I like Hannikats idea, from a marketing point of view, it sounds professional and modern, although I don't know a lot about your business, will you have a studio available to you for dog/cat pics, if not then I suppose it may convey the wrong idea.
From an SEO point of view, definitely choose a URL with your high ranking keywords in, I am a web designer and so much of our companies time is spend redo-ing clients websites because they do poorly in the search engine rankings. Most are now high up on page 1 of google for their keywords.
