Bicep Heart Dog & Cat: Make Your Pet Flex

Short answer: Upload one clear, full-body photo of your dog, cat or other pet to the generator. The AI makes your pet stand on its hind legs, flex one front leg like a bicep and curl the other paw against it into a rough heart, all with a dead-serious face. You get a 7-second 9:16 video in about 3–5 minutes, at the same price as a video of a person.

What the pet version looks like

The pet follows the same beats as the human bicep heart trend:

1. Stands up on its hind legs, front paws together, looking at the camera with a straight face.
2. Crosses one front leg over its chest so the paw touches the other front leg.
3. Flexes the other front leg up at the elbow, paw next to its head, like a proud bicep flex.
4. Curls the crossing paw against the inside of the raised leg, so the two legs make a rough heart.
5. Holds the pose with a serious, proud look and a small head tilt.

Your pet keeps its species, breed, fur colour, markings and face from the photo. The scene is a bright, clean living room, not your own background.

Which pet photo works

• The whole animal in the photo, from ears to paws, so the AI gets the legs, body and size right.
• The face clearly visible, looking roughly toward the camera.
• A sharp photo in good light. Fur colour and markings come from the photo.
• One animal only. Two pets, or you together with your pet, are not supported. Make separate videos instead.
• Any species can be tried, but results are best with cats and dogs.

A free photo check runs right after upload, before you pay. It tells you if it can't find a pet or finds more than one subject.

Price and options

Pet videos cost the same as people: $9.99 for 1 video, $14.99 for 3 videos or $29.99 for 10 videos, one-time payment, no subscription. See pricing. There are no muscle options for pets. The Normal, Buff and Extreme arm choices apply only to people.

The output is the same as for a person: a 7-second 9:16 720p MP4, silent and without a watermark, plus a GIF export. Add the trend sound when you post on TikTok or Reels.

An honest note about paws

Paws cannot curl like a human hand, so a pet's heart is rougher and less exact than a person's. That is part of the joke: a serious dog or cat trying its best to make a heart. If you want a sharp, clean heart, use a photo of a person and read the pose guide.

If a finished video clearly shows a different animal, the body is visibly broken, or your pet is missing, email support@bicephearts.com within 7 days. We review it manually; if we approve the claim, you get one free re-generation for that video (not a money refund). A failed generation returns its credit automatically.

FAQ

Can my dog do the bicep heart?

Yes, as an AI video. Upload one clear, full-body photo of your dog and it stands on its hind legs, flexes a front leg and curls the other paw into a rough heart with a deadpan face.

Does the bicep heart work with cats?

Yes. Cats and dogs give the best results. Use a sharp photo with the whole cat and its face visible.

Can I be in the video with my pet?

No. Each video shows one person or one pet. Upload a photo of only your pet, and make a separate video of yourself if you want both.

Is the pet version more expensive?

No. Pet videos cost the same as videos of people: $9.99 for 1 video, $14.99 for 3 videos or $29.99 for 10 videos.
