Long time horsey person here, but haven't owned my own since the '90s.
These days virtually every horse near me is fully rugged up at the moment, in 30+ degrees. Many including head/neck.
Back in my day the only horses rugged in high summer were those with sweet itch/fly allergies. Has this advice changed? Is this some sort of modern trend that's passed me by? Do you all rug your horses throughout the summer?
Just curious really!
