I approached my landlord again about raising a puppy full time. We'll see what he says. It would be so nice to have a dog around full time again. If he does say no at least I'll still be able to be a sitter. It's not ideal, but at least I'll still have a pup when I need one.
I sent the email about 4 days ago and I haven't heard back as of yet. I hope that means he is thinking it over instead of just saying no immediately. It's hard to be patient sometimes.
