Thanks for the fast replies! I was expecting something like a week, so quite happy to hear the short times in comparison to what I thought.  So far, a lot of hand washing and keeping her away from my face has avoided almost everything, save a few hives.  I will give it 48 hrs to be safe then bathe her again to remove any stray proteins from licking herself  (Did I mention she JUST got a bath before this whole thing started?)

Yes, and unfortunately I suspect that what is true with humans is also very likely true with other mammals-- that is, the time to full clearance is HIGHLY variable by individual.

Could be four hours. 

Could be more like twenty-four.

With people, I read that they need to eat a meal without the allergen for the original meal and allergen to be gone from their saliva.

Anyone know how long after eating one of my allergens my pup will likely have it in her saliva?  Long story short, she got a shrimp that someone dropped on the floor and now my pup who loves to give kisses needs to be restricted for a certain amount of time
