Hi I did have the same problem with Aiko when I left for vacation back in philippines and left my poor baby with her papa.lol.when I came back my poor baby had her hair all matt.I was so dissappointed with my husband,ofcouse,for telling me everytime he calls overseas that he brusher her hair daily.(mens little lies lol) so anyway,I tried a little trick,which i dont know if itll work on yours,but i did pour some baby oil on the matt and tried untangling them slowly by my hands and them brushed it soflty till its free from matt.(bathe her after)those hard ones didnt do any good so i just cut them my self,especially under the body,armpit? and in their behinds and legs.It wont show that much since their hair is long and will be covered by the rest of their hair.plus after,I took her to the groomer and just had her hair cut or fixed a little bit so ill look nice.(dont let them shave it)trust me,your yorkie will be fine.if it still wont work,just ask your groomer whats best for her hair.
