Doctors have been analysing our breath for signs of disease for decades. Now researchers say the process is set to become more widespread for pets.

Breath samples can be painlessly taken from larger animals like dogs using a mask. Tanks are used to collect breath from smaller creatures like cats.

Human samples have helped to diagnose everything from asthma to cancer.

Researchers say pet samples will help vets diagnose liver, stomach, digestive and breathing problems.

Horses, cows, pigs, dogs, cats, rats and mice are among those creatures who will benefit from the treatment.
