Has anyone had success with promoting on Instagram?

I currently share business cards, and post on my personal Facebook page and local community Facebook pages, and lately I've been considering starting an instagram profile for my business. Partially for fun, just to share with friends and family what I'm up to, but ultimately for promotional purposes. Of course everyone loves dog photos, but I don't want to pour effort into keeping up an instagram account if it's not going to lead to as many clients as maybe another promotional method would.

Any thoughts appreciated. Thanks!
