For sure,wait a year here before bringing the horse to school. You might have some free time now because you haven’t really gotten involved with new friends and the usual college extra curricular activities. You might want to join some things or compete for the school. I traveled with the Speech team and helped with Debate topic research. Made friends I had for years.
I kept and paid for the horse working several jobs that progressed into a 25 hour a week permanent position with benefits but lived at home with recently widowed Mom. Win Win. But because I had the flexibility to let horse sit when I didn’t have time without sacrificing everything else in my life. Didn’t get through in 4 years either, might mention that. Much more leisurely pace, no rush to a job to pay off student loans either.
