Late spring summer and early fall. if you put one on them. Ive hardly ever used blankets and there fine.
Winter I should imagine.
it depends on the weather,season, and the kind of blanket
Usually you'd get your horse a new blanket in late fall or early winter. Or what ever the coldest season for your region is.
winter and fall but mostly winter
Winter
The answer is pretty simple... WINTER!Winter
Winter
Season doesn't matter. If it's cold, you need to put a blanket on your horse. It can get cold in the middle of summer sometimes; you have to pay attention to the weather.
They need blankets in the winter time, so they can keep warm.
every other season apart from summer unless it is particularly warm
It would need it when it is cold, wet, rainy, or all of the above. Usually winter, spring, and late fall.
If your horse shivers from the cold in the winter, you need a blanket. some horses get cold easy other don't. If you live where you don't get snow I would just let your horses grow there extra hair the natural way, but if you live where it snows you should put the blanket on.
