Bugs tunnels from underneath and finds himself at the local dog track After checking out all the entries, he wanders over to the fence to get a close look at the race.
It begins and, lo-and-behold, there's a cute little rabbit! Bugs is immediately smitten. Unfortunately, that's the mechanical one the dogs chase each race. Bugs doesn't know it's a fake, he thinks "she" is cute and he's going to save her before all those dogs catch up to her.
Bugs does his best by trying to eliminate the field, one by one. However, the gray dog is more than a challenge for Bugs....and, for some reason, Bugs has a hard time catching up "to that dame."
The cartoon is funny and something a bit different. I can't recall seeing any cartoons involving dog (greyhound, to be exact) races.
