A Possible Attack

After I picked Nathan up from daycare we can home and walked outside, like we usually do. Steve was out golfing so it was just Nathan and me. We stopped to talk to a neighbor who has a dog and Nathan reached out and pet the dog. He didn't get saliva on his hand so I assumed he was ok. We finished our walk and then came in the house. Shortly after being in the house, Nathan was drooling and had lots of saliva, so much that he started gagging and chocking on his saliva. I called the Dr. and gave him some Benadryl. He was crying and I couldn't come him down. Couple minutes later he was fine, I really think he had an allergy attack from the dog. Just when I thought he was doing fine, we have a relapse.
