Hi there. Thanks for the question
Hindlimbs especially are prone to developing cellulitis (inflammation of the soft tissue) even with small injuries. You are doing good things by keeping the area clean and such but more may been needed
If the wound is through the skin, it may be of significant benefit to bandage it
A standing wrap from the coronet band to just below the hock will also keep some of the swelling down.
I would also recommend systemic (oral or injectable antibiotics) as well as daily bute OR banamine for the next 4 days. You should see significant improvement with this
If she did get something caught around her leg, then there can be more soft tissue damage then is visible with the wounds...it is good she is not lame thought.
Im going to save this information and exit the chat since it seems you are not entering it.
Thanks for your help. If she did this probably last Sunday would it do any good to put her on antibiotics at this late of date? I do have her on bute so that is covered.
Thanks in advance for your reply.
