Sweetie

Sweetie, better known as Sweetheart, is a dog that Frank got when his dad told him that he ran over his old dog Nutty with his car. He was named after Susan, as Manny thought he should be named after an animal, saying "Zeeb" for short. Rodrick also wanted to name him an animal, turtle so he could call him "Turd" for  short. Rodrick then bought Sweetie a bowl that said Sweaty on it. Greg says that's what they get for sending the family's worst speller on errands.

He got on Greg's nerves a lot and likes to sleep on his bed, right in the middle of it. He also barked at the TV all day until a commercial with gophers comes on, stopping Greg from playing video games or watching TV.

Frank could tell that Greg grew tired of it, so he gave Sweetie to his grandmother.

Appearance
In the online version, Sweetie appears much smaller, with beady eyes, and a rough coat. He has a black nose, which is usually wet, and is a small breed. In the book version, his appearance is somewhat bigger, but mostly the same.

In Cabin Fever, Sweetie had gained so much weight that he is decepted as having his feet hanging off the ground in the illustrations. According to Greg, he now looks like "a tick that's about to pop"

Personality
Sweetie is both lazy and mischievous. As shown as he lies around all day, and when he made Greg chase him through the neighborhood in his underwear. Sweetie doesn't take a liking to most people, mostly for what they do to him, like Frank, who constantly seeks his attention and annoys Sweetie to no end. He usually dawns over the comfort of Susan, even though she doesn't like Sweetie as much as Frank does.
