We were over at a neighbors house outside and Nathan was playing in the yard. A German Shepherd dog from another neighbor came over and rubbed up against Nathan and he didn't touch him at all - the dog did sniff him. He also went into a neighbors house for a few minutes that used to have a pet but doesn't any longer. When we got him, I noticed Nathan's eye was watering and it swelled shut. So bad I didn't even recognize him, I rush to get some Benadryl and his allergy eye drops. It started to go down but all night he had a puffy eye.
What could it be an allergy to the dog or some say a bug bite?
