Saints definitely blow their coat twice a year. Rough coats are more prominent for the large chucks of coat, whereas smooths just have to be brushed really well. They all tend to shed all year round, but more so in summer. My "favorite" bitch is in heat right now, we are planning to breed her during her next heat, but we were going to breed her this heat until she blew her entire coat. We think she is getting in another adult coat at 2yrs of age. She is blowing everything, her top coat, and she has already lost her undercoat, except on her neck/chest, which looks funny. Just brush really well daily during the shedding time, and then weekly(smooths), biweekly(roughs) the rest of the summer/year.
