Horse Stall Bedding and Horse Health

Success horse health begins in your barn… Start with your horse bedding. Everything brought into your horse’s life and existence will produce an effect. This includes nutrition, exercise and the environment you provide.

One of the profound and enduring questions equestrian enthusiasts ponder: “Is my horse better off inside or outside?”

Horse stall bedding

There are many sides to this question with one not necessarily dominating the others but if your horses are stabled take a close look at the bedding product you select. Stabled horses spend between 800 and 8400 hours per year in their stall.

Skin is the largest organ in the body of a horse and their skin as well as their respiratory system is exposed to the bedding in the stall.

Your horse’s stall is his home and safe place; as stewards we accept the responsibility to ensure it remains so. We are presented with more options than ever before to choose horse bedding produced from wood, paper, straw, assorted plant fibers and peat moss. But be aware that like feed, vet care and horse bedding, too, price does not always equal value. Your choice of stall bedding will have an impact on the health and performance of your horse. We hope this article, from the perspective of manufacturer as well as horse farm owner, will help you choose a safe and healthy product.

While price will be a consideration in your choice of product, consider that a low priced, poorly packaged product made with questionable or unknown materials can cost more later in vet and farrier bills, boarding disputes as well as performance issues. While the typical bedding hazards are well known to experienced horse people, newcomers to equestrian interests should make themselves familiar with the most common and potential threats lurking in their horse bedding. The common hazards include Black Walnut (toxic), Red Maple (toxic), Black Cherry (toxic), Cedar (allergies), Cypress (allergies), dust, moisture content, mold, excessive oils… but we’re only speaking of source material here and no reputable bedding manufacturer would knowingly include these potentially fatal components into their blend.

Other dangers can include careless manufacturing and storage practices as well. While volume statements are mandated and enforced by law, a broad and general statement regarding the contents of the bag can be misleading. While not typical, it is also not uncommon to find low priced demolition materials blended to pack out a bag and reduce costs at the point of manufacture. This can include ground up pallets, waste from construction sites and therefore, not limited to strictly wood. While it is common practice to use magnets and screens to safeguard against including foreign material in the bag it begs the question: are the safeguards failsafe? (no); do magnets and screens need to be cleaned frequently? (yes); are the magnets and screens cleaned frequently? (maybe; maybe not). Pallet grindings run the risk of being contaminated by the materials they carried.

These concerns range from poisons, chemicals, molded foods, etc. The point to consider is that a low priced bedding may be using low priced source material or, in some cases, free material that is decidedly waste and was destined for a landfill. Knowledge of the contents of your bedding bag is critical to your horse’s health and well-being. If there is any doubt in your mind, don’t be shy about calling the manufacturer and questioning them about the raw material source. Most will be happy to have an opportunity to discuss their manufacturing methods, pristine raw material and commitment to excellence.

The other critical element in producing a high quality healthy product suitable for use in a horse stall is packaging. That is to say, poor packaging and storage practices can also affect the performance and usability of an otherwise quality bedding product. Depending upon where you purchase your product, it could be stored outdoors for weeks at a time. If the product is not packed and wrapped correctly and then subsequently exposed to the elements of rain, snow, sleet, etc. you could be purchasing wet and molded product. While the obvious disadvantage is a poorly performing bedding product, the more insidious danger is the effect of mold spores to the equine respiratory system. Prolonged exposure will require veterinary care and most definitely affect your horse’s performance. Storage is not only the responsibility of the manufacturer but the retailer as well.

The manufacturer could deliver a perfectly good product to the retailer, but if the pallet of bedding is opened to get a couple of bags off, not resealed properly and then left outside the exposure could then damage the remaining product and render it unusable.

Fortunately, for those of us that closely examine all of the products we bring to our horse’s lives, we have some good options for quality bedding. While properly processed pine remains the best choice for overall horse care, (absorption, ammonia and allergen control) reasoned consideration can also be given to peat moss, straw (especially for foaling stalls) as well as other softwoods such as aspen and spruce when pine is not available. Hardwoods should be avoided as lignin exposure can be toxic and hardwood will not absorb as well as softwood. Any product that contains pallet or demolition material (most of the bulk materials as well as some bagged product on the market today) should be heavily scrutinized.

Use this checklist when assessing your current or a new source: 1. What is the full ingredient list of the product in the bag? 2. Do you use any fillers like ground pallets, construction or other post-consumer wood waste? 3. Is the wood high heat treated to a moisture content below 12%? (important to avoid mold in the bag) 4. What temperature is the treatment? ( this is important in assessing removal of potential allergens) 5. Where is the product produced? (city and state – be suspicious if this cant be provided) 6. Are the shavings screened to remove dust? 7. Can I receive a small sample of the material that represents what will be in the bag? 8. How long have you been manufacturing horse bedding? 9. Do you have any third party testing results available?

Key Article Takeaways
  • Stabled horses live in their bedding 800–8,400 hours per year—it touches skin and lungs constantly.
  • Skin is the largest organ; respiratory tissue is the most sensitive—both react to the wrong bedding.
  • Wood, paper, straw, plant fibers, and peat moss each carry their own dust and absorbency profile.
  • Price doesn't equal value—dust-extracted shavings often cost more but pay for themselves in vet bills.
  • Match bedding to horse: respiratory issues need ultra-low-dust; foals and laminitic horses need different criteria.
Questions readers commonly ask:
Why does bedding choice matter so much?

Per InfoHorse: stabled horses spend between 800 and 8,400 hours a year in their stalls, in direct contact with bedding through skin and respiratory system. The wrong bedding triggers skin irritation, hoof problems, allergies, and chronic respiratory conditions like RAO (heaves)—conditions that often resolve when bedding is upgraded.

What's the lowest-dust bedding option?

Per InfoHorse: pelleted wood bedding, hemp, dust-extracted shavings, and high-grade paper bedding all run very low on respirable dust. These are the right choice for horses with any history of cough, nasal discharge, or RAO/heaves.

Is straw a bad choice for horse bedding?

Per InfoHorse: not bad—different. Straw provides excellent insulation, encourages natural foraging behavior, and composts well. The downside is mold spores in lower-grade batches, which is why respiratory-sensitive horses do better on dust-extracted shavings or pellets.

How often should I strip a stall completely?

Per InfoHorse: top-pick daily, full strip weekly to monthly depending on bedding type and barn ventilation. Pelleted beddings usually require less full-strip frequency than shavings or straw because they hold moisture differently.

What's the link between bedding and hoof health?

Per InfoHorse: ammonia from urine breakdown attacks the white line and frog. Whatever bedding absorbs urine fastest and stays driest at hoof level protects hooves best. Wet, deep, mixed bedding is a thrush incubator.
