My thoughts and prayers go out to the family.
We spent New Years Eve at a friends house, they of course have a dog. Their dog is a non - allergenic dong with hair and not fur. We gave Nathan some Claritin before we left knowing about the dog and I brought his asthma inhaler. I watched him play with the kids and run around and he seemed fine. Then a little while later I noticed that he looked like he was holding his breath or his chest was tight. I asked him if he was good and he said "yes" and I said "lets do the inhaler in just in case." He said "ok" and continued to play.
