# How to Act Opposite a Child or an Animal (On Stage and On Set)

> The old line says never work with children or animals. Here's how to do it well: why they pull focus, how to know your lines well enough to adapt when a cue changes, who's really in charge of a dog or a young actor on set, and what changes for blocking and takes.

You've got the part. Then you read the breakdown again and see it: your scene partner is eight. Or your scene partner is a terrier named Biscuit, and he comes with two trainers and a bag of chicken.

Someone in the cast will quote the old rule within the hour: never work with children or animals. Everyone laughs. Nobody tells you what to actually do on Monday.

The short version: know your lines so well that you can play them off whatever you're given, because the cue won't come the same way twice. Treat the trainer, the parent, the chaperone, or the studio teacher as part of the scene, not an interruption. Plan your blocking around what the child or animal can repeat. And stop trying to compete. Play with them, and the scene gets better.

## Why the old rule exists (and what it gets wrong)

The line is usually pinned on W. C. Fields. Barry Popik, who traces the history of sayings, found that it [can't be originally credited to Fields](https://barrypopik.com/blog/never_work_with_children_or_animals_show_business_adage). His earliest example is a 1931 *Milwaukee Journal* piece saying many stars wouldn't appear with animals or children, believing that "no adult can compete."

That's the real fear: being upstaged. A dog scratching its ear or a five-year-old staring at the camera pulls every eye in the house. They aren't acting, so they look completely real.

What the rule gets wrong is the fix. Competing for attention is a fight you lose. The actors who come off well do the opposite: they stop performing at the child or animal and start reacting to them. When your scene partner is unpredictable, your job is to be the steady one who notices everything.

## Know your lines cold, so you can let go of them

An adult scene partner gives you the same cue, more or less, every time. A child might paraphrase, speed up, trail off, or answer a line early. A dog might bark through your speech or wander off its mark. If your lines depend on hearing the exact cue the exact way, you'll freeze.

So learn your lines past the point of recall, to the point where they come from the situation. Research by Helga and Tony Noice, summarized by the [Association for Psychological Science](https://www.psychologicalscience.org/observer/to-be-or-or-um-line), found that actors learn lines by focusing on meaning, breaking scripts into logically connected beats or intentions. Good actors feel the intention in reaction to what the other actors do. That's exactly the skill you need here: if you know why you're saying the line, you can say it after any cue.

Learn the shape of the other person's lines too, not just their words. Know what the child's character is trying to tell you, so if the words come out wrong, you still know where the scene is. Our guide to [listening on stage](https://www.offbook.com/blog/how-to-listen-on-stage) has more on reacting to what you get instead of waiting for what you expected.

Practice with a cue that won't behave. If you work in Offbook, you can set how fast the other voices read and add a pause before any line. Change the speed and pauses between runs so the cue doesn't arrive on the beat you've memorized, and turn on auto-advance so the scene moves on if you dry up. The video below shows those pacing controls.

## Read a scene the way a child actor might play it

Shakespeare wrote a sharp child part in *Macbeth*. Lady Macduff's son gets the better of his mother in a fast exchange shortly before the murderers arrive:

> **LADY MACDUFF:** Sirrah, your father’s dead.
> And what will you do now? How will you live?
>
> **SON:** As birds do, mother.
>
> **LADY MACDUFF:** What, with worms and flies?
>
> **SON:** With what I get, I mean; and so do they.
>
> **LADY MACDUFF:** Poor bird! thou’dst never fear the net nor lime,
> The pit-fall nor the gin.
>
> **SON:** Why should I, mother? Poor birds they are not set for.
> My father is not dead, for all your saying.
>
> **LADY MACDUFF:** Yes, he is dead: how wilt thou do for a father?
>
> **SON:** Nay, how will you do for a husband?
>
> **LADY MACDUFF:** Why, I can buy me twenty at any market.
>
> **SON:** Then you’ll buy ’em to sell again.
>
> *William Shakespeare, Macbeth, Act IV, Scene II*

Now imagine you're playing Lady Macduff. One night, the boy pauses before *As birds do, mother*, and you can see him searching. Another night, he rushes *Nay, how will you do for a husband?* and steps on your line. If all you have is the words, either moment throws you.

If you know the scene is a game between them (she's testing him and grieving, he's refusing to believe her and winning anyway), you have somewhere to go. The pause becomes him thinking it through, and you can let him. The rushed line becomes him being cheeky, and you can laugh. You can read the full scene in our [Macbeth page](https://www.offbook.com/plays/macbeth).

## When something unexpected happens mid-scene

It will. The child forgets a line or giggles. The dog looks into the wings. Here's what to do, in order.

- **Stay in the scene.** Don't break and look to the director first. A real person in that moment would react to what just happened, so react to it.
- **Use it if you can.** A child who giggles can be a child who giggles in the story. On stage, call a wandering dog back only with the cue the trainer taught you. On set, let the handler take it back.
- **Give a child the line inside the fiction.** Ask the question that their line answers, or say what they were about to say as your own thought. Our guide to [covering when a scene partner forgets a line](https://www.offbook.com/blog/scene-partner-forgets-a-line) walks through this.
- **Let the trainer take an animal back.** Don't improvise new commands to a dog you don't handle. The person who trained it knows what cue it's waiting for.
- **Keep the next line ready.** Once the scene is back on track, your line has to be there.

On stage, an animal can't save you if you get it wrong. Bill Berloni, who trained the original Sandy in *Annie*, told [Playbill](https://playbill.com/article/he-trained-the-original-sandy-from-annieand-made-an-entire-career-out-of-it) that a dog given the wrong cue can't think, "I'll cover for him." Hold a treat in the wrong hand, and the dog may head for the wrong side of the stage.

## Work with the trainer, the parent, and the chaperone

A child or an animal never arrives alone, and the adults with them aren't in the way. They're how the scene works. Get to know them early, and ask how they'd like you to help.

### On stage with an animal

In theater, you may become the trainer. In a 2022 [BroadwayWorld interview](https://www.broadwayworld.com/san-diego/article/Interview-Animal-Trainer-Bill-Berloni-Helps-Shelter-Dogs-Become-Stars-of-the-Stage-in-ANNIE-at-Broadway-San-Diego-20221227), Berloni says he trains the actors to give the commands, and that he runs through the cues with an actor before casting is final. With dogs performing eight times a week, he says, there has to be positive reinforcement.

He also told Playbill he started insisting that actors onstage with the dog love animals and take extra time to build a bond. An actor who doesn't, he said, gets a dog that responds to the treat, not to the performance. So spend the time: feed, walk, and play the way the trainer shows you, as often as they'll let you.

### On set with an animal

On film, the animal may be watching its trainer, not you. In a [Fresh Air interview](https://www.tpr.org/2015-07-29/a-hollywood-animal-trainers-secrets-for-getting-dogs-to-act-on-cue), trainer Teresa Ann Miller (who worked on *White God*) said a dog's behavior reflects her body language and tone of voice. To get a sad, lost look, she speaks slowly and softly while a co-trainer shuffles their feet to draw the dog's gaze. Expect people moving and talking just off camera during your take. That's the animal's cue, not a distraction to complain about.

On productions American Humane monitors, its [cast and crew guidelines for filmed media](https://www.americanhumane.org/publication/production-cast-and-crew-guidelines-for-filmed-media/) say cast and crew may not pet, feed, or play with animals off camera if the handler or American Humane's safety representative thinks it's unsafe or not in the animals' interest. They also ask cast and crew to limit "distracting motions, noises and smells," naming food and perfume. And the handler can clear non-essential people from the set during animal stunts or intense action. In practice: ask before you touch, skip the perfume, and keep snacks away from the set.

### With a child

Child performers come with adults whose job is the child, and they outrank your scene. The rules depend on where you're working. In California, Title 8 of the state's Code of Regulations says a parent or guardian of a minor under 16 must be ["within sight or sound"](https://www.dir.ca.gov/t8/11757.html) of the child at all times on the set or location. A [studio teacher](https://www.dir.ca.gov/t8/11755_3.html) there is responsible for the health, safety and morals of minors under 16, watches for signs of fatigue, and may refuse to let a minor work or remove them from the set if conditions put the minor's health, safety or morals at risk.

In England, under the Children (Performances and Activities) (England) Regulations 2014, a licensing authority approves a chaperone to ["have care and control of the child"](https://www.legislation.gov.uk/uksi/2014/3309/regulation/15/made) during a performance or rehearsal, unless a parent, or a teacher who would ordinarily provide the child's education, is caring for them. Other places have their own rules; the production will know them.

What it means for you: when a studio teacher or chaperone says the child is done, believe them; the scene stops. Be ready on the first takes the child is in, be the same friendly person every day, and don't take over a parent's job.

## Build the relationship before the cameras roll

One thing that helps: spending time with the child as themselves before you play the scene. Before the Room scenes in *Room* were shot, Brie Larson and seven-year-old Jacob Tremblay met for over three weeks to build a close relationship, according to co-star Joan Allen, as cited in the film's [production history](https://en.wikipedia.org/wiki/Room_(2015_film)). By the time they played mother and son, the trust was already there.

You won't always get three weeks. Use the breaks: play a game, ask about school, learn what makes them laugh. A child who likes you will look at you in the scene.

Some directors go further and shape the shoot around the child. Steven Spielberg shot *E.T.* in roughly chronological order to get convincing emotional performances, and skipped storyboarding much of it to allow spontaneity, according to the film's [production history](https://en.wikipedia.org/wiki/E.T._the_Extra-Terrestrial). You don't control the schedule. But you can bring the same idea to each take: let the child's moment be real, and answer it.

## What changes for blocking and takes

Plan everything around what the child or animal can do reliably, and take the flexibility on yourself.

- **Keep their blocking simple.** A dog's mark may be where the trainer can reach it. A small child's cross may be one clear move to one place. You make the adjustments around them.
- **Hit your own marks precisely.** If they drift, you're the fixed point the camera can find. Our guide to [memorizing blocking](https://www.offbook.com/blog/how-to-memorize-blocking) helps.
- **Expect the day to bend around them.** A child's working time is set by the rules where you shoot, and an animal's attention runs out. Their best moments may come early, so be warmed up and ready from the first setup.
- **Give the same energy off camera.** When the camera is on the child, your reading is their scene partner. Play it fully, every time.
- **Accept that the best take may be theirs.** The editor may pick the take where the dog looked perfect, not the one where you did. Make every take one you'd be happy to see used.

## Questions actors ask

### How do you act with a child actor in a scene?

Know your lines and the scene's meaning so well that you can respond to whatever the child gives you. Spend time with them off camera so they trust you, keep your own blocking precise so they have a fixed point, and work with their parent, chaperone, or studio teacher instead of around them.

### How do you act with a dog on set?

Follow the trainer. On film, the dog may take its cues from a trainer just off camera, so expect movement and voices there during your take. Ask before you pet or feed the dog, and keep perfume and food smells away. On stage, you may be taught to give the commands yourself, so learn them exactly.

### What if the child or animal does something unexpected mid-scene?

Stay in character and react to it as your character would. Use it if it fits the story. Help a child back to their line inside the fiction. With an animal on stage, use only the cue the trainer taught you; on set, let the handler bring it back. Never invent your own commands.

### Should I bring my own dog to set to practice?

No. American Humane's cast and crew guidelines discourage bringing pets to a filming location. A set is full of hazards for animals, and any pet that comes must be contained and supervised. Pets aren't allowed on the set where working animals are or will be.
