Dogs with a common allergic skin disease are taking part in a clinical trial to evaluate the effectiveness of homeopathic remedies for that disease.
Bristol University's School of Veterinary Science aims to settle some of the arguments about homeopathy versus conventional medicine.
During the trial dermatologists will make an initial diagnosis and then assess the response to treatments.
The aim is to find clear evidence for or against using homeopathic remedies.
Dr Peter Hill, senior lecturer in veterinary dermatology at Bristol's Vet School, said: "It is hoped that these trials will provide clear evidence for or against the use of such treatment in dogs with this disease."
