If you like to spam your friends with photos of your canine companion on your own Facebook or Twitter page, Woof for iPhone may be the perfect app for you. You can build your dog their own profile, follow other dogs, and even track walks and view parks and other Woof users' walk routes.
More than anything, Woof is pretty much a social community for dog lovers. Aside from sharing photos, the most useful features of Woof are its abilities to let you view and map out walks and dog park locations. You can even label them as no leash, fenced in, and add other attributes. It makes for a great way to find dog friendly environments near you, especially when traveling with your dog.
I've found Woof to be completely entertaining and useful in the little amount of time I've spent with it. One major issue I have though is that you can't have more than one dog under one account. You'd need to log out and log back in with another account. For those of us that have more than one dog, that could quickly become annoying.
If you're a dog owner, there's no reason not to check out Woof. After you do, let us know what you think!
