From Monkey Island wiki
Piranha Poodles are a particularly vicious breed of poodle that guard the Mêlée Island Governor's Mansion in the first game. Guybrush drugs the dogs by placing a yellow flower inside a piece of meat and throw it to the dogs. This causes the game to give a message to the player that assures that the poodles are "not dead, just sleeping".
The poodles are mentioned but not seen in the fourth game when Charles L. Charles reveals that he is running for the governor's office. Guybrush also mentions them again when talking to Stan about his time-shares; when Guybrush tells that he needs to talk to his wife about it, Stan understands that he doesn't want to end up in the doghouse, to which Guybrush comments: "Yeah. I mean, where would the piranha poodles sleep?"
Another reference to these poodles is when Charles L. Charles bursts in and Elaine threatens him by saying "Get out or I'll sic my piranha poodles on you!" In the fifth game, LeChuck reveals that he has his own school of piranha poodles, which he set on Guybrush sometime prior. Guybrush manages to elude them before confronting LeChuck on his ship. Later, the Marquis De Singe mentions that he was accused of cross-breeding the Queen's poodles, which can be another reference to the Piranha Poodles.
- The notice in The Secret of Monkey Island about the dogs not being dead, just sleeping, is likely a play on the famous Monty Python "Dead Parrot" sketch.
- The Piranha Poodles are referred to as "a school", like fish, rather than as "a pack", as dogs are typically called.
