Yes — one. A photo with a pet is among the few additions that reliably helps, and it's one of the easiest conversation openers you can hand someone.
Why it works
- It's a free opener. People who can't think of a first message will ask about the dog. That alone justifies the slot.
- It signals responsibility. Keeping an animal alive and happy is legible information about you.
- It relaxes your expression. People photographed with their own pet stop performing. It's often the most natural photo in the set.
The one way to get it wrong
Making the pet the subject. A close-up of your dog with you barely in frame — or worse, a photo of just the dog — wastes a slot. Someone is deciding whether to talk to you, and you've shown them an animal. Be clearly in it, face visible, ideally interacting rather than both facing the camera.
One, not a gallery
One pet photo is charming. Three makes the profile about the animal, and reads as having little else to show.
Borrowed dogs
A photo with a friend's dog is fine — you don't owe anyone a disclosure that you're not the owner. Just don't build an identity on it, because 'you don't have a dog?' is a bad first in-person moment over something that was never load-bearing.
