I actually just finished grad school. My dad works nights so he was able to let Lucy out in the afternoon because sometimes I would be gone for 12 hours depending on my class schedule. I am looking into getting an xpen for my next puppy since I will have to start work in about a month
If you have a friend or family member, or even a trusted neighbor to let your pup out it helps a lot! I think I am going to pay my little sister to come over after school and let the girls out.
