19. Walkies

If you have a dog, you obviously already take it for walks (and if you don’t, you should!!), so why not get paid for it?

Set-up a dog walking business and, while you’re walking your own dog, take your customer’s pups along with you as well!

Heck, if you have space in your house, you can even start boarding dogs during the day or overnight – it’s a great excuse to give your pet more social interaction and you can make a little cash from it!
