Kurri Kurri puppy killer Nathan Thompson has been banned from having anything to do with animals for at least 10 years.

After a night in custody, Thompson, 25, pleaded guilty to four counts of animal cruelty which led to the grisly deaths of nine out of 11 puppies.

He cannot now own, acquire, buy or possess any animal, or even be around another animal without an adult present, for a decade.

The order, made in East Maitland local court by magistrate Caleb Franklin, led to the removal by the RSPCA hours later of a pregnant dog named Sasha from the home Thompson shares with his girlfriend Sarah.
