The Collie Dog fly is an old Scottish fly pattern designed in the late 19th century. It was probably one of the very first, if not the first hair-wing salmon fly ever, to be deployed on a salmon river. Aluminium tubes are a good all round choice for a wide variety of conditions and water levels. For the best results and peice of mind we advise pairing this fly up with our leading Salmon Tube Fly Hook (code 3717106)
