I’m from Germany and I don’t know people who give their horses 4 weeks off in summer and also not in winter. I give my horse like one week off here and there if I have to do other stuff. And that’s how most of the people do here. We usually don’t do it in winter because they can’t go out in the fields for too long. Only four hours.
From spring to autumn our horses are out in the field from morning till evening. :)
@emiliadevoe where I live in Europe we typically give them a 4 week vacation during the winter because show season is in the summer :)
Generally I think it’s a bit difficult to compare Europe to the US or Canada because Europe is a continet and there are huge differences how the countries care for their horses. Here in the north it’s generally really important for us that the horses go out many hours a day while in Central Europe (what I’ve seen) it isn’t as common.
