I wrote Dug as a combination of all the dogs I’ve owned. Marcella, Precious, Rosy, and Ava are all in there. The distractibility of Dug (SQUIRREL!!) is based on a game I’d play with my dogs. On a hot day the dogs would be panting to cool themselves down. So, I’d jump in and pant along with them. Then I’d stop abruptly and pretend I’d seen something important. The dogs would do the same and go to attention along with me. Long pause. Then, everyone back to panting. It was hilarious. Also I’ve noticed that dogs have an amazing capacity to give love immediately to people that they meet for the first time. Hence the line “I have just met you and I love you.” Dug says this to our old man character, Carl, when they first meet. It’s a challenge to Carl accept his new “family” who loves him and needs his attention. That line was also born out of something a camper said to me when I was a camp counselor in college. The kid had just met me but his first words were “you are my counselor and I love you.
