I just ordered an Oster rake, 18 teeth course. Everyone in my Newfie group lauds this as the best rake ever. I've been using a more generic rake, which has worked very well for me, but I like to get more bang for the buck if possible. I was wondering, would this also be the best rake for Aussies, or would another model be better for them? They also have very thick double coats, but it's true that their coats are quite different at the same time. Any advice on choosing the appropriate rake?
