Oh that poor guy
. I would try Atopica ASAP! It's a life changer for so many allergy dogs...including my little Marcel who is only 4lbs - it changed his life during allergy season. He used to wake up at 2am just to lick/chew his paws bc he was so irritated. After Atopica, never happened again. He still may have a few breakthru symptoms once in a while, but they're mild and tolerable. Btw, Marcel has not had a single side effect from Atopica.
When quality of life starts being affected like w/ your kiddo, it's really time to try all available meds. You don't want him to be miserable like this.
