The Royal Kennel Club and University of Cambridge developed the Respiratory Function Grading Scheme (RFGS) to scientifically assess and grade the severity of BOAS.​

​

The test is simple and non-invasive, carried out by specially trained vets, and involves assessing your dog’s breathing at rest and after a short period of gentle lead exercise. Dogs are given a grade from 0 (unaffected) to 3 (severely affected).

​

Price: £70
