hello flipperj2b! in my opinion, best jud is to ask an expert -- the vet. They know more than us.. From what i have heard / know, a shih tzu will only shed 2x in its lifetime and it happens at 7 to 12 years old. as in grabe nga shedding ako gi mean ha..
but in your case, since naa flaking, pwede nga lacking iya natural oils which could be due to unbalanced diet, etc. etc. pwede pud nga naa sya nakaon nga allergic sya. etc. etc. etc.
so, with the big number of possibilities, best it to consult your vet jud. labaw na kung feeling nimo dili na sya normal shedding or flaking.. ooppss.. let me add, i have experienced pud flaking sa shih tzu nako.. but di jud as in grabe. then naa red spots. the vet said that i should keep the body dry jud kay it might be caused sa umog nga fur as shih tzus have double coats.. true enough, nawala ra sya after a couple of days.. so it varies a lot jud.
ask your friendly vet.
