Hi, dont know if anyone else has had a problem with warts or moles on yorkies but Megan had a ugly mole on her back,could be a wart,it looks like a mini volcano,sort of built up round the edge and a indent in the middle. its about 1/2 cm in width and its seeping goo. Dont know what to treat it with. It doesnt seem to bother her at all but its on the back of her neck and she wouldnt be able top get to it anyway. Any ideas???
