Emily is moulting and I’ve been gently going through her fur as she has a few knots. Now Emily is older she does not look quite so neat as she used to. Anyway I have noticed she has dandruff down her spine. No bald or sore patches but a few specks of what looks like flea dirt around, again no big patches but there is something going on and I don’t think it is speck of soil. I was going to buy a spot treatment but not sure if she needs flea or mite treatments so I rang the vets. They said it sounds like mites or walking dandruff and Xeno is the best thing to use but that means a visit to the vets and not a buy over the counter. Any suggestions. I’ve just lost my job and money is tight but I don’t want Emily to get the wrong treatment and get an infestation.
