Michigan: Kid climbed over my fence. Was next to my deck steps when I let my dog out. The kid was nipped by my dog in the thigh.

I have a related question that I would love to have answered:

I worked as a pizza delivery guy for a huge chain and several months ago, I delivered to a house and was bitten by their dog. The family left their dog outside, and it bit me in the back of my left leg. The dog broke my skin with its canine tooth, even through my long pants. I wanted to get my leg cleaned up and looked at to make sure it wasn't going to get infected or anything, and I assumed the gigantic pizza company I work for would pay for it. Work said they would pay for me to get my leg looked at, but the first thing they would make me do (before looking at my leg) was give me a drug test. If I failed the drug test, they would not look at my leg or compensate me for the visit, and I would be fired. Since I smoke weed regularly, I couldn't go to the doctor. I ended up having the owner of the dog email me the dog's vaccination record to make sure that I wouldn't get rabies, and cleaned up the bite myself with a lot of rubbing alcohol. The dog got me really good because the bite still feels bruised several months later. I am aware that I have probably missed any chance for legal recourse due to my inaction, but here is my question:

Is it actually legal for my ex-employer to refuse medical treatment until I pass a drug test for an injury suffered on the job caused by an animal? I understand drug testing if I had gotten in a car accident and they were going to pay out an insurance claim, or if I had a self-inflicted injury, but is it legal for them to require a drug test before medical care for ANY injury suffered on the job? Like, if I delivered to a house in the middle of nowhere and a pack of wild coyotes had mauled me and left me bleeding from several dozen wounds, could they demand that I pass a drug test to get them to pay for my treatment? If I tested positive for marijuana, could they legally say "we're not going to help you pay your medical bills for the coyote bites you suffered on the job (by literally going to the exact place we told you to go) because at some point in the last 30 days you consumed marijuana, so you might have been high when you got attacked... and there is totally a correlation between you being high and getting attacked by a fucking animal"?

I need to know if this is actually legal or not.
