Dogtime Media, which sells ads to a network of pet-related sites, has taken in $1 million from angel investors, notes Alarm:Clock, which found a Craigslist help wanted posting saying as such.  The company, which likens its model to Glam Media, uses Adify, an ad platform designed for vertical content networks.  The company is also gearing up to launch its flagship site DogTime.com, a central hub of dog-related information.  No word on who the angel investors are.
