Speaking of, now THAT is a way you can make money. Do your dog in something super fancy...red white and blue for American holidays for example. Christmas colors are also popular.
Now you take your dog out and just talk to people..hang out at dog parks or places where pets go. Offer your creative services to other people, I used to. Be your own boss and become a part time groomer. If you do your dog well, you will advertise your services with ease.
I groom my own standard (he is just black, nothing creative there) and I get propositioned to groom other peoples dogs all the time. I used to in the past for the cash, now I just don't have time anymore. While I've never worked as a professional groomer, you'll find plenty of people that are willing to give you a try if they can pay you less than they would at a salon. Most people simply want their dogs shaved during the summer....and almost anyone can do that.
