All except Rads are either DO friendly or just out right hyper uncompetitive. I think Rads is also apparently getting more DO friendly/ less competitive, but that may be since the field is in danger of invalidation thanks to it being easy to sending X-rays to India or having computers do it all.
...and you know all this how? by talking with every residency director at your program? wait, you're not in medical school yet.
yes, i was in your same shoes, wondering which specialties were attainable for DO before I got into MD. now that i've seen more, though, there's only so much you can predict in the future. everything above is just speculation.
step 1: focus on getting into the best medical school you want to go into, whether it be MD or DO
step 2: study hard during basic science MS1-MS2 years
step 3: get shadowing experience in the residencies you're interested in during M1-M2 years; best time you'll have to get to know the attendings before everyone does during clinicals.
step 3: kill boards (g'luck). take USMLE, even if you're DO.
step 4: evaluate scores, talk with deans, see which fields you realistically have a chance of matching in - or which ones you have time to still do stuff for.
this whole process is going to be years from now. friendliness is also program dependent, some have not had a history of taking DOs regardless of specialty.
