Care
Comfort and care before, during, and after a scene. This can be as little as making sure they drink fluids while in headspace, avoiding allergens, taking cool-down periods so they don’t overexert or overheat, providing emotional support after a scene while coming out of headspace, or even grooming.
Protection
Keep scenes and spaces Safe, Sane, and Consensual. Stop a scene if you have to. Pups/pets/critters can cut themselves or chip a tooth when playing too hard — direct the scene when you can, and prepare the room before they get rambunctious.
Headspace
When entering or in a scene, the Handler should treat and address the pup/pet/critter as they would the animal - not as a hooman posing as an animal. There are limitations, of course. At the end of a scene, provide for them while they’re reasserting their hooman selves. Sometimes this is an emotional or sensitive time - be attentive.
Interaction
Pups, pets, and critters get bored when there is nothing to do. Play with them (be gentle; you do not want to tug too hard on a toy and break a tooth). Give them love, attention, scritches, pets, belly rubs, and treats. Train them if you would like. Let them puddle on you and give them cuddles. Let the animal they identify with in headspace guide how you play, within their limits and consent. Learn their personality and have fun!
