The Humane Society of Missouri says six adult Mastiff dogs have been rescued from a home in Aurora.
Four of the dogs were found living in an overgrown back yard with no access to food and water, while two other dogs were in a house that was strewn with feces and urine.
Those animals also had no food or water and are severely underweight.
Some of the dogs are suffering from skin infections.
All of the dogs have been taken to the Humane Society's Best Buddy Pet Care Center in Maryland Heights, Missouri for treatment.
Aurora police were able to get a warrant for the property.
