Daphne is a 4 year old Shepherd Mix.  She presented with a deep pressure sore on one of her hind legs. 

Day 1 of treatment, first laser treatment.  The sore is open, moist, very swollen and one of the ligaments (the white thing) is exposed!

Day 4 of treatment, third laser treatment. The sore is significantly decreased in size and the swelling is almost gone. No more ligament poking out (that's a good thing).

Day 5 of treatment, fourth laser treatment. Almost completely healed; the opening is even smaller and healthy healing tissue is filling in.
