Not me, but the practice that takes care of my horse hired a new doctor last Summer who was straight out of school and she's done really well with them. But as mentioned above, I think it really depends on the region and what type of caseload the practice sees. The practice I use is a smaller practice and they also see small ruminants. If you could find a smaller practice or one where the caseload is a lot of hobbyists and "pet" horses it could be doable, but it seems like at least around me the bigger practices, or ones with a heavy sport horse caseload usually want an internship.
