Never noticed this before.
I have recently been seeing deer in my back yard and in the woods about 20 miles away, on both occasions these deer have these spots on their back legs on their knee area.
At first I saw just the 1 behind the house I thought she was hurt.
Now i am begining to think it's something else but I don't know what.
The spot is round and looks bloody! (next time I will try to get a picture)
Any Ideas??????
