My 8 year old Tennessee Walker has developed the irritating habit
of cribbing. Can you tell me why this occurs and if there are any long-term negative side
effects I should be concerned about?
Cribbing or Crib Biting is considered a behavioral stable vice.
The horse will take hold of an animate object with their incisor teeth (front teeth) and
by pressing down hard will arch their head and neck. They do this by contracting
sternocephalicous and sternohyoideus muscles (ventral neck muscles). This occurs in
varying frequencies depending on the individual horses need and desire to crib. Some
horses are easily
With the upcoming spring mud season could you tell me how to identify and treat scratches or greasy heel on my horse?
Scratches is a common term also referred to as greasy heel, mud fever, cracked heels all referring to a chronic dermatitis of the palmar aspect of the heel and pastern. Local irritation due to environment or trauma allow penetration of various organisms such as bacteria, fungi, mange, allergic agents and dermatophytes. Thorough dermatological workup including skin scrapings, biopsy, bacterial and fungal cultures is indicated. The condition is usually bilateral with the hind limbs affected more commonly. Pain, swelling, hair loss, exudation, and ulceration are common early signs. In chronic cases odor, fissure, vegetative growth and lameness can be seen. The environment in which the horse lives and locally on the heel (ie long haired horses) markedly predispose horses to this condition. Therefore the most efficacious treatment is to remove the horse from this environment. Often times clipping the hair and daily cleaning with a mild antiseptic shampoo will cure the condition. Larger lesions may require surgical intervention and or treatment with mild drying ointments that often contain a steroid for anti-inflammatory benefits. Culture and biopsy can also indicate topical and systemic antibiotics that can be beneficial. Severe cases that create exuburent granulation tissue (proud flesh), open wounds or sarcoids (tumors) need to be treated more aggressively with surgery, bandaging and hospitalization. Your veterinarian can offer these services and should be consulted early and regularly.
My horse has been lame for six weeks from a problem in the foot. My veterinarian has diagnosed a coffin bone fracture that continues to drain pus at the toe. We have been treating with antibiotics and bute, but the lameness continues to get better and worse at times. What else can we do?
It sounds like your horse as a sequestrum or dead piece of bone. This commonly happens secondary to a sole abscess or focal infection in the foot that secondarily infects the bone. The bone becomes weakened and fragments thus separating it from its normal blood supply. It then dies and sequesters with infection surrounding it. Small sequestrums can be absorbed or eliminated through the draining tract. Large sequestrums most often need to be surgically removed but, can occasionally heal back to the parent bone. Ancillary treatments include antibiotics, anti-inflammatories, and physical therapy (soaking and icing) as your veterinarian has appropriately prescribed. Complications if left untreated include laminitis, coffin joint infection, and hoof wall sloughing.
