Foo dog

Foo dogs were the most commonly encountered of the foo creatures.

Description
Like all foo creatures, foo dogs were four-legged beasts with large, flat heads and big eyes,  with leonine bodies about three or four feet long. They had long, floppy ears and broad noses. Their tails were short   and ended with bushy hair. Their thick fur was usually gold or black,   but other varieties    &mdash;such as white, gray, or even green or purple&mdash;were known.

Abilities
Foo dogs had all the supernatural abilities of other foo creatures. When they barked consistently for over a minute, the thunderous sound would occasionally summon one to six additional foo dogs to their aid. Foo dogs were very intelligent.

Personality
Foo dogs had similar personalities to other foos. Foo dogs and foo lions did not usually associate with each other, though they had no hatred towards each other.

Combat
Foo dogs attacked with tooth and claw, which caused more harm to evil creatures than non-evil ones.

Society
In their extraplanar homes, foo dogs lived as mated pairs or in packs. They spoke their own language and the language of foo lions. They could also speak the languages of those humanoids with whom they frequently interacted.

Ecology
Foo dogs ate all manner of inorganic material, including gems and precious metals, especially enjoying silver and platinum.
