a magic treatment to help you lose weight, but things just got a little bit easier...for your dog.

The Food and Drug Administration has approved a Pfizer Inc. (PFE) drug to treat obesity in dogs by reducing appetite and the absorption of fat, the agency said Friday

The drug, called Slentrol, aims to help the roughly 5 percent of U.S. dogs who are obese to lose weight, the FDA said in a statement. Another 20 percent to 30 percent are overweight, it added.

Slentrol is not for human use and will carry such a warning to discourage people from using the drug, the FDA said.
