Went to do barn work this morning and my 7 yr old mare has an knee injury. It wasn't bleeding and cannot see where it bled out (just got 20cm snow) After I washed it out it appears that she cut the skin off the knee (blunt force type of cut) it's the size of about 4"-5" long. Because the cut is long the skin is not together but it is all there (if that makes sense) She is happy and walking around like normal, she is bending her knee, no limp. It does not look like it went deep enough to injury or fracture anything. I washed it up and sprayed blue spray on it. The question is:
Should I try to wrap it? Or just let it be and keep the spray to it?
What should I look out for if there could be a problem?
