The girls have got harvest mites I noticed they have been itching a lot recently - Pippa around her ears and Molly has been biting her legs/paws and has got red skin in her legs. I've checked for fleas, but didn't find any and put it down to an environmental allergy. I saw a post on the Labrador forum about harvest mites and it clicked... I checked Molly over and I found one of the little blighters... now I need to get rid of them... anyone got any tips? I've heard they are hard to get rid of.
