Transcript for 'Downward Dog' cast on how they first started the show 'just for fun'
50 years after "Mr. Ed" the sit come starring a talking horse comes a sit come with a talking dog but this is not all right standard every day affair. It's funny how life works. Yes there's a talking dog called martin this is ground breaking television. Number one the dog is depressed. I don't feel very respected as I being. It is a talking dog show for adults. I don't want to come off as, like, hyper critical but we used to go on walks. People are like the whole family could watch it, I'm like not really. I watch it with my eight-year-old kid but I'm a bad parent. Obviously you're a terrible parent but that's fine. This is a funny comedy here on network television on ABC. What's the name. I'm Nan. No the dog what's the dog's name. I don't know if I would have gone and done a regular sit come no matter how good it was. I like how this is different. That's Allison of of Fargo. She plains martin's owner, Nan, and that's cocreator and voice of martin. A lot of my in flaws are part of his character, a way to make fun of myself and the whole generation, very self-analytical. So martin has to sit through sex. Yeah. Yeah. Everybody who has dogs who has sex you know how it is. It's weird you look over and your dog is looking at you. There's Ned he is a rescue from Chicago. Hey Ned this is my yard, Ned. Certainly when I first read the description of the show I thought oh, dear. If something makes me happy, how could it be wrong. Made this web series just for fun. I was an in ad director. And always did long-form stuff. TV folk got hold of it, loved it and took a risk. Yeah I'm a trash dock dog and she's a fancy lady but we have each other. For "Nightline," in los Angeles. Thanks Nick. Downward dog airs Tuesday here on ABC. Thanks for watching "Nightline"
