Updated at 9:05 a.m. – MCPD Animal Services Division Capt. Michael Wahl said three dead dogs were found inside the home. Veterinarians at a local animal hospital decided to euthanize another because of its severely emaciated and anemic state.

Wahl said the six surviving dogs, all shih tzu, were also found to be emaciated and anemic but were treated and are expected to recover.

Police and the Montgomery County Humane Society will determine whether there is any next of kin interested in taking the dogs before putting them through the adoption process.

Updated at 8:20 a.m. – Assistant Chief Scott Graham, Montgomery County Fire and Rescue spokesman, confirmed a woman was found dead inside a home in the 9400 block of Corsica Drive shortly after 11 p.m. on Tuesday night.

Graham said police are investigating the incident, but don’t believe the woman died from carbon monoxide poisoning. Animal Control did assist authorities by removing animals from the home.

Montgomery County Fire and Rescue has responded to a house on the 9400 block of Corsica Drive in Bethesda, where a woman and several dogs have reportedly been found dead.

The incident was initially thought to to be a case of carbon monoxide poisoning, but now officials believe the woman might have died of natural causes. Ten dogs were found in the home, we’re told — three are dead and seven are alive. The surviving dogs are now in the care of Montgomery County animal services personnel, and are expected to be brought in for emergency veterinary treatment.

First responders are describing the house as filthy, possibly as a result of hoarding.
