Dog grooming is not blogged about much, but perhaps you could try to arrange an event for dog owners to teach them about dog grooming, or perhaps you can try to speak at an event where dog owners gather? By establishing yourself as an expert on dog grooming in your area, you should start to rank well in local searches.
I'm not an expert on local search, but it probably won't hurt to be on Foursquare and so on as well (http://webmarketingtoday.com/articles/for-local-seo-use-check-ins-at-foursquare-and-facebook/)
