I have three horses, all Standardbreds in which we used to race. Now they're just recreational horses. Two of them are really clean, the 15 year old mare (mother of the two others) and our 8 year old gelding. They only take about 5 minutes to clean their stalls. But our youngest 5 year old mare is a real pig. My dad has even mentioned that a pig would actually be cleaner then her. She takes around 10-15 minutes to clean.
Is there any tips on maybe training her to be cleaner in the stall? We don't know why she is so messy. It seams to me that she spends her whole night messing up the stall!
