He'll get long in the toe and may flare some, but if he's just loafing around the pasture he should be fine 'till you get back. You can get him back on his regular schedule after that.
That's the worry, him losing one after he's gotten longer, and breaking it again:\
I'm really going to try to get back to some kind of at least lunging schedule next week. And hopefully get to ride a little. I guess if I hear him really starting to click a lot, I'd get him shod sooner.
