Close friends among horses frequently stand close together, graze beside each other and spend a significant amount of time grooming each other.
In addition to confirming the friendship and increasing cooperation, mutual grooming has other purposes.
While mutually grooming, the horses remove mud, sweat and parasites from each other’s coats, reducing the chances of skin irritations and infections. In addition, the rubbing by the horses’ strong upper lip provides an effective massage, stimulating circulation and helping to distribute the natural oils in the coat.
For their overall sense of well-being, horses should always be able to physically interact with other horses. Mutual grooming is a natural behaviour which improves health, alleviates tensions and increases social cohesion within a group.
