Answer: Philip, his bulldog
As Quartermaine's minion, Philip is intent upon squaring off with Gromit just as his master is focused on thwarting Wallace. This is his (and Quartermaine's) tragic flaw, however, mistaking Wallace as the more fearsome adversary. The result is that both Philip and his master are caught off guard. Philip - initially a pointer at the beginning of production, was transformed into the more iconic British breed by producers. Growbag, and Thripp are minor characters in the film. Hutch is the name of a rabbit who figures prominently in the plot, but not as Quartermaine's chum. The voice of Victor was provided by Ralph Fiennes, who went on to the starkly contrasting film "The Constant Gardner".
