Treating a burst heel bulb abscess?

I doubt it, many abcesses(and sores) give off foul odor. I would still leave it alone. Maybe put him on some SMZ's to fight infection but that's it.

The vet said that it's likely a secondary abscess trying to burst, and he put him on sulfa antibiotics. I'm supposed to keep wrapping it, but stop soaking it.

Should I be disinfecting the area with iodine? I've read that in a few places.

Thanks everyone for all the advice :)

Wow, I have never heard of a vet saying to wrap an abcess. The dryer you keep it the faster it will heal.

I personally would still leave it alone.

If you were going to scrub it, I'd use DILUTED betadine or castiles soap (available at most drug stores) which is very very mild. Just make sure that you rinse it well before you put the pad on it. Our vets always tell us to use animalintex pads dampened and scrub the are daily with castiles, and only soak it the first 2 days or so.
GL treating it:)

Thanks, I'll give it a shot :)
If I don't wrap it, then it definitely won't stay dry. On the West Coast it's still pretty rainy, and some parts of his paddock are still muddy. Unfortunately they're the parts he likes to stand in.

^The mud won't kill him. Chopper's happen in early spring when it was rainy and his was a HUGE abcess. Like, almost the size of a quarter. His healed within a week or so. :)
