Hard to believe I hadn’t heard of this vertical ad network until I read this article in MediaPost today. The DogTime Media site claims they have 180 high quality pet site partners; the MediaPost article mentions another 130 bloggers. The network claims to reach more than 10 million visitors a month and enables content sharing across the sites. The advertisers mentioned in the article about a new chat application include the usual suspects: pet food, big box and cleaning machine manufacturers.
