You should talk to your vet about the scratching, your vet may want to try giving her Apoquel for allergies which may stop the scratching.

I personally would start with that shampoo, my pup has allergies, he was getting Cytopoint shots every 4 to 6 weeks. He was scratching like crazy this past Feb. or March, I bought the above shampoo, the first bath with it the scratching stopped. He gets a bath every other week, using this shampoo the scratching stopped and so did the Cytopoint shots until June when the pollen was really heavy.
Bathe her a few times using this shampoo, if she's still scratching I would speak to the vet about it.
