His Allergy Attacked Him

I was a little upset earlier when i picked up my son from his school because his allergy attacked him. How? There's his classmate brought a puppy as his "Show and Tell". Good thing that the puppy didn't stayed there inside the classroom for a long time because if it did, it could have been worse happen to my son, he could have throw up there during the class, and i am sure they would panic and might call emergency for help. Of course i don't want that to happen and will receive a call from them that my son is being sent to the hospital, that would freak me out. I really felt bad for my son and i felt so sorry because i wasn't able to let the teachers know about it ahead.

He is very allergic to dogs and cats, he gets hives, runny nose, watery eyes and keep on sneezing soon as he gets near to those furry kind of animals. He loves to have pet but he can't just have it because he suffers his allergy when he's around with these animals. I feel so sorry for him. I should've told his teachers about it. There was this application form i filled up before the school started but i wasn't able to put his allergies in there because i was thinking of medicine allergies since that was the only that is being stated there. So now that his teachers knows about his allergy, i am just hoping that they won't allow their students to bring pets inside the classroom anymore.
