Hi all. About a week ago I noticed Alice, my 1 year old Delaware, has a swollen area Under the left eye. Right eye unaffected. There is no drainage or crustiness into the eye itself and no redness of the eyeball. Just swollen underneath. I thought I would watch it, and over this last week it has not gotten worse, nor improved. It has stayed the same. Her behaviors, eating drinking and pooping have all seemed normal. How long should I watch and wait? Any thoughts?
