I gotta tell ya, I don't think she has/had seborrhea! I think she had a hard flea infestation! She has a very thick, curly coat. When she went to the groomer, I think she may have gotten razor burn and that aggravated her condition.
It's been a month since she was groomed, ten days and five shampoos with the medicated shampoo the vet sold me and I haven't seen her scratch anything but her collar and that's just occasionally.
I took her for a walk in the cemetery on Sunday morning. There was still enough dew on the grass to moisten her legs. Daisy has a penchant for fresh graves. She's not a zombie dog, but the peat moss mix they top off fresh graves attracts her like water melon rinds attract flies! She runs over the peat moss and then doubles back! Like she is sliding into second!
She got plenty dirty and seemed mighty proud of herself. She got another scheduled seborrhea bath when we got home.
Thanks again for your advice and concern.
