Gillian Kocher, spokeswoman for the Pennsylvania Society for the Prevention of Cruelty to Animals, says 10 puppies and five adult dogs were removed from the unlicensed breeder in Quarryville May 24.
Kocher says three adult dogs were debarked by a pipe that was repeatedly pushed down their throats to damage their vocal chords.
Debarking or the devocalization of dogs is banned under Pennsylvania law unless it is performed by a licensed veterinarian using anesthesia.
The dogs are currently in the custody of the PSPCA where they will receive medical care.
An investigation into the breeder is ongoing.
