How do I add the Singing Pet sound so it lines up?

Updated: October 23, 2026

Short answer

Download the silent version, open TikTok, tap Add sound and pick the trend's sound (shown as “original sound – reggie”). Start it at 0 seconds. The video follows the viral clips' timing, so the high notes and the finale line up.

Example frame: a dog throwing its head back on a high note

Why it lines up

We built the video from the timing of the viral clips, which are all 10 seconds long. The mouth moves on the same beats, so the sound fits without trimming.

If it drifts

Make sure the sound starts at 0 seconds.
Use the silent download so two tracks do not clash.
Nudge the sound by a few frames in the editor if needed.

How to add the original sound in TikTok

Our videos come with an AI-made original soundtrack. To use the trending sound instead, add it inside TikTok when you post. You can also download a silent version from My videos and put the original sound on that.

Open the original video of this trend in TikTok, tap the sound name at the bottom, then tap Use this sound.
Tap Upload and pick the video you downloaded from us.
Open Volume and turn the video's own sound down to 0, or download the silent version from My videos.
To line up the beat, use the scissors (trim) to start the sound from 0 seconds, then post.
