Officers were initially told there were around 20 animals, but later discovered twice as many, mostly Chihuahuas, Pomeranians and crossbreeds, living in cramped, ammonia-filled rooms.
One cat was also found at the scene.
Rescue from ‘dark and airless’ rooms
Animal rescue officer Ellie Barnes-Wilson described the conditions as “dark and humid,” with the smell so strong it caused eye irritation. Many dogs were suffering from burns to their eyes and were found huddled in boxes or drawers.
The animals were removed over five days and transferred to RSPCA centres across Hertfordshire, Essex, Cambridgeshire and Norfolk.
Charity highlights lessons from case
The charity said the dogs were clearly loved, but the owner had become overwhelmed after failing to neuter two original pets, leading to years of uncontrolled breeding.
“This shows how quickly things can spiral,” said Ms Barnes-Wilson. “We urge anyone struggling to reach out before it becomes unmanageable.”
The case is now being used to promote the RSPCA’s Adoptober campaign, which encourages rehoming and responsible pet ownership.
