Would you be a dog walker

I found a website that’s for dog walkers and it’s called wag. I passed the test to be a dog walker and the shipment to my house for the shirt and stuff is about $31. I want to be a dog walker so bad because it reminds me of when I used to walk my dog when I was younger and now I get paid for it. But my worry is that what if I get to their house and they don’t have a dog or they try to do something to me. I don’t know how much I’ll get paid for walking the dog but I hope it’s good money
