One pet, and only one
Exactly one pet belongs in the upload. Two animals on a sofa, a person hugging a dog at equal size, or a collage of past photos gives the scene more than one candidate. The performance has a single body in front of the camera. If the still argues about which body that is, the result has to guess, and the guess can switch midway.
A person may appear small in the background of an otherwise clear pet photo, but the pet should dominate the frame. This page has no second slot for an owner, a friend, or another animal. If you want two pets to have a turn, make two clips. Each one needs its own still, its own coat, and its own review.
Show the face, the coat, the body
The useful photo is the one where you can name the pet without squinting. Eyes, muzzle, ears, and the main blocks of color should be visible, and the body should not be a rumor under a blanket. Bad Times AI has to carry that appearance through a long expressive performance. A face-only crop asks the scene to invent the rest.
Lighting can be plain. A dark room, a strong backlight, or a filter that smears the coat removes the very information the role needs. If the animal is wearing a bandana or a sweater, include it on purpose, knowing small patterns may soften. The coat color and the large markings matter more than a tiny tag.
