Pennsylvania Allergies

We're in Yardley, PA now and Ziggy's allergies have gone crazy again.  We have Banfield here so I was able to get him right in to a vet who had instant access to his medical records.  She's very nice and I like her a lot.  She put him on Ketoconazole but that wasn't enough to solve the problem so I had to go back and get him on an antibiotic.  I hate doing that but it's the only thing I can do to get this under control.  He was itching and biting and licking all thru the night and totally miserable.  I may have to reconnect with Dr Loops and try the homeopathic option again.
