Pet Rules for Dungeons and Dragons

Wrylyn had raised Dot since she was small enough to hold in one palm. The small dot of yellow fur on her head poking out of his sleeve when she was hungry. She’d often kept him company on watch, and rode in his hood during their travels. She loved to steal off his plate, holding her treat in her hands as she scampered out of arm’s reach. With her large eyes, and her little horns she was always up to mischief. As Wrylyn watched the fireball blossom around him, he dreaded his wounds, but he was more terrified by the stillness in his hood.


Pets are a feature in most people’s lives. Dungeons and Dragons creates a platform where the only limit to your pet is your creativity and your DM’s patience. If a campaign runs long enough, it’s likely that some member of the party will adopt a sugar glider that breathes fire, or a rat with gills, or a snake with one bad leg. It’s going to happen, but it opens a whole new problem for the party.

These creatures aren’t warriors. They don’t have the health or attacks of mounts or beast companions. As a result, the first time they are caught in an attack, they’re likely to die outright. Typically, these deaths are undramatic and only bring down the energy at the table. There is no drama, because characters have no ability to protect their pets, and without options there can be no tension. No one wants to see a pet die, the DM typically doesn’t want to kill the pet either, but massive damage (PHB 75-76) alone would be enough to kill a creature with only 1 or 2 HP.

This is the problem these rules attempt to fix.

Disclaimer. If you like to watch pets die, this supplement probably isn't for you.

The Power of Love

Love is a powerful force, it brings people together across great distances and drives them to great lengths. When a pet is loved, this love grants them certain protections.

  • Each player has a “Pet Attunement Slot” which can be filled by any creature with CR ½ or lower. To attune to a pet, the character must spend a total of 8 hours training their pet (using appropriate DC Animal Handling checks based on the animal, and skills being taught). This attunement slot represents the room the character has in its heart for the animal. A character is assumed to have a minimum of 1 Pet Attunement Slot unless otherwise specified by the DM. Once attunement is complete, a character is considered a pet’s “Master.”

  • Being attuned to a master grants a pet several advantages:

    • The pet is immune to the massive damage rule when the damage comes from an enemy spell, attack, or trap not specifically aimed at the pet. (This would not cover something like falling off a mountain or bridge. Additionally, pets should not be fighting with their masters, so attacks specifically directed at them can kill them.)
    • When a pet reaches zero hit points they fall unconscious and begin to make death saving throws at the start of their master's turn. They make throws in the same manner a player would.
    • Pets gain a bonus to death saving throws equal to ½ of their master’s wisdom score rounded down.

Optional Rule: Healing

Understandably, many players will feel that using an entire potion to heal a pet is a waste of a resource. The point of these rules is to allow players to bring their pets with them on the adventure, rather than play kennel simulator to keep their pets safe. So, in this optional rule, when a pet takes enough damage to render it unconscious a player may administer a portion of a potion to it rather than an entire potion. The details of this are explained below in the “Doses Per Potion by Size” section. When a potion is administered in this way, two things happen:

  • The potion is rendered useless to players, but retains its other doses for use with the pet.
  • The pet regains 1 HP and is no longer unconscious.
