Look into it... Try it out. If it makes you happy go for it. I bet groomers in business for themselves make pretty good money. I don't know that for a fact, but it seems like they would. What's better than making money doing something you love.
When I was a teenager (like 16) I worked in a dog groomer place for a couple days and couldn't handle it.. lol. When they told me I had to squeeze the butt clean, that was it for me.. hehe. But like I said, I was young, so of coarse that weirded me out. lol
