Poodles are supposedly 'non allergenic' dogs. When I was a kid, I had terrible allergies to animals (which I magically outgrew in my 20s), and the only animals I could handle were poodles and schnauzers. I guess they don't shed the same way, or produce the same kinds of dander (why they need to be groomed so often).

I wasn't sure how young the skin test works- I know that 6 months is when allergies just begin to rear ugly heads, and then 3 years for actual diagnosis and treatments. His head congestion could also just have to do with weather patterns- he was born in the spring, right? I guess he could also just have a cold- one of my friends in grad school had her baby in her 2nd year there, and daughter is now 3... that child is sick more often than anyone I've ever met. She must be building amazing antibodies!
