With all the rain there is no risk of Brena getting thirsty along the trail. Like some other memorable horses she does love to drink from puddles. I don't mind. There are no problems with polluted water along the trail. And it's better to drink along the way than to refuse to drink. I believe that she really likes this water too. Up here it's a little chalky, but then so is the artesian water served at the barn. It's all good for the bones.
Fortunately I've never had a trail horse that wouldn't drink. Back when I had a string of trail horses they would all drink willingly from streams and troughs. Some drank more quickly than others so the rule was to wait until the last one had finished. I mean really finished. That required a little patience, as there were individuals that would raise their heads, pause and think, then get back to drinking. It's easy for an impatient guide to get a horse or two dehydrated. Sometimes the riders on the quicker drinking horses needed to be asked to wait.
Usually lack of water is the problem up here on the chalk. In summer the hills are bone dry. There are no streams up here, and hardly a pond accessible. A few troughs remain in fields from the days when there was more livestock, and a handful of these are still plumbed to clean water. Occasionally one comes across a field of sheep with their own supply of fresh water. But right now dry is a word little used. Summer is an ephemeral concept. After the wettest January in a century most land is sodden and the remainder flooded. We are longing for the arrival of spring.
