Trooper

Trooper comes from French troupier, from troupe (group, troop), ultimately from Old French troper (to assemble). As a word it refers to a soldier or cavalry rider, but in everyday American English it has evolved to mean someone who endures difficulty without complaint — a reliable, uncomplaining companion.

Trooper is a name that honors a pet's resilience. It is often given to dogs who have come through something difficult — a health challenge, a rough start in life, a long journey to find their home — as a permanent recognition of what they have survived and who they have become. The name carries genuine respect: a trooper is someone you can count on, who does not complain, who shows up every day and gives everything. It is one of the most genuinely affectionate names in this list, because it says as much about what the pet means to their owner as it does about the pet themselves.
