I have always said Sienna is 'square' LOL and it's about true. I don't give her grain, except for the handful the BO used to give her when she came in because the other horses got it. I've cut out treats now that we've worked on her staying put when I come up to her in the pasture, although I still have to occasionally have to 'join' with her again, LOL when she tests me. And in a pasture that's a lot harder on ME than her and I swear I think she knows it. I'm out there huffing and puffing cutting off her drive line. But she just does that for some perverse sense of fun sometimes. But she's about as wide as she is long, LOL. When I got her she honestly didn't know how to eat grass, had been kept and mostly ignored in a paddock with a tree, hay and water. We put water on the ground right next to her hay in the arena where she stayed at first and she would dunk in. Somehow she remembered it was supposed to be moist, but grass? (It was August) no interest. I spent a lot of time just being with her at first, and I would 'mosey' her around the farm, let her check out new things. One day I was there just hanging out with her in the arena because it was raining outside, a very light gentle rain for around here. When it quit, I decided to mosey her, and she sniffed some wet grass, took a tentative bite, and hasn't quit eating since, LOL. Seriously she is so round I can't mount her from the ground, because of my disability which sometimes keeps me housebound and sometimes lets me be quite active. So I'm overweight, and not really as flexible as I could be maybe if I worked on it, and putting my foot in the stirrup and trying to bounce on my right foot to get enough momentum to get me on her always ends up with a slipped saddle. (I recently lost 20 lbs and working on more since spring has finally come KINDA to VT). Oh well I digress, LOL. Anyway she's a chow hound but very pushy about treats, well food in general, so I quit giving her treats for anything, just a good scratch on her itchy places. But Sienna uses her run in more for sun than anything else. Rain and snow don't seem to bother her. She's a hearty little thing.
