Update: I'm still battling the itch. The Malaseb shampoo came in and washed her but I think it may have been too harsh on her skin - it's very drying and I think the dry skin only made the itching worse. Her front paws seem to be doing pretty good now but she licked her back legs red and raw 2 days ago and started a gross puss-oozing patch in the wrinkles of one of her hind legs. I cleaned it with peroxide then malascetic otic solution then iodine and coconut oil. Finally wrapping it with gauze and covering with a bandage to keep her from licking it has stopped the puss. I'm going to wash her legs regularly with sulfodene shampoo - not as drying and seems to ease the itching.
She's also started itching her stomach and neck and opening little hotspots. The skin of all 4 legs and her chin are still rather red.
At 8 months pregnant this is so exhausting. I'm still questioning myself if I am feeding her right. It has been a little over a month on raw feeding. Reading how folks switched their EB to a new food and all the skin problems cleared up I'm looking forward to it happening for me. But what is the time frame? How long do I keep at the hamburger before it is conclusive that she needs a different protein? I know if it's systemic yeast that is the root of it that it will take awhile to kill it but should the detox phase be lasting this long? If it's really allergies, am I needlessly tormenting her with food that she is allergic to? If I need to switch off of hamburger that means no more raw feeding - the town 'butcher' only does chicken, pork and hamburger and only stuff for humans - can't even get green tripe commercially here. More exotic proteins are very expensive to get here and I don't think I'm ready to take on raising meat rabbits or goats with my baby just 6 weeks away. So we'd need to switch to one of the good kibbles.
I have digestive enzymes and probiotic supplements on order for her to add to her food. Acv and yogurt may not be doing enough to improve her guts. I just don't know how long I should keep feeding her hamburger at this point, the itch is driving us both mad.
