Summer Sores on my Maisie Donkey


Hello... For the last 8 weeks, I have been battling sores that will not heal on the front of my donkey's rear leg, just below her hock.  On Sept. 15 they cultured positive for EColi, Staph, and Strep.  We have been treating them like traditional leg wounds with 2 debridement's done, but I am now tuning in to them possibly being Summer Sores (aka Jack Sores) having now learned this condition is quite common in donkey's and mules.  The situation has been complicated because two vets and I have not had any luck with getting a traditional bandage to stay up over the wounds. The wounds are in a place where she is constantly lifting and flexing her leg.

After doing a Search of ECIR Messages on this topic, would greatly appreciated hearing more about what may have worked for others who have dealt with this condition.  I just did a deworming with Ivermectin, and am trying topical .5% Ivermectin on the sores in hopes they may respond better to this than the Manuka Honey I had been using previously.

I will be updating her case history to show that I did increase Maisie's Pergolide dose to 2.5 mg per day on September 3rd.  I very much appreciate your insights and feedback.  Kindly let me know if you would prefer that I take this to the Horsekeeping group.
  Thank you, Sally and Maisie

I have not had to deal with this particular problem, but I did have to wrap a hock after surgery for a ruptured bursa for several weeks....So, what they did was do a figure of * wrap with gauze first, then a soft casting cotton sheet roll, figure of 8 and then vet wrap- figure of 8 again. Her bandage stayed in place despite lying down and flexing it.  If the gauze sticks to your sores, and you don't want to debride the skin, then wet the gauze with saline and it will fall right off. Oh and the figure of 8's where in opposite directions of the last wrap...hope that helps.

Dusty had summer sores under belly and down legs.I used Alushield, and Calamine in a spray bottle.  Alushield  worked good  but is expensive Calamine makes a crusty barrier which helps keep the flies off. It also dries out the wound, which  in Dusty'case help heal.

Thank you Trisha... The figure eight bandage that my vet and I were doing, that sounds similar to what you describe, created a raw sore at the top of her hock and the medicated pad directly on her wounds would always slip down her leg. 

While I dewormed with 1.87 paste, I used the lower strength formulation for human head lice topically after reading this study.

She is really uncomfortable now... constantly hiking up her bad hock in a "Knee Jerk" reaction. She may be remembering back to her sad days as a roping donkey. How much and how often can I give her Banamine, or another pain killer you might recommend, to help her tolerate the discomfort better?  While she has let me work on her leg without benefit of a halter or lead rope until now, yesterday she reached her limit and is now moving away from me when I go to do anything to her leg... 

Thank you,

Sally, this is an off-the-wall suggestion, but I've healed two major leg lacerations with amnion dressings.
They are somewhat flexible and are Super-glued around the edges to hold them in place.  One was near a stifle, but it still remained in place on a mare with 24-hour turnout.
The big problem for you would be finding a fresh equine amnion this time of the year. 
Since this is woefully off topic, contact me at canequinmorgans@... for more info if you're interested.

I have had to deal with summer sores on my IR Fjord mare. Are you using Elastikon tape? That was a lifesaver for me, as all of hers were either on the side of the knee or fetlock. I used a large telfa pad, then vet wrap, then taped the top and bottom of the vetrap. I think I was supposed to use gauze under the vetrap, but she wouldn't hold still. I had tried a variety of things like a magnetic knee wrap, bell boot over the joint, silver whinneys with tape, draping gauze affixed to vetwrap above it, and none were consistently covering. Keeping them covered was key; I put Neosporin on them and changed the bandage daily, but I'm not sure how necessary either are. Also, when Megan was down to one sore (finally) and being recently diagnosed with PPID and having trouble with her appetite, I tried APF. That last summer sore cleared right up! Not sure if it was the Prascend finally at the right dose or the APF.
