Interesting theory, the inherited bit. I think it misses the mark, however. The epidemic of allergies in dogs is relatively recent, and it parallels the increased use of vaccines. The biggest predictor of allergies in my experience has been the owners who've followed the baseless conventional medical practice of annual vaccinations. Here's where you can read more about what many have been seeing for decades now, since vaccines have been severely overused, to the damage of our animals.
As to Apoquel, keep us posted. I'd be waiting for the other shoe to drop, if you haven't had problems yet.
