Can anyone give me some helpful info about this? I believe Ava has this. Poor thing just itches and itches and she has got these patches on her belly, black dots almost. It's not raised but it's red. I put some of the Penetan Creme on it that I use for her lips and that seemed to help A LOT but she is still scratching like crazy. I bathe her with a flea shampoo and apply K9 Advantix, vacuum every other day not too mention just had my carpets steamed cleaned. I don't know what else to do for her. Should I try giving her a supplement in her food? Any thoughts and info from anyone else who has gone thru this would be greatly appreciated.
