PetLeash automatically walks the dog.
PetLeash ensures that you always have a non-combat pet summoned. It will select a random pet from a list that you choose. It tries its best to not summon a pet while you are busy, and detects quests that would interfere with summoning a normal pet. It also can automatically unsummon a pet when you stealth or go invisible.
As of 1.5, PetLeash now allows you to alter the likelihood of a pet being summoned. Additionally, you can set up certain pets to be summoned in certain locations.
PetLeash also provides a LibDataBroker plugin that you can use to quickly summon specific non-combat pets.
Commands:
/petleash enable : enable/disable auto-summoning
/petleash togglePet : summon or desummon pet (and switch auto-summoning)
/petleash resummon : summon a new pet
/petleash desummon : desummon pet
/petleash config : show configuration
PetLeash has several key bindings that can be set via the Blizzard Key Binding interface.
