His coat was matted with dried-up faecal products and other waste which had accumulated over time to form hard, compact pieces.
When they rescued him, he was found alongside another smaller dog who was also in a terrible state. The members of the animal rights organisation Humane Society think the poor pups came from a puppy mill or some other dog breeding centre.
A few days beforehand, the NGO had received a complaint about a "suspicious" house in Windsor. One of their volunteers hurried there to investigate, leaving a note on the door. About 10 stray dogs in very poor health were later found in the surrounding areas.
Melanie Coulter, director of the Humane Society of Windsor/ Essex, confirms that a total of 14 dogs resembling the black Shi Tzu were found abandoned in the same area during this period. They were all in an "extremely worrying physical condition" and have since been treated by the organisation's vets.
