The app i mentioned in my previous post is actually made on the Tumblr blog called "The Daily Wag". If you don't have an android device but still want to check some of the cutest puppies - follow this blog:
http://thedailywag.tumblr.com/. New cuteness is added all the time, small, fluffy cute little and not so little guys;) Check it out, no need to have Tumblr account to look but if you want to reblog or like/share - create one for free. "The Daily Wag" is having a fancy addition - the app Cute Puppy Pictures which is free on Google Play Store;) Have fun with all those little cute pups.
