Yes I bet it would help.
You might consider putting raw acv in the water. I know a number of horse people use it with their horses when they in strange surroundings. Another option would be to bring your own water. I know that is not doable for a lot of people, but thought I would mention it anyway.The majority of my goats will hardly eat and drink while they are at shows.. Not only is this really bad for their health, it makes them look terrible too. I am wondering if electrolytes in the water and probios powder in grain would help?
