Tips for heading into spring.

February and March are ideal for making some serious plans for the riding season ahead. Within no time it will be May and we will be in the middle of the competition season, and hopefully some good weather!

If you have planned your training schedules, assessed your training needs, decided upon your competition entries and set your goals and aims you should be on the path to a successful riding year ahead.

Planning a competition or training schedule can help you to decide what help and specialist training you need and will reduce the risk of injuries and poor performance, or overdoing it at the beginning of the season.

Why not try something new this season?

Have a think about what disciplines you want to try this season. Perhaps you fancy having at go at some long distance riding, western riding or side saddle. Why not take some time to check out a different aspect of equitation and give it go, you never know you might end up finding out you and your horse are good at it!

Check out our website links for extra information on riding associations.

How fit are you? This is another good question you should consider. If you have been busy mucking out all winter you may be feeling pretty fit, but how much have you been riding and are your muscles and body riding fit? If you are to have a good season ahead not only do you need a fit, supple horse but it is as important that you are fit and supple too.

Have you renewed your horsy memberships?

If you are like me you usually forget about renewing your membership to the local riding club, BHS or other association until you attempt to enter your first show, and then panic.

So before the panic sets in check to see if you have renewed the required memberships

Watch out for Thrush !

Thrush is a problem that can become a problem for our horses during the winter. It can effect horses who have been standing in all winter on soft bedding or been out playing in the mud.

It is one of the more common diseases of the equine hoof. But does everyone know what thrush is? How do you prevent it, or how do you treat it once it has set up shop within your horse's hooves?

Thrush is a disease of the foot that usually occurs within the frog and its sulci (the grooves next to and in the middle of the frog). The disease is characterised by a very soft frog and sulci. When the frog is picked out, a thick, black discharge is present that is easily removed from the sulci. There also is a characteristically pungent odour which once smelled, is never forgotten.

The disease is thought to be caused by bacteria. Usually thrush does not cause lameness if the disease stays in the superficial external and non-sensitive area of the frog. However, if left unchecked, the disease can extend into the sensitive tissue of the frog and make horses quite sore. They might flinch as you clean the sulci. If not dealt with Thrush can progress to a severe lameness that can be seen at a walk, much like a hoof abscess. The infection in general leads to degeneration of the frog. Thrush also can cause enough degeneration of the frog that portions of that structure have to be removed by your veterinarian or farrier.

Thrush is most commonly associated with poor management practices or conditions. It can be seen in horses which are allowed to stand in paddocks or stalls that are full of wet manure, or just in horses which do not regularly have their feet cleaned. However, this disease is also seen in horses who are well cared for and which are never allowed to stand in on dirty beds.

Thrush can also occur in horses, that wear full pads underneath their shoes. Full pads do not allow the hoof to be cleaned on a regular basis. As a result, shavings, straw, or dirt, but most importantly moisture, get trapped underneath the pad and stay there for six to eight weeks--until the shoes are replaced. As a result, this long-term exposure to moisture and bacteria sets up the perfect environment for thrush to thrive. Basically, horses are at risk for developing thrush in any condition where the bottom of the hoof is kept in a damp environment.

But horses can also develop thrush for other reasons. A horse who has been unwell and on a course of anti-biotic treatments can also develop thrush, a the body becomes run down and unable to defend itself against the normal daily invasion of bacteria.

How can you prevent thrush?
It's simple. Keep your horse's feet clean. Every time you groom your horse or before every ride, you should pick out the feet. Don't forget to clean the frog and the sulci--don't just remove the shavings or dirt trapped in the sole. This is an excellent practice not only for preventing thrush, but also in checking for any foreign objects that might have found their way into your horse's foot, such as nails or rocks. So, you can prevent several potential problems with one hoofpick.

Also, try to keep your horse's stable or paddock as clean and dry as possible. If you live in an area like I do it is impossible during the winter months to have anything short of a mudslide in your paddocks. But daily foot cleaning will help offset the otherwise muddy conditions and will go a long way in helping prevent thrush.

What do you do if you find the hallmark signs of the disease in your horse's feet?
First, clean the feet. Make sure you have removed as much of the black discharge as possible. Then, allow the feet to dry.

There are a number of commercial products that are available to help dry the feet and rid the foot of the infection. One example is Thrush Magic.

Other medications can be used such as a dilute hibiscrub solution or a tincture of iodine.

These solutions can be applied topically to the frog to help resolve the infection (watch your clothes; most of these products will stain them forever). Wearing gloves to protect your hands is a good idea.

Be careful though. Overzealous use of these products can damage the frog by drying it out too much. In addition, most of these chemicals are strong tissue irritants and are very capable of causing chemical burns of the frog and skin if used in excess.

The thrush may be long gone, but the foot remains quite sensitive from the chemical irritation of the treatment, so do use these products as directed and don't overtreat.

Also, avoid getting these products on the coronary band and soft skin area of the pastern. If you don't think you are making headway with the infection within a few days, or you examine the hoof and the entire frog is unhealthy or perhaps even loose, your veterinarian and/or farrier needs to get involved..

The diseased frog will need to be removed along with any other unhealthy tissue with a sharp hoof knife. If you are having trouble resolving the infection or if your horse is lame, please consult your veterinarian. He or she can confirm whether or not your horse has thrush and recommend further treatment if necessary. contact your veterinarian. There might be another problem brewing within the hoof.

 
WAYS TO HELP YOUR HORSE DURING THE SUMMER MONTHS
Linseed can help Relieve Symptoms of Sweet Itch
The Equine Research Centre (ERC) have recently concluded a study that indicates that linseed can relieve symptoms of sweet-itch.
Sweet-itch is triggered by the serum of tiny biting flies known as midges (genus Culicoides). The bites cause intense itching, skin irritation, and patchy hair loss in horses.
A study performed at the ERC demonstrated that linseed, fed as an oral supplement, can provide relief from the symptoms of allergic skin conditions. Linseed has long been recognised as a superior vegetable source of omega-3 fatty acids to treat many atopic (allergies likely to be hereditary) skin diseases in dogs. But while it is commonly fed to horses to improve the hair coat, the exact effect of these omega-3 fatty acids on the equine dermis (skin) is unknown.
In the ERC's double-blind study, six Icelandic horses with a history of sweet-itch (confirmed by a skin test with Culicoides extract) were fed ground linseed, or an equivalent amount of bran meal as a control, for 42 days. On Days 0, 21, and 42, the horses were injected with Culicoides extract, saline (as a negative control), and histamine (as a positive control, guaranteed to trigger a skin reaction), and the resulting reactions were assessed over a period of 18 hours. Horses on the linseed supplement showed significantly smaller skin test reactions to Culicoides serum after 42 days, indicating a less severe allergic response. The ERC team concluded that linseed as an oral supplement is well-tolerated by horses, has no adverse side effects, and has considerable potential as a treatment for allergic skin disorders.

This research is excellent news, as to date there has been little owners have been able to do for their horses other than to try and keep them away from the midges and use topical lotions to help with the itching. Linseed can be fed to horses in a variety of forms, in cake, as an oil or in powdered form, however it must not be fed raw as it is toxic, so must have been cooked before feeding.
HEAD SHAKING
It is a bright sunny day, you mount up, and as soon as you begin warming up your horse starts tossing his head and sneezing. The sneezing eventually stops, but every time you try to begin work, he tosses his head or tries to rub his muzzle. You get off and apply more fly spray, thinking it's just the annoying gnats and flies that are beginning to emerge, but the head tossing continues. You check your bridle and make sure the bit is in the correct place and not too tight--everything looks OK. The next day, you change bits. It must be your horse just doesn't like the new snaffle. Then your ride is the same--if not worse--than yesterday. Almost constant head tossing makes it impossible to train your horse effectively. Weeks go by, and some days are better than others, but you wonder what in the world is going on. This is a headshaker!

What Is Headshaking?

Horses shaking their heads might not seem like a big problem. Horses shake their heads all the time, usually while outside in the paddock or in their stalls in an attempt to avoid insects that pester their face and muzzle. So what's the big deal? Headshaking, however, is different. It takes on a whole new meaning when this behaviour is performed frequently, if not constantly, while the horse is being ridden, and nothing about this behaviour is normal. Headshaking is the act of the horse flipping its nose into the air, sometimes even shaking its head from side to side. This type of headshaking, the pathologic manifestation, also often involves rubbing the muzzle and sneezing. Not only is this behaviour irritating and uncontrollable, but can seriously hamper the ability of the horse to perform in many disciplines. Some horses even become dangerous as their headshaking takes on an obsessive and violent form. These horses might appear as if a bee has flown up their nose.

What Causes Headshaking?
This disorder has been reported to occur in horses for decades and as with most horse ailments there are several factors that can cause horses to shake their heads, and there is a list of differential diagnoses that should be investigated before you give up on your headshaker.
Until recently, many people gave up on their headshaking horses. There did not seem to be anything that stopped the behaviour, making it impossible to enjoy riding that horse. For many years, people surmised that headshaking was purely a rider or training problem, not a medical disorder. Some people believed that the headshaking was caused by ill-fitting tack (the bit or bridle) or a rider with heavy or bad hands jabbing the horse in the mouth. Still others believed it was purely a training problem of a learned behaviour--that the horse learned that if it shook its head, the rider would soon dismount.
As veterinarians began realising that this was a medical problem, one early theory was allergies or irritation by pollen or dirt inhaled in the nose, tickling the horse's sensitive nostrils and causing the horse to toss his head and/or sneeze. Treatments included placing some type of filter over the horse's nose in an attempt to filter out allergens and/or small dust particles. This actually helped some horses. Although this was a fine treatment at home, nets on your horse's head in the show ring usually doesn't result in ribbons!
Another theory tested was that tingling or some other odd sensation within the inside of the nostrils resulted in the headshaking. The tingling was thought to be due to inhaled particles, allergies, or some other unknown factor resulting in a sensation that caused the horse to shake his head. The infraorbital nerve was blocked with a local anaesthetic (just like nerve blocks performed on a horse's leg to diagnose lameness). The infraorbital nerve is present beginning at the infraorbital foramen (about half-way down the nose), and when this area is blocked, it desensitises the inside of both nostrils. The horses then were exercised outside--if the headshaking was greatly decreased or stopped, then they were considered a candidate for an infraorbital neurectomy. This surgery transected the infraorbital nerve, which resulted in a lack of sensation on the inside of both nostrils, and for some horses it gave relief to the headshaking. Other horses were not as fortunate, and the surgery was not successful. This procedure is not performed very often these days since a newer medical treatment has proven more successful.

What To Do
If you own or care for a headshaker and the behaviour persists despite fly control and properly fitted tack, you should contact your veterinarian. A thorough physical examination should be performed and the horse ridden so your veterinarian can observe the headshaking behaviour. Questions you should be prepared to answer include: When does the behaviour occur most frequently--while the horse is inside or outside? Is the headshaking better or worse on an overcast day or in an indoor riding ring? When did the behaviour begin? If the headshaking is chronic, did the behaviour resolve over the wintertime? In other words, does this seem to be a seasonal problem?
Based on the answers to these and other questions, your veterinarian will formulate a plan to determine the cause of the headshaking. Causes for headshaking include ear mites, ocular problems, fungal infection of the guttural pouch, middle ear infections, nasal and/or dental problems, and a disorder called photic headshaking.
Your veterinarian will go through the list of potential causes and determine which is most likely causing your horse to shake his head. Several procedures, such as radiographs of the head, endoscopy of the upper airway, an ophthalmic examination, or an oral examination, might be needed in addition to a good physical examination. Unfortunately, even if one of the above-mentioned problems is found, treatment for the disorder might not stop the headshaking.
Many veterinarians believe that horses with seasonal headshaking, or horses in which the headshaking becomes worse in direct sunlight, shake their heads for the same reason some people sneeze when in direct sunlight (called the photic sneeze). These horses are called photic headshakers, which means that direct sunlight causes the headshaking.

What Is Photic Headshaking?

There has been a great deal of research on photic headshaking in horses and researchers believe that horses shake their heads due to the bright light that causes an abnormal stimulation of some of the branches of the trigeminal nerve, which provides sensation to the face and muzzle. The light stimulation of the eye causes an abnormal stimulation of some of the nerves of the face and muzzle and results in actual tingling or even pain sensation in some horses, which causes them to violently shake and rub their heads.
The reason that these horses have facial pain resulting from direct sunlight is still unknown. One theory is that a previous facial injury has resulted in abnormal nerve transmission. For these photic headshaking horses, avoiding bright light, keeping them in dark stalls, even riding at night eliminates this behaviour completely. Other horses are helped by using eye protection in the form of a face net during the day.

What Can You Do?
So, you have a headshaker, and he does get better in indirect or dim light; riding him at night in an indoor ring does eliminate the behaviour, but you can't ride in the dark forever. For these photic headshakers, there is a treatment that might help. A drug called Cyproheptadine, which is a histamine and serotonin blocking agent, was administered to a group of 25 headshakers. This drug resulted in moderate to great improvement in 76% of the horses. Al-though it is unknown exactly how the drug worked to decrease the headshaking, it was thought that the drug mediated sensation in the affected facial and muzzle nerve branches, therefore decreasing the headshaking. If the name of this drug seems familiar, Cyproheptadine also is used to treat horses and ponies with Cushing's disease.
If this drug does work for a headshaker, however, the duration of treatment is variable. Some horses will need to be administered the drug indefinitely, while others will need only seasonal treatment. Furthermore, some horses will need to be protected from the sunlight in addition to being medicated. In any case, working closely with your veterinarian will help you to find the best treatment regimen to help your horse.
