ELI5: How can dogs pick up objects from the ground so much without getting sick?

How is it possible that dogs are able to put just about everything in their mouths and eat food from the ground without getting sick?

Dogs just have a more powerful/tolerant immune system regarding that kind of stuff since...well, they are still used to eat things off the ground as opposed to most humans.

If you'd were raised from birth eating stuff off the ground everywhere, you'd probably have a much higher tolerance to it too.

(Note: Please do not start eating things off the ground to train your body)
