How is everyone managing during Britain’s 2018 heatwave? We’ve been doing horses and any outdoor jobs in the morning and evening; hiding from the heat during the day because it’s too hot for anyone, let alone babies.
In general, horses in the UK seem to find it difficult to adapt to the heat. Partly because it’s so infrequent and comes along suddenly, and partly because a lot of horses are colder blooded, native types with thick, dense fur.
So with the hot weather, comes a few routine changes. I for one have been riding later in the evening. In my pre-baby life, I’d have been up with the larks riding in the cool. Schooling sessions become shorter or non existent. I did a lesson yesterday morning which consisted of about fifteen minutes in trot, split over the lesson, and the rest in walk. It was a good opportunity to practice lateral work without stirrups and nit pick on my rider’s aids. Hacks become much more appealing, don’t they? Any woods provide some shade and there’s usually more of a cool breeze. I read last week that horses feel the heat more than we do so it’s important to consider them when deciding to ride.
Some people prefer to have their horses stabled during the day in summer, and turned out overnight when it’s cooler and there are less flies about. For me, it depends on the horse and their field. People underestimate the shade that trees provide. I found this out a couple of weeks ago at a wake. The back garden of the house we were at had several large trees on one side and a sunny patio on the other. Sitting on the grass under the trees I was lovely and cool while those sat at the patio table with a parasol up were still boiling hot. So if your horse’s field has trees to provide shade and they aren’t bothered by the flies I would personally prefer them to stay out where they can move around and benefit from any breeze (which also deters the flying pests) that’s about. It’s also worth considering your stables. Wooden ones can become ovens whilst stone barns stay lovely and cool.
Wash them off liberally. Yes they may not have worked up a sweat walking around the woods, but they’ll still be grateful for a shower. There is the age old argument about how to cool off horses properly. The way I see it, the majority of the time horse owners aren’t dealing with a horse on the verge of hyperthermia and heat exhaustion (this week excepted) so hosing them and allowing the cooling process of evaporation to cool them down is sufficient. This week though, you may want to opt for continuous hosing and sweat scraping to bring down their core body temperature quicker.
Then of course is ensuring they’re hydrated. Horses will drink more in hot weather, much like us humans, so making sure they have plenty of clean water available is paramount. Ideally the water wants to be cool so that it is more appealing to the horse and refreshing. Standing water buckets need to be in the shade, but be aware of flies congregating around them. Self filling troughs are very often cooler despite being in the full sun because they’re continuously topped up with cold water from the underground pipes as the horses drink.
When a horse starts to get dehydrated they also stop wanting a drink, which obviously compounds the problem. What’s the evolutionary benefit to this, I wonder? It’s far better to never let them get thirsty in the first place. Adding salt to their diets, in feeds or with a lick, encourages them to drink. It may also be worth having a feed such as Allen and Page’s Fast Fibre which has very little calorific value but needs soaking for ten minutes before feeding. Adding that to their bucket feed, or even substituting that for part of their hay ration will help keep them hydrated. Some horses like their bucket feed to be sloshy so that’s a good way of giving them more water. You can add electrolytes to their feed too which aids hydration.
With this intense heat we’re having, there’s also the risk of sunburn. For both humans and equines! I heard a few weeks ago about a horse who had been clipped. I think he was a predominantly white coloured. But over the next couple of days his back got sunburnt due to the coat no longer protecting his pink skin. That’s a good reason to use a quality UV-proof fly rug, only half clip or indeed not clip at all! The UV-proof fly masks with nose nets are great at protecting white noses, and using factor 50 suncream helps prevent sunburn – don’t forget to use it on yourself too! I’d also be wary of white legs, particularly on fine coated horses as these could also suffer from sunburn.
Finally, check they aren’t overheating in any rugs. A lot of fly rugs are very breathable and thin, but sweet itch rugs tend to be of a thicker material. It might be worth using a lightweight fly rug on a sweet itch horse during the day, and sacrificing it if they start a scratching session and them staying cooler rather than them getting too hot in a sweet itch rug.
It is also worth reading up on the signs of equine heatstroke and be prepared to call the vet if you think your horse is suffering from it. Here are the symptoms:
-High respiratory and heart rate
-Dry mucous membranes in the mouth – they should be pink and have a slimy feel to them. To check the mucous membranes, press your finger on the gums and they should turn white with pressure. Once you have released your finger they should return to a normal pink colour.
