Greatest American Dog

Greatest American Dog was an American reality television show on CBS. It debuted on July 10, 2008 and was hosted by Jarod Miller with judges Victoria Stilwell, Allan Reznik, and Wendy Diamond. The winner was given the title of "Greatest American Dog" and a prize of $250,000.
Episode format.
Each episode had a theme, such as "teamwork" or "loyalty," that was tested through two different challenges.
The winner of the first challenge, the "Dog Bone Challenge," receives deluxe accommodations within the Canine Academy (similar to the "Head of Household" suite on CBS' "Big Brother"). In addition, for the first four weeks, the winner of the challenge got to send one of the other teams to the "Dog House," a much smaller building with few amenities. For the remaining weeks, the winner received a "leg up," some form of assistance that would help the contestant in the second challenge.
In that second challenge, the "Best in Show Challenge," the teams are evaluated by the judges. The judges then choose one or more winners (except for Week 1), and place three teams in the "bottom three." Of those three, the judges then choose the team they feel had the worst performance; that team is then "expelled" from Canine Academy.
Episode progress.

2 - In episode 10, JD & Galaxy were eliminated after a preliminary interview, and did not take part in the final obstacle course/interview.
Episode guide.
Here's To Man and Woman's Best Friend!
Original Air Date: July 10, 2008
The twelve competing dogs and their owners arrive at Canine Academy and meet each other for the first time. The theme for this episode was 'The Basics'.
Dog Bone Challenge: "Doggy Musical Chairs"
Best in Show Challenge: "The Talent Show"
The bottom three were Brandy & Beacon, Beth Joy & Bella Starlet, and Michael & Ezzie. Beth Joy was told her performance was disappointing when she lost control over Bella Starlet.

Michael was told that his own performance overshadowed and overwhelmed Ezzie, who was having difficulty focusing.
He's a Farter, Not a Fighter.
Original Air Date: July 17, 2008
Things grow a little tense at Canine Academy when Elvis has a small fight with Tillman and bites his eye. Elvis' owner, David, seems very passive about his dog's actions. Star suffers an injury to her neck and ear, and she has to be brought into an emergency vet to be stitched up. The cause of the injury seems to be unknown, though the vet suggests it may have been a feral cat. Star recovers with a bit of rest and relaxation. The theme for this week's competitions was 'Obedience'.
Dog Bone Challenge: "Doggy Boot Camp"
Best in Show Challenge: ""Pet"-iquette"
The bottom three were Elan & Kenji, Beth Joy & Bella Starlet, and David & Elvis. David was told that his particular use of hand signals was confusing and distracting. Elan was told that her communication with Kenji was confusing and stressful to Kenji. She was also told that she was bordering on being harsh with her dog. Beth Joy had put Bella Starlet in a dress that covered most of her body, which resulted in the judges being unable to evaluate her grooming.
The Fast and the Furriest.
Original Air Date: July 24, 2008
Elvis proves that he can 'play nice' with both Andrew and Tillman. The theme for this episode's competitions was 'Teamwork'.
Dog Bone Challenge: "Tangled Leash"
Best in Show Challenge: "The Fast and the Furriest"
The bottom three were David & Elvis, Ron & Tillman, and Laurie & Andrew. David had run Elvis over the teeter-totters on leash (all of the other dogs were off leash), and the judges agreed that Elvis may have performed better off-leash as well. The judges told Ron that they didn't see any teamwork between him and Tillman that week. Laurie was chastised for tearing a larger hole in the paper on the last hoop to give Andrew an easier time, as it was an unfair advantage.
Top Dog Model.
Original Air Date: July 30, 2008
The friendship between Laura and Travis continues to blossom, and Brandy seems jealous of it. Many of the contestants begin to stress over the Best in Show challenge. The theme this week is 'Personality'.
Dog Bone Challenge: "Take It or Leave It"
Best in Show Challenge: "Photo Shoot"
The bottom three were Ron & Tillman, Teresa & Leroy, and Brandy & Beacon. Victoria Stilwell felt that Teresa's use of "snarl bands" (an elastic band meant to keep the dog's lips raised) on Leroy to achieve the angry look was inhumane and potentially harmful. Brandy was told that she'd made a poor choice by having a white dog on a white background. Wendy Diamond told Ron that he "single-handedly [had] the worst photo of a bulldog [she had] ever seen". The judges agreed that the photo lacked any imagination.
Dancing with the Dogs.
Original Air Date: August 6, 2008
Brandy becomes stressed when Beacon seems to be ignoring her. Bill & Star continue to feel homesick, and Teresa picks up on it. This week's theme is 'Coordination'.
Dog Bone Challenge: "Mud Dog"
Best in Show Challenge: "Dancing with the Dogs"
The bottom three were Laura & Preston, Brandy & Beacon, and Travis & Presley. Travis was told that Presley could have been more enthusiastic about the routine. Brandy was told that putting socks on Beacon and poor training caused Beacon to shut down. Laura was told that Preston wasn't focused and that she had lost control of him.
Salvador Doggy.
Original Air Date: August 13, 2008
Laura and Travis continue to bond. Laura and Beth Joy argue during a deliberation for the Best in Show competition when Laura mentions to the judges that she'd thought Beth Joy had pushed Bella Starlet too far with certain paint-applying techniques. Travis helps to defend Beth Joy when the judges ask her about it. The theme for this episode's competitions was 'Intelligence'.
Dog Bone Challenge: "Doggy I.Q."
Best in Show Challenge: "Salvador Doggy"
The bottom three were Laura & Preston, JD & Galaxy, and Laurie & Andrew. The judges felt that the painting created by Laura & Preston looked very rushed and had little thought put into it. They felt that Laurie hadn't put enough effort into her work either. JD was chastised for seemingly trying to make mistakes in Galaxy's painting appear to be intentional.
The Big Dig.
Original Air Date: August 20, 2008
Beth Joy is upset when Bella Starlet begins to act aggressive. JD and Laurie have a discussion about the difference between their training methods, foreshadowing a heated argument between judges Victoria Stilwell and Wendy Diamond on the same topic after the Best in Show challenge. There was no specific theme in this episode.
Dog Bone Challenge: "The Big Dig"
Best in Show Challenge: "The Maze"
The bottom three were Bill & Star, Beth Joy & Bella Starlet, and Travis & Presley. Travis was told that his "hyperenergy" made it hard for Presley to respond to him and the challenge. Beth Joy was chastised for reducing her commands to "desperate bribes" as she got more anxious with Bella Starlet's performance. Bill was told that he had pushed Star far too close to her limit.
My Dog Can Fly!
Original Air Date: August 27, 2008
Things start to get serious with only the top five remaining. JD notices Galaxy is limping after one of the challenges. This week's theme was 'Courage'.
Dog Bone Challenge: "Elephant Charge"
Best in Show Challenge: "Stunt Dog"
The bottom three are Laurie & Andrew, Bill & Star, and Travis & Presley. Travis is told he was a little bit out of control while praising Presley on the very high apparatus the competition took place on. Both Bill and Laurie chose to take their dogs up the easier ramp and neither Star nor Andrew would jump down via the zipline when encouraged to do so. The judges chose to expel Bill & Star because they felt Star could have done the more difficult ramp.
Dog Swap.
Original Air Date: September 3, 2008
JD has Galaxy checked out by a vet to ensure she is still able to compete. The vet tells JD that there is no reason to remove her from activity. This week's theme was 'Loyalty'.
Dog Bone Challenge: "Tree Stump Stay"
Best in Show Challenge: "Me or Them"
The bottom three were Teresa & Leroy, JD & Galaxy, and Travis & Presley. Victoria Stilwell felt that both Teresa and JD were threatening in their stances when asking their dogs to stay. Presley was the only dog to break his stay, but Travis was able to regain Presley's attention. The decision from the judges seemed difficult to make, but ended up expelling Teresa, feeling that she'd lost sight of the meaning behind the loyalty challenge.
The Greatest American Dog Is....
Original Air Date: September 10, 2008
The top three face off in the final episode of Greatest American Dog. There was no Dog Bone challenge this week. There were instead two Best in Show challenges where someone was eliminated.
Best in Show Challenge: "Final Exam"
Best in Show Challenge: "Obstacle Course/Interview"
