Cellulitis and my mare...?

Actually what you should do is talk to your vet and see what they say because there may be another medication that could help. Another thing you can do is alternate hot and cold wraps...the more you do this the better it would be. If you could bring her in for like a half an hour and alternate cold and hot it will help to dissolve the cellulitis in her leg then cold to help with inflammation. What ever you do let her out. The more she moves around on it the better it will be. Unfortunately cellulitis is a "standing" disease or problem. I hope that this helps.

Call the vet and ask for advice. No one knows better than the vet

Cellulitis is a secondary infection of the tissue just beneath the skin. It can develop after a minor injury, possibly a scratch that you did not see and that has gotten infected. It is very hot, swollen and painful and can cause lameness. The horse needs to be given a course of antibiotics, cold hosing, bute, mild exercise if possible, ie leading out in hand. Sweat wraps are a medical powder mixed with water and applied to the area, covered with plastic - such as cling film formed around the area, followed by a pad and bandage. The chemical reaction causes the area to sweat and helps to remove infection. It is left on for 12 hours and then given twelve hours off to breath and if necessary reapplied.

Definitely the vet will need to see it. The antibiotics should help and the quicker you get the horse started on them the better the prognosis.

I would not keep her in the stall as it will swell even more. Wash the leg off with the hose and then warm water and Hibbiscrub (an antiseptic wash) and examine the leg for the slightest sign of scabs or sores. Some horses get infections from the slightest little scab and if she has been out she might have mud fever.

If it is from mud fever then I would keep her in at nights, wash the leg down, grease where the scabs are and bandage all four legs.

The vet will give you something to take the swelling down.

My gelding developed cellulitis on both hind legs and had a major infection in one front leg due to a puncture wound there (he got tangled in some wire, we think). The vet put him on antibiotics. In his case, the first round didn't work and eventually he was given IV antibiotics. It took awhile for it to heal. Hopefully, your mare's case isn't that serious. I would call your vet, though, if you haven't already, just to make sure it's under control and isn't getting worse. Infections aren't something to play around with. You definitely want to keep it clean and dry (other than the hosing, of course). Find some sort of wound spray/ointment to put on it, but check with your vet first to make sure the treatment is actually working.
