The Central California SPCA says the unidentified woman was trying to perform a surgical procedure on a puppy when an animal control officer arrived.
The woman was also caring for an adult dog injured in a car accident a month ago. The woman told the Fresno ABC affiliate she has no formal veterinary training. She says she was trying to save the puppy's life.
As for the older dog, she says she did not seek vet care, but gave the dog human pain killers.
Beth Caffrey with the SPCA said, "Our officer's continuing to do his investigation so that way we can find out if we can pursue anything as far as charges."
The dogs are expected to be okay and the woman was not arrested.
