My dog is the best friend I could ask for but since I divorced my husband I am so busy working to afford rent by myself that it's hard to have time to be with him. what can I do (besides selling him)?

One of the hardest things I ever had to do was give up my dog when one of my very early realationships ended.... I walked  out of that relationship with no material possessions at all ... All I took was our dog cos he wasn't safe there and neither was I  ... Then I realized I had to work twelve hour days just to start over ... I found him an awesome home cos I couldn't take care of him then ... Sometimes when you love someone ( including a dog ) you love them enough to give up everything  for them ... Then let them go.... Don't sell him ... Give him to a good home :) cos I said so. ....I'm sorry you have to lose your best friend.

Can you get a roommate to help with the bills so you don't have to work so much? Or do you have a family member or a friend that can take the pup so you can at least visit?

Isn't there people who can dog sit? Like a doggy day care? Not sure how expensive that is though.
