Make a caption sound like your pet

Pair one short line with a detail people recognize: their name, a favorite sleeping spot or an expression they make. For example: “Midnight mood, afternoon nap. Milo has already retired to the sofa.” Avoid repeating a long block of hashtags after every post; one clear caption is easier to read.

Add useful alt text

Describe what is in the picture instead of repeating the caption. An example is “AI-created portrait of a golden retriever wearing a pumpkin costume on an autumn porch.” Change the breed, coat color and setting to match your own image. Alt text helps someone understand the picture when they cannot see it.

Posting an AI Halloween pet portrait

Keep the caption playful while making the medium clear. Add “AI-created Halloween portrait from a photo of Luna,” for example. Review the face, paws and markings before publishing. A generated portrait is a creative interpretation and should not be presented as a real costume photo shoot.
