I just finished undergrad in May, and I start grad school in August, so I am pretty familiar with what you are asking about. I think it's fine to have pets while in college, as most people have pretty flexible class schedules and can be home to take care of and play with the pet most of the day. However, a pet freshman year probably isn't the best idea for a couple of reasons as others have already mentioned - freshman year of a 4-year college is pretty overwhelming anyway and almost every dorm has a no pet policy. However, having your yorkie later on (when you move off campus to an apartment maybe) would be fine, and he will be a good little companion
