A puppy and kitten are lucky to be alive after they were pulled from a Gold Coast duplex fire and treated by paramedics on Monday.

Holden, a seven-month-old cattle dog, and Chip, a grey kitten, were in their Pimpama home alone when a fire broke out about 3.30pm.

Helensvale paramedics treat Holden the dog and Chip the kitten.

Firefighters rescued the pets, who were not moving, drowsy, panting and covered in back soot.

The two-storey duplex was "fully engulfed in fire", police said.
