‘Mudfever’ or Pastern Dermatitis

Pastern Dermatitis is caused by a weakening of the skin’s protective mechanisms. It can occur at any time of year due to trauma, wetness, parasites, immune conditions, liver disease and photo sensitivity. Bacteria can cause infection resulting in crusting scabs which are slow to heal, painful and can result in more generalised infections such as cellulitis (infection of the deeper tissues).

How Can I Avoid Pastern Dermatitis?

• Try to keep your horse’s legs clean and dry!
• Avoid overstocking and poaching of fields.
• Fence off gateways where the field tends to be most muddy.
• Stable horses for some of day to allow legs to dry.
• Brush off legs gently.
• Ensure mite treatment is administered regularly if the horse is susceptible.
• Barrier creams are best avoided.

How is Pastern Dermatitis Treated? 

Treatment depends on the inciting causes of the problem. A veterinary examination is advised prior to treatment. We may suggest clipping, cleaning, antibiotic and anti-inflammatory creams, oral antibiotics and/or oral steroids. Sometimes we will suggest further diagnostics such as blood tests, swabs and/or biopsies.
