Debbie,
as others have said, yes, are you good enough of a photographer to take good pet photos? Yes. Are you a good enough business person to be able to run a pet photography business, market yourself and meet the needs and wants of your clients? Well, now, that's an entirely different set of questions. To be successful in this business you have to have skills that go far beyond being a great photographer. You have to have the technical skills -- the ability to create great images both inside and outside -- but also the ability to run a business. To be able to manage your cost side. To be able to generate adequate revenue. To be able to nurture client relationships and generate return sales. Compared to those skills, photography is a walk in the park for most of us with basic, solid photographic talent.

The good news is: those skills can be learned. But you have to be willing to invest the same (or more) energy in gaining your business skills as you have in developing your photographic skills. You'll need to invest: time, energy and, yes, money. You'll have to understand what your market is and how to reach them. You'll have to understand what your product is and how to price it. In short, in order for you to make photography your business, you have to have build your business skills to the same level as your photography.

Good luck. It's a great journey so enjoy it.

Jim
