Have you ever FaceTimed with your dog? It’s a great way to make face-to-face contact while you’re out of town and your dog is with a sitter.
Your dog almost certainly recognises your voice. But sometimes, it’s hard to tell whether or not they know what’s on a screen. Does your dog recognise you on a phone or tablet screen?
Dogs recognise faces, just not faces in motion
First things first: your dog probably does recognise your face in real life and in still photographs (source). But when images start moving, they get confused. One reason? “Flicker sensitivity.”
Flicker sensitivity is the rate at which an animal’s eye can record images and perceive motion. According to Dr. Stanley Coren, writing for Psychology Today, dogs have a higher flicker sensitivity than humans.
When you watch a video chat on your phone or tablet, your visual receptors process increases and decreases in brightness, and your brain identifies the person (or dog) in frame.
Dogs, with their higher flicker sensitivity, can’t pick out specific images in all those shifts in brightness and movement. It’s all a bunch of jerky lights and shapes to them.
Dogs take in visual information at least 25 percent faster than humans do. That means they’re great at detecting motion (think about how fast your dog whips her head around when she catches sight of a running squirrel)! But they have a harder time identifying moving images on screen.

Screen size matters
When it comes to whether or not dogs can recognise faces on a smartphone or tablet screen, size matters. Some dogs can recognise images on television, especially a modern high-definition set. But phone and tablet screens are much smaller, and the images are much more compressed.
Dogs’ eyesight evolved for hunting, so they’re better at seeing movement from a distance, and they have strong peripheral vision. In other words, they’re good at catching the basic, big-picture idea of the object or scene in front of them. But small screens and compressed data mean dogs can’t identify faces on phone or tablet screens.
If you have a jumbo-sized, high-def television monitor, your dog may be able to recognise you on a Skype call! But it’s unlikely they’ll know exactly what they’re seeing if you show them a person on an iPhone screen.
Sound matters more (but it isn’t perfect)
Even if your dog doesn’t recognise your face on an iPad, they may recognise your voice. Studies show that dogs recognise individual voices, and are far more responsive to tone of voice than specific words. So if you call your dog on the phone, remember to use a calm, positive voice.
However, as with images on a smartphone or tablet, sound through these devices is compressed. Also, dogs’ brains don’t work the way ours do; sometimes, they can’t connect the face and voice on screen with the flesh and blood human they love. Even the best-hearing dogs get confused by a disembodied voice coming from a device.
Of course, on-screen and audio recognition vary from dog to dog. Some dog sitters swear their canine clients perk up when they hear their owner’s voice over the phone! It all depends on the technology and the specific dog.
Smell is stronger than sight
If you’re going out of town, you can still set up a Skype date with your dog. Even if they don’t recognise you onscreen, you’ll get the satisfaction of seeing their cute, fuzzy face!
But offer your dog another option: leave your scent behind when you go out of town.
Dogs have amazing noses, with 44 times more olfactory receptors than humans. Appeal to their strongest sense, and remind them of you while you’re gone, by leaving behind a scented item from home. Bedding, a well-worn jumper, or even an old shoe gives your dog a sensory reminder of their person until you’re reunited.
The bottom line is, most dogs can’t recognise faces on phone screens or tablets. But that doesn’t mean you shouldn’t FaceTime or Skype with your pets while you’re out of town! It won’t harm them, and they may even recognise and be comforted by the sound of your voice. Plus, you get the benefit of seeing their adorable face while you’re away. It’s a win-win for you and your dog.
