Campaigners have released a picture of a cub discovered with a chain threaded through one of its hind legs.
A hole had been drilled through the animal's flesh after it was caught by poachers in south east London.
It is feared that fighting dogs are being let loose on the trapped animals either for "fun" or as practice for illegal fights.
The animal in the picture above - named Jingles by rescuers - managed to chew through the leather strapping on the chain and escape its captor.
Nets and snares have been discovered in wooded land in the Rotherhithe area of London, along with large zip-up laundry bags hidden in undergrowth.
And police are investigating reports of residents spotting gangs in the woods with iron bars and dogs.
The London cases follow reports in Livepool of gangs unleashing dogs on the city's streets to "tear up" urban foxes.
The remains of two decapitated foxes have been found there.
In London, a number of cats have also been discovered "ripped to pieces" in the Rotherhithe area.
