Also, once things inevitably fall apart, Wallace's "GROMIT! HELP! DO SOMETHING!," or the less emphatic "Gromit! Do something, lad!" There's no ceiling on how many times Wallace will say this in a single episode.
Civilized Animal: He's bright and perceptive, but is treated as an ordinary dog. He also seems to have the psychology of a dog, if his devotion to Wallace is any indicator.

Wallace: Relieved to have come out of this in one piece. Gromit: Instead of several hundred, like Preston. - G
The Engineer: Often has to build and use the inventions that Wallace dreams up.
Disproportionate Retribution: She lost her job as the Bake-o-Lite bakery spokeswoman when she became too heavy to use the balloon featured in all their commercials. Because of this, she decides to murder a baker's dozen worth of bakers to punish all bakers for producing the fattening foods that she got fat eating.
Family-Unfriendly Death: Being eaten alive by crocodiles at the zoo, after she weighs down the balloon on which she's attempting to escape.
Hurricane of Puns: She makes many, incredibly unsubtle jokes on how she's going to murder Wallace.

Jerkass: He locks up anyone (and anything) that he considers to violate the law. The main plot of The Bogey Man involves him trying to close the local country club mostly because he wasn't invited to it.
Bitch in Sheep's Clothing: He opens up a fundraiser on the claims of rebuilding a dog shelter. It's actually a scam to swindle money out of the townsfolk and using actual strays as labor for the rides.
