Defender
, Sacrifice this creature: Target creature you control gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy it.)
A friend in good times, a guardian in bad times, and a savior when all else fails.

Resolute Watchdog can be the target of its own ability. The ability won’t resolve since it won’t have a legal target, and no creature will gain indestructible, but this does allow you to sacrifice Resolute Watchdog without another creature to target if you want to.
