Take him with you, ask to work a couple hours a day....whatever it takes, right? plus you will get something new to put on your resume, and a reference!
My mom was a single parent with me and somehow she muddled thru, my parents divorced when I was 2 years old too.
I understand about the money probs, I'm in the same boat...I was badly freaked out about Juneau's howling and called my vet and the prices for the spray collar are *ouch* and drugs are expensive, and he'd just pull an anti bark muzzle off.

According to the landlords, he's pretty much stopped howling, and they don't seem to really care if he does, cept he does it when i leave at 7 15 am LOL.
