American dogs live a life of luxury: Owners spend nearly $4 billion a year spoiling their pets. Now, cable network DogTV airs programming to stimulate and soothe "stay-at-home dogs." What does that look like? We didn't know either. Test your knowledge—are the following shows for people or pups?
1. This extreme dog gets his exercise by catching a wave.
2. A run through suburbia creates owner-dog bonding time.
3. These urban pups travel in well-groomed packs.
4. Both baby and dog buckle up for safety en route to the store.
Answer Key: 1. Dog: DogTV's "stimulation" rubric shows dogs in action. 2. Human: NatGeo's Dog Whisperer helps owners discipline their pets. 3. Human: CBS's Dogs in the City follows "dog guru" Justin Silver resolve issues between pet and owner. 4. Dog: DogTV's "exposure" rubric shows day-to-day activity.[[i]Image: Flickr user [url=http://www.flickr.com/photos/kratz/452589745/]John Kratz[/url][/i]]
