poor madge hope she gets better soon

Thought so, as i said in my post above. From the way you described them they sounded just like what my dog had. Its flea allergy dermatitis. One of the only things that treats it rapidly is the fronline combo.
If my CKCS picks up fleas, she will come out in lumps and bumps all over her, but especially round her neck and at the base of her tail. My SBT has never had a reaction to fleas.
Hope you get Madge sorted soon xxxxx

I also would say it soundas like an allergic reaction, personally I think you should take her to the vets, just to be on the safe side.

Hope she gets better!

Thanks everyone.I have frontlined her now.Kyektula if you read back a bit i did mention that i have taken her to the vets and told me it was a flea reaction.
