Care should be taken when selecting a harness because one style doesn’t fit all and some with ‘anti-pull’ features can cause pain. Many styles can impede the normal range of movement in the forelimbs too. Veterinarian and physiotherapist, Dr Marianne Dorn, recommends designs that have a Y-shaped front. These act mainly on the dog’s breastbone at the front of the chest to promote a calming effect and do not inflict discomfort.
