well shes smooth atm but it can all change really fast when they grow a bit, no way of knowing is there, though i have heard that if they have whiskers they will be rough or broken coated...doesnt matter as long as its a good quality coat. probs be around the same size as the parents since they arent too different in size. my advice is to have fun with her and dont start her too early, be patient, you can ruin a good dog by starting it too early despite what people on here might say. safest bet is a year, but you could go for about ten months if the growth plates arent still showing much. :wel
