Today I noticed one of my Self blue seramas had a puffy eye. It has a little clear discharge that is coming out. Then a couple hours after I saw it a dog attacked the poor thing and put him into shock and gave a small puncture on his side. I cleaned his wound with hydrogen peroxide and then wiped it with a little witch hazel extract. I think it will be fine but I dont know about his puffy eye. He is really lethargic and sick now. What to do?
