How much money does an dog daycare owner make?

Who knows? There's really no way of estimating bvecause it depends on how many jobs and how many dogs they get.

Well, I know since I own one. You'll make very little the first few years,and you'll work a lot too. And I mean a lot. If you are able to make it past the first few years, and establish a good customer base and most importantly wisely manage your finances you should be able to pull in 100k-200k per year.
