A Wareham man is facing animal cruelty charges after officials said his dog was locked inside a house with a dangerously high amount of natural gas.

According to the Wareham Department of Natural Resources, Robert Proctor of 18 Martin St. left his dog in the house with natural gas “over combustible levels, rendering it an unsafe environment.” There was gas in the home because a stove was left on, but not ignited. Officials did not say whether the stove was left on intentionally or accidentally.

First responders arrived at the home on Oct. 21 after a 911 call. The caller reported that Proctor was seen wandering in traffic on Cranberry Highway with another dog, an unleashed Yorkshire terrier.

Officials said Proctor was being treated for unspecified injuries when he told authorities his second dog was at home. Proctor then gave officers permission to enter the house.

Upon arrival, Department of Natural Resource Officers found the home locked and smelled natural gas through a partially opened window. The Onset Fire Department was called and firefighters ventilated the house. Officials said the dog “appeared in good health and was active” after being removed. Both dogs were taken to an animal shelter uninjured.

As a result of the department’s investigation, officials said Proctor endangered the Yorkshire terrier found in traffic and inflicted “unnecessary cruelty” upon the other. Proctor “failed to provide necessary sustenance” for both dogs, according to officials. Proctor was also cited for violating the town’s leash law.

This is the second time in three months officials responded to 18 Martin St.

On Aug. 13, a car struck a tree and spun to a stop against the house. The car's driver, Delores Proctor, 61, then backed up and struck the house again causing significant damage, police said

She was charged with operating under the influence of drugs after failing several field sobriety tests and admitting to using prescription medication, according to police. Proctor was also cited for operating after license suspension and negligent operation of a motor vehicle.
