At least CBS is having a little fun with their new summer reality competition.

The network sent out a press release saying that the premiere of Greatest American Dog got the highest prime-time audience among dogs since an episode of Lassie in 1974. They also say that the show won its time slot against Ugly Betty "in dog-patrolled households, canine viewers, upscale purebreds, Heinz 57 (mutt) adults, and the advertiser-coveted 1.79-7 year-olds."

The press release goes on to say that the show did better than the network thought, especially since the test audience of dogs in Las Vegas didn't show numbers this high. The number should go higher later today when "factoring in dogs who know how to use their paws to program their DVRs."

As mentioned before, National Geographic Channel's Explorer kicks off its new season on August 8. I saw a preview of the August 15 episode, "Science of Dogs," and it's quite interesting.

We all know that dogs are a result of selective breeding, but I had never given thought much about what that means exactly. These are animals we have selectively bred over centuries to suit our needs: for hunting, companionship, protection, and myriad other possibilities. This type of breeding can be good, but it also has consequences, with one in four dogs stricken with some kind of genetic problem or defect. Since dogs often have the same diseases as humans, doctors can study the dog's genetic makeup in order to better understand and cure the same diseases in humans.
