Ok so I live in Minnesota, my horse is outside 24- 7, he is a 16yr old Thoroughbred. I have never used a blanket in past years because I always new he had a shelter he could get into if he wanted and he always had hay at all times if he wanted . But we had to move and now he is at a new barn and in the pasture with 3 other younger horses( 5-9yrs) the shelter is only large enough for 2 horses and I know he won't be one. The pastures are surrounded by lots of trees that do block the wind and the pasture also has a very low spot that is great for wind block. I do ride 2-5 times a week. If I put a blanket on him doesn't it have to come off daily? What do you guys think? I am really stressing out about this! I know once I put him in one he needs to stay in one, but things I read on the Internet also tell me that horses don't need Blankets that with proper hay source and there own hair will be enough. But what if it snows in the middle of the night all night long( it does happen) ?Also I am not sure how if he is getting enough hay because of the 3 younger ones but I will be keeping a close eye on his weight by using the wieght tape. I am so worried about doing the wrong thing please help!Sorry so long.
