Go ahead and read up on what a death due to rabies is like. After that, you'll definitely never neglect to treat a wild animal bite seriously. It's the stuff nightmares are made of.
I had to convince a coworker to go to the ER to have a cat bite looked at, and she ended up spending a couple of days in the ICU with the doctor being clear that delaying treatment another few days would have been fatal.
This one covers several things but is basically motivated by spreading the bad news about the seriousness of cat bites, as made clear by the alt text.
The course after that is a few weeks of effectively rapid-onset severe dementia. Animals don't get violent and unpredictable because the virus is simply angry-making—they get that way because they stop recognizing once-familiar things and can't remember how they got where they are, and so are constantly fucking terrified, plus their throats are closing up so they can't eat or drink (assuming they could remember to, or how to) and are experiencing dehydration and starvation. That's your near future by the time there are signs of the disease. You're about to dehydrate to death over a period of low-tens of days while becoming increasingly confused and frightened by your situation and by your own loved ones.
It's absolutely horrifying.
Since Clostridium tetani is anaerobic and in fact can't survive in the presence of oxygen, a lot of the things people suspect could give it to them likely can't. Unless you cut yourself while digging it's pretty unlikely you've been exposed to tetani.
And not to downplay your fears too much, but untreated tetanus is ~7% fatal versus 99.9% with rabies.
Like botulism or bacterial gangrene, tetani can survive for short periods (as can humans sans oxygen) but is unlikely to be found in sufficient quantities to cause concern.
