Happily coinciding with the Westminster Dog Show (the Super Bowl of the dog world), FetchDog, an online portal for dog owners to shop and socialize, just raised $4 million to expand the scope of its web presence and services. Right now, users can use the site to find everything from chew toys and leashes to car seats and eco-friendly pet gear. Perhaps its most notable claim to fame, however, is that one of its founders and active supporters is actress Glenn Close.

In addition to running its online and paper supply catalogs, FetchDog gives owners a chance to discuss issues important to them and their dogs. It also works closely with several charitable initiatives and adoption groups. Users can elect to “Shop for a good cause” — if they buy certain products a percentage of the sale will go to various animal rights and rescue groups, including Puppies Behind Bars, Picasso Veterinary Fund and the ASPCA. These products come in collections handpicked by various dog-loving celebrities (in addition to Close) like Martha Stewart, Ted Danson and Rachael Ray. The site also runs Q&A columns with stars about their involvement with the company and the canines they love.

The Portland, Maine-based company says its mission is to become the default online source for dog products. Of course, the concept comes with a healthy share of targeted advertising opportunities that have yet to be tapped. Based on the relatively wild success (considering the downturn) of other dog enthusiast sites like Dogster, it should have no problem drawing a healthy consumer base. The other major online dog product catalog, the obvious Dog.com, has a good range of offerings, but lacks FetchDog’s philanthropic and social bent, and of course the glitz of its Hollywood backers.

The recent investment round was led by Borealis Capital Partners and Harbor Light Capital Partners. FetchDog previously raised money from Black Point Group, David E. Shaw, William T. End, Benjamin Shaw, and of course, Close.
