Spoke with the allergist

Pumpkin's 1st control was 3mm, which is the minimum to be accurate; the 2nd was 5mm. His reactions were 3mm or less. They'll probably retest him near his birthday, depending on his other reactions.
I accidentally had some dairy the other day, and Pumpkin's reaction is still loud and clear. Sigh. The allergist said to wait two months before introducing any dairy/soy/eggs again, and to only do a small amount of one and see what happens. We'll probably do blood tests at that point.

As for the dog allergy... we have the inhaler and we have another appt set for the 11th to further discuss what's going on. Basically, are we looking at asthma as well??? Zyrtec and his inhaler are our best bets for now. Thankfully, we live in a no dog/cat neighborhood.
