Dog Skin Rash Has Moved to Underside and Legs

I first noticed a problem with my dog’s skin on Sunday. After a little research I realized that she had hives. Her fur was raised out in nickel and quarter size spots, as I looked underneath the fur to see her skin, I noticed red spots.

I gave her some Benadryl and an oatmeal bath, the spots and raised bumbs went away. I gave her more Benadryl yesterday morning just in case. When I came home from work she looked fine and was acting normal.

The whole time she has not been lethargic, acting in pain, or itching and scratching​. It was as if she had no clue there was a problem.

I didn’t give her anything last night as I thought she was getting better. This morning the rash has moved to her underside, all over her belly and inside her legs. It doesn’t look like the hives from Sunday.

I haven’t changed her diet or shampoo. She doesn’t have a big yard to run in so she gets walks in the neighborhood.

She’s never had a reaction like this before and her environment hasn’t changed.

I just bought K9 Advantage instead of Frontline because I heard Frontline hasn’t been working. I haven’t put the Advantage on her yet because I didn’t want to make the rash worse.

I did notice her bite at her leg as if she had a flea, but after looking through her fur I couldn’t find anything. Any ideas?

She is a five year old pittbull boxer mix.
