Mail delivery vs dog walker skills

[ella]

What skills do I need for both? Which job is better in terms of pay?

Mail delivery-
You'll need to know how to drive
In some places, you will need to pass a postal exam, which is very easy

Dog walker-
If you can show you have pet dogs in the past, that should be enough
