Equine Preventative Medicine Checklist

Along with spring comes vaccinations and preventative care appointments for our equine friends. We all understand the importance of preventative medicine, but it’s easy to miss things, so we’ve prepared a list of what you should be doing with your horse to make sure they’re healthy and prepared for summer riding season.

Vaccinations

We will start with the easiest – vaccinations. Vaccine protocol for the spring varies depending on your geography and your individual horse’s exposure potential and travel schedule. Always consult with your veterinarian if you are going to travel somewhere new with your horse. Here on the Front Range, we typically recommend a 5 way (eastern and western equine encephalitis, tetanus, rhinopneumonitis, and influenza) and a West Nile booster as the basic starting place for spring vaccinations. For a more in depth discussion of the vaccinations we recommended in Colorado and why, see the blog titled Why are the Vaccines we give in Spring So Important Here in Colorado?

Deworming

Deworming used to be easy – give your horse a deworming paste at set intervals and you’re done. But research has shown that deworming is certainly not as straightforward as we once thought it was. There are several options and differing approaches to deworming, and whether you opt to use a classical “rotational” deworming, or a more targeted “Fecal Egg count” approach, spring is a time to think about how to protect your horse from internal parasites. There are pros and cons to different deworming approaches, and we have complete articles on both of these regimes listed below.

Dentistry

teeth

Although there is nothing tying teeth floating to vaccination, deworming or seasonality, most people (veterinarians included) like the convenience of combining all of the preventative medicine into a single visit. Spring is a critical time to have your horses’ teeth checked comprehensively. Tooth and other mouth issues can have a dramatic impact on your horses’ comfort, performance, and even lameness issues. Dental issues and questions like “Does my horse need a float?” are immense subjects and are covered in detail in previous issues of the blog.

Physical Examination

A good general physical exam is a good idea for all horses this time of year so that we (both owner and veterinarian) are assured that there is no need for an alteration to the diet or that some insidious disease process is slowly creeping in unnoticed. It’s also very helpful to have a baseline of your horses’ health so when changes happen they can be noticed, and dealt with, quickly. Summer is riding and show season, and a physical examination will ensure your horse is at the top of their game, making your time together enjoyable for you both. An important aspect of the physical exam that often gets ignored is a very brief (just a few minutes) lameness exam. Whether you have noticed that your horse is tripping a bit more, or he just hasn’t been evaluated, a check of his legs could be invaluable in finding a mild issue before it is a major one. If this is something you are interested in, be sure to let the office know when you schedule your appointment that you would like the veterinarian to spend a bit of time with a lameness evaluation, so that a scheduling issue doesn’t arise.

Spring Preventative Medicine Checklist

Below is a quick reference for when your vet arrives for spring tune ups for the horses. I have had clients use this little outline as a basis for questions they have for the vet when he or she arrives. We all fall victim to “I forgot to ask while you were here” questions! Happy trails and enjoy the beautiful Colorado spring!!

Quick Checklist for Spring:

  • vaccines – 5-way and West Nile Booster
  • deworming or FEC – which is better for your horse?
  • Dental – Does your horse need a teeth float?
  • General Physical including weight evaluation, diet discussion, old age changes (ie cushings), and lameness evaluation

Fecal Egg Counts and Deworming

As spring begins to show its face in beautiful flowers and new grasses, the parasite life cycle is renewed.  Warmer weather encourages larval maturation from fecal contamination in pastures. As these larvae mature they make the progression up the blade of grass and await consumption by a new host.  As your horse grazes on the fresh spring grass, transmission occurs. This is a very simple representation of a parasite life cycle. 

Fecal egg counts (FEC) have been a hot topic for many years now, and they remain the best way to monitor and treat for parasite infestation in our equine partners.  Performing a FEC gives us an understanding of what your horse is shedding at that time, and is a likely representation of what they are dealing with internally.  Understanding this, we selectively prescribe dewormer for that particular horse and their individual issues.  Two or three weeks later, we recheck FEC to be sure that the dewormer did what we needed it to do! 

In Colorado, it is not uncommon for a horse to show no signs of parasites in an FEC. Our unique environment of generally dry and freezing conditions helps to reduce the transmission of parasites in general, and many horses lack substantial grazing opportunities. But they certainly still do occur. 

Since responsible deworming of your horse is a bit more involved than it used to be, each case and circumstance can be unique.  If you have questions about your particular horse, the environmental conditions, or their potential for exposure, you should have a discussion with your veterinarian. 

Spring Time Tune Up For Horses

QUESTION: Is it time for spring shots?

ANSWER:

Warm days, green grass, tulips beginning to show, and the familiar buzz in the background are all signs that Spring is here.The first thought is, “it’s too early”, but sure enough, the bugs are here.Insects are powerful and efficient transmitters of disease.It is the threat of their annual appearance, which reminds us that is time to consider our horses and their “spring shots.”

The term “spring shots” can be a vague one.In general, we consider it the vaccinations which will cover insect borne diseases, as well as those communicable diseases that are passed from horse to horse as we start getting them out, and hitting the proverbial trail.

One of the more commonly administered vaccines for spring is often referred to as a 5-way shot.This label represents the 5 diseases that the vaccine is meant to prevent; Eastern Equine Encephalitis (EEE), Western Equine Encephalitis (WEE), Tetanus, Influenza (Flu), and Rhinopneumonitis (Rhino).This year you may also hear of a 6-way shot, which adds West Nile Virus (WNV) to the above vaccine.

EEE, WEE and WNV are all diseases that are transmitted by mosquitoes.These diseases most commonly cause a condition known as encephalitis, which is swelling and inflammation in the brain and spinal cord.Infection with these diseases can be life threatening and leave some horses with permanent nerve damage.

Flu and Rhino are diseases that we consider respiratory diseases most commonly.Like the flu and cold in humans, our equine companions can catch these viruses from other infected horses, sick or not.Also like humans, our horses can exhibit similar respiratory symptoms when affected by these viruses.Runny noses, coughing and fever are commonly seen when horses are sick from Flu or Rhino.

Horses as a species are also one of the most susceptible animals to Tetanus.Tetanus happens when the bacteria Clostridium tetani infects a closed wound.The disease can be fatal if not caught VERY early and is easily preventable with yearly booster vaccination.

Along with vaccines, there are a few other “house keeping” things to consider with your horses.Spring is a good time to remember to de-worm your horses.In the spring, we usually use a combination de-wormer.Combination de-wormers are an Ivermectin product, combined with another class of de-wormer called Praziquantel to provide coverage against any possible tapeworms.Having a routine dental examination to assess whether or not your horse is due for a dental float is also a good idea.

Spring is also a great time to clean up your pens (hopefully before mud season is here!) and consider how to best manage your horses to minimize exposure to insects.A good fly control program can improve the quality of your horses’ day to day life, as well as decreasing exposure to bacterial and viral diseases.Also making sure that there is no unnecessary standing water around to minimize the exposure to mosquitoes (for horses AND humans) can really decrease exposure of everyone to West Nile Virus.

By getting all of the preventative care and house-keeping tasks completed this Spring, you can focus on spending time with your horse, in the saddle or otherwise, and enjoy all of the nice weather that a Colorad
