I have been waiting for school to be over before I get some dogs, and I just realized that I might have to pull some pretty crazy hours in residency too. Talk about ruining my life plan, LOL. Are there any single residents out there that have dogs and how do you handle it? I heard greyhounds sleep like 18 hours a day, so are there any other breeds that can be left alone for long periods of time? Happy New Year! Cheers!
