Lesser Dog

 is a monster encountered in Snowdin Forest. It is later found as an NPC in Grillby's. It is a member of the Royal Guard.

Appearance
Its fur is completely white and its red tongue appears to be perpetually lolling out of its mouth. It wears gray, presumably metal armor with a darker gray band around the waist area. It holds a sword and a shield with the Delta Rune.

Personality and traits
Like several other dog characters, becomes overexcited from physical attention. It is capable of extending its neck at a seemingly limitless rate when stimulated by being pet.

While waiting around its sentry post in Snowdin forest, spends a lot of its time making snowdogs, mostly with necks in similar lengths to its own. A faun monster standing near the post notes that it seems to get overexcited in the construction of the figures and never finishes them. It may be that expends some of its excitement in being pet, as after being pet by the protagonist its statues will become more complete, and the more pets it receives the more statues it will make around its sentry post - on the flip side, if it is killed, its sentry post will be accompanied only by a pile of formless mushy snow.

appears to enjoy spending its time off sentry duty by playing card games (namely poker and go fish) against itself at Grillby's; however, judging by its regular failure even against itself, it may not be very good at the game.

Interestingly, is never mentioned by the other guard dogs. Killing him provokes no reaction from the other dogs at Grillby's. In turn, if is the only guard dog left, how he acts at Grillby's does not change.
