I too am starting med school in the fall and I too am a dog lover. I am glad to see so many good stories coming out of this inquiry. However, one of the sacrifices I had to make in order to go to med school was that I had to find a new home for my two bassett hounds. Their are several reasons why. First, I could not find a place that would take pets for a reasonable amount of rent. Second, dogs can be expensive. It doesn't seem that way but when little vet surprises pop up you will find that Vets must be making some kind of money. For example, I adopted one bassett a couple of years ago. Two months after I got her her mouth started to bleed and I took her into have it looked at. Long story short, two months after that, I was out 2500 to squamous cell carcinoma, a dead dog and a broken heart. More recently, my three year old bassett has a propensity to eating things. Socks, rocks, glass, brick, anything he will eat it. So every time, I have to take him in because of an upset stomach (luckily he either throws up or passes the crazy stuff he has eaten), it costs about $160. Also, heart wormer is 25/month, food is 40/month (i fed them nutro), grooming $20/month (even if you do it your self), frontline flea protection $40/month, all of the neat toys you want to buy them, priceless j/k but it is expensive. Vaccinations, etc. it all adds up and 100/ month to a med student is pretty far out there. My last point is that I have raised several different breeds from pup to adult and there aren't many breeds that will be fully trained and ready for you to go to med school by this fall if you get them now. A puppy is almost like having a kid ( i have one of those too). I would recomend a lab if you want a quick trainer. So I hope it works for you. You will know what to do.
