I understand there isn't a magic pill you can take to build six pack abs. 

My name, for example, is so common that I've gotten somebody else's prescriptions from the pharmacy - because we had the same name.

Bottom line is, before you accepted the tenant, you're entitled to, and should not accept them without something in writing from a licensed Doctor or professional that designates the dog or "animal" as a prescriptive necessity.  

Potential tenant with felony prescription medication conviction, not violent, wasn't incarcerated, sounds like previous landlord said he pays on time.

But I will still fight for myself a little longer to see if I can possibly get some skin in the game to prevent me from having to swallow that bitter pill or at least maybe a little  lesser tasting pill.

If it had anything involving heroin or prescription opiates I would also say HELL NO.  

I simply told my tenant that if she can provide a legal prescription from a licensed physician, she can have the dog but must provide proof of all vaccinations as they become due from a licensed veterinarian.

I do need to put a new roof on it soon but with such low rent, it's a hard pill to swallow.I may move back into the house in a year or two.

Two wordsDue DiligenceThat's going to be a hard pill to swallow. 

Well right now at 37 I do not have health insurance.Luckily I have been very healthy so far with little to no issues.The issue I have is policies.The insurance companies do not cover much of the payment yet charge a high monthly fee for their policy.If you go into a doctor's office with insurance they will charge the maximum from the insurance company.So example with insurance a bill comes to 150.At 50% my co-pay would be 75 plus I am paying monthly to the insurance company for the policy.If I say I am not insured and pay cash they charge me 100.I save on costs not having to pay monthly on the policy just when I need to go AND I don't have some stupid policy telling me which doctor I have to go to.I also don't have the primary care doctor pumping me with pills which have side affects because the insurance company doesn't want to pay to go see a specialist to fix the problem.Also the specialist that you have to go to with the policy can be far away and the a long time before you get to see them so you suffer longer.Now you can get catastrophic care if you need to go to the hospital.You save on regular doctors visits but if you have something serious you get the insurance to cover the large bill.
