Foot rot
In foot rot, the horny wall of the digits may separate from the sensitive internal structures and the space becomes filled by dirt.
If your sheep are lame and on close inspection you see that the horn has separated from the wall of the foot and it smells rotten, the animal probably has foot rot.
If the infection is not stopped, it will invade the deeper tissues of the foot and may invade one or more joints, causing chronic arthritis.

Foot scald (or interdigital dermatitis)
Foot scald can occur when conditions are persistently wet underfoot, especially when the stocking density is high.
It causes marked lameness, it can develop very quickly and it can be so severe that the affected animal is reluctant to stand.
The skin between the toes can be either red and swollen, or blanched and white.
Sheep and goats are most commonly affected, but the condition can also occur in cattle and possibly other ruminants.
Affected feet don't stink like foot rot.
It is caused by a bacterium.
Animals can recover spontaneously if they are moved to drier pasture.

Foot abscesses
Foot abscesses develop between the digits or inside one of the digits.
There may be a swelling between the digits and/or the affected digit may be hot and very painful.
The abscesses are caused by bacterial infection, and they make animals very lame indeed.

Foot trimming is the first step in treating foot rot. Trimming the foot will cut away any cracked areas in the hoof and help to prevent the foot rot organism from becoming established. Sheep who have foot rot should be trimmed to remove all infected areas. It is extremely important to open up these areas so that the foot bath solution and air can reach the damaged areas. Unfortunately this may also cause some bleeding. Do not become alarmed at the sight of the blood. A small amount will help to cleanse the foot.
