Okay, so i took my lovely little Mee-kah out of town with me and we went to a home that had fleas. Mee-kad had 5 fleas which we took out and bathed her with Flea shampoo. I notied her flea bites started scabbing but read that it was normal. 3 weeks later (today) i went to bath her and noticed she has scabs all over the bottom of her neck, around one eye and the back of her ears. I am taking her to the vet tomorrow but can some one tell me what this could be? She has never had any kind of skin problem before and has been a healthy yorkie. I am so scared of what it can be. The week before we went out of town i took her to a new groomer and my inlaws are saying maybe she caught something there? Please help
