The RSPCA is appealing for information from the public to help find those responsible for leaving seven puppies suffering from a severe case of mange on the side of the road west of Brisbane.

The puppies were found in the Forest Hill area near Gatton on Tuesday night by a member of the public.

All seven were suffering from a severe case of mites which has caused significant hair loss and scarring, and could have been deadly if left untreated.

The RSPCA has appealed to anyone who may have information on the puppies' potential owner or who may have witnessed the dumping to call 1300 264 625.
