A 38-year-old woman who allowed a choker chain to become embedded in her dog's neck has been fined $8000 in a Perth court after being convicted of animal cruelty.

Nicole Peta Easther owned a four-year-old male Staffordshire bull terrier named Dawg.

A council ranger saw the dog had a choker chain embedded in its neck and the skin surrounding the area was red and emitting an abnormal smell.

The dog was taken to a veterinary hospital for treatment where an RSPCA inspector noted about 4cm of the choker chain was embedded in the animal's neck and skin had grown over it.

Easther, a South Australian woman who used to live in Western Australia, was sentenced in her absence in Midland Magistrates Court and was also ordered to pay the RSPCA court costs of about $7500.

RSPCA chief inspector Amanda Swift said the animal welfare agency did not recommend the use of choker chains, especially for tethering animals.

"If people need to contain their dog for a short period of time, RSPCA recommends an enclosure with adequate food, shelter and water with appropriate toys and items to keep the dog occupied," she said.
