Don't deck the stalls with these holiday hazards

Bad holiday d├ęcor choices by equine owners can truly become a matter of life or death. (It's nothing to horse around with.)

Pet Poison Helpline

Everyone loves the decorations and lights associated with the holiday season, and most horse people are anxious to share them with their equine friends. Generally this occurs without problems, but to guarantee a safe holiday season a few items should be avoided when decorating barns or sharing food and treats. Peruse these holiday cautions on items that should be used carefully or not at all around horses.

Live greens such as pines and spruce boughs are generally safe when used in wreathes or garlands but should not be wound around stall bars or placed in an area where horses have easy access to them. Chewing on the stems and licking sticky sap may cause irritation to the mouth and gastrointestinal tract, and dried sap in a horse’s mane and tail is difficult and time-consuming to remove.

Yew (Taxus species) is an exception—cuttings in any form from this poisonous shrub should never be used in wreathes, garlands or decorations on stall doors, on fences, or in barns or pastures where horses might have any access at all. The Japanese yew (Taxus cuspidate), a common landscape shrub, is the most widely recognized yew, growing well in almost all parts of the United States, but other yews such as the English yew (Taxus baccata) and Canada yew (Taxus canadensis) are also poisonous. The dark-green needles and attractive fleshy, red fruit make it an ideal candidate for holiday decorations, but the needles and seeds, dried or fresh, are highly toxic to horses, dogs, cats, livestock and people.
Widely referred to as the “tree of death,” yew plants contain several alkaloids that affect cardiac activity. Collectively referred to as “taxines,” the toxins inhibit sodium and calcium exchange in myocardial cells, resulting in abnormal electrical activity and cardiac arrhythmias. The amount of yew necessary to cause toxicosis in horses is very small—estimated to be about 227 g (0.5 lb) for a 454-kg (1,000-lb) horse—and the onset of action is so rapid (generally two to three hours) that most horses are found dead next to yew clippings, wreathes or shrubs. Common signs evident before death include muscle tremors, ataxia, bradycardia, dyspnea and seizures. Sadly, there is no antidote and most horses die even when supportive treatment is provided.

Other plants such as mistletoe (Phoradendrom species) and English holly (Ilex aquifolium) are less toxic but should still be avoided. It is tempting to place a sprig or two of mistletoe over a stall door, but anyone wanting to kiss under the mistletoe should be advised to bring it to barn for the day and take it home with them when they leave. Berries are the most toxic portion of the plant, but all parts contain some amount of toxin. Signs of mistletoe poisoning are very rare but include colic, dyspnea, bradycardia, erratic behavior, muscle tremors and seizures. Mechanical injury from the sharp, pointed leaves of English holly may cause gastrointestinal signs such as hypersalivation, head shaking and lip smacking and ophthalmic irritation or corneal damage

Poinsettia (Euphorbia pulcherrima) plants have an overrated reputation as being toxic but are actually quite safe. They contain diterpenoid euphorbeol esters and steroids with saponin-like properties (detergents). The milky white sap released when the stem is snapped or cut can cause a contact irritation to the skin and eyes, pruritus, and hypersalivation or gastrointestinal upset, but the signs are generally short-acting and self-limiting.

Most artificial or synthetic decorations are safe to use around horses but need to be placed so horses with busy mouths cannot chew or otherwise ingest them.

  • Tinsel and ribbons, if swallowed, may result in esophageal choke, gastrointestinal upset, colic or an intestinal foreign body obstruction.
  • Homemade dough-type ornaments and decorations contain a moderate amount of salt and may be hazardous to smaller horses, ponies and minis that ingest more than one or two larger decorations.
  • Holiday stockings, especially those stuffed with treats and goodies, hung on stall doors, may be easily grabbed by a curious horse that would rather eat the entire stocking contents than enjoy the decoration. While most treats are not harmful, an entire stocking eaten rapidly may result in esophageal choke, colic or a foreign body obstruction. It is far better to hang all the stockings together in single location far away from curious horses with busy mouths.
  • Battery operated ornaments and decorations as well as loose batteries should be in a location inaccessible to horses. Chewing or swallowing a chewed or intact battery may cause irritation and burns in the mouth, an electrochemical burn in the esophagus, or an intestinal foreign body requiring surgical removal.
  • Decorating or dressing up a horse for plays, costume parties or just in good fun is not unusual. Care should be taken that these costumes do not have any loose buttons or objects that may contain lead or other toxic metals. As with all costumes, eyes and noses should not be covered and any body paint used should be listed as nontoxic.

Sweet treats such as chocolate and baked goods are generally harmless in small amounts, so there is no need to worry if a horse, even a miniature horse, eats a chocolate donut or small package of chocolate candies. The amount of theobromine, one of the toxins in chocolate, is harmful in larger amounts, so feeding more than a treat or two is not recommended. Visitors to the barn should be advised that feeding small amounts of any sweet treat, even crunchy carrots, may be hazardous to obese or insulin-resistant horses. Senior horses often have poor dentition and a high potential for esophageal choke, so all holiday treats including apples and carrots need to be broken into smaller pieces for them.
Caffeine-containing beverages are not especially harmful in small amounts, but beware the holiday punch made with ethanol. Horses are as sensitive to ethanol as humans, and spiked holiday punch is best left to adult humans and not fed to horses either as a treat or with malicious intent. Clinical signs of sedation, depression and incoordination occur within 30 to 60 minutes and may last for several hours, depending on the amount and concentration of ethanol ingested.

It goes with out saying that candles and other items that plug into any outlet should not be used anywhere inside the barn. While they are lovely to look at, the risk of fire hazard or electrocution is simply too high. Wiring on lights should be inspected each year before putting them up outside and kept well away from horses and other barn pests that may chew on the cords. Outdoor LED lights are safer and burn cooler, so, if possible, they should replace older holiday lights. Toys and ornaments with cords should be plugged into outlets in areas inaccessible to horses. If left in front of a stall, horses can easily drag it into their stall and start a fire or chew on the cord and electrocute themselves.

The holiday season should be a time filled with fun and festivities. Sharing this with equine friends is a common occurrence in most barns and with a little knowledge, common sense and advanced planning everyone should be safe and sound.

To Psyllium or Not - Hay is the Answer!

Like many things for our horses, the basic, simple things in life are often the best. Check out this article by Monique Warren - Sand Colic - The Surprising (Simple) Cure & Prevention for a look into the effectiveness of hay vs psyllium husk in preventing sand colic.
According to studies at the University of Florida, hay is overwhelmingly the most effective way to move sand from the digestive tract and prevent accumulation.
Like salt, clean water and exercise, hay in amounts to provide adequate gut fill is essential for our horses' well being.  When grain or high calorie lower fiber hay is substituted for high fiber forage, especially when "meal fed",  horses become more susceptible to sand impaction and colic.  I recently spoke with a gentleman who has transitioned his high level dressage barn Warmbloods to grass hay, minimal grain and a quality supplement with elimination of long standing hoof problems and improvement in overall health.
It's not always possible to provide a "natural" environment for our equine companions and athletes.  They are stabled for our convenience and asked to work in ways a free roaming horse wouldn't. But they also benefit from advanced veterinary care and explosions in knowledge about horses' basic needs.  Slow feeders - whether hay nets, Monique's Hay Pillows, or one of the many other options now available - can play a part in creating a more natural environment, especially for horses unable to graze because of stabling, travel or metabolic issues.

Other things to consider - standing up for your show horse by refusing to clip their all important whiskers - called vibrissae - sensory organs which help them recognize and sort food and prevent face and eye injuries.
To trim or not to trim your horse’s whiskers? The jury’s out…
Gemma Stanford, the BHS Director of Welfare, told H&H: “The purpose of the horse’s whiskers both around the eyes and muzzle provide sensory feedback on the horse’s environment. The length of the whiskers determines the safe distance from unfamiliar objects or substances and enables them to determine unfamiliar characteristics of food or detect small inedible objects providing an environmental map.*
We can enjoy our horses while helping them be all the horse they can be.

Quality supplements: while hay testing is the ideal, consider AZ Copper Complete or other flax-based supplements from HorseTech
