A woman was attacked and seriously injured on Monday by her male pitbull while she was feeding a stray dog.
Rescue workers in Nakhon Ratchasima received a telephone call asking for help about 2pm.
They gave first-aid for Supaporn Wangjulklang, 60, before taking her to hospital.
Ms Supaporn had been attacked and bitten by her dog and had serious injuries to her neck and right arm, and was bleeding profusely.
Ms Supaporn's husband said they had raised the male pitbull, which they called Nazi, since it was a puppy. It was now six years old.
He said his wife was giving a stray dog some sweets when she was unexpectedly attacked by Nazi, probably out of jealousy.
The dog's bite had been so strong that he had to use an iron bar to open its mouth and free his wife, he said.
