Many dog owners have witnessed this kind of behavior, and recent research supports what dog lovers have long suspected — dogs can indeed feel jealousy.
While they may not understand the word jealousy, dogs are very perceptive when it comes to changes in attention and affection. When someone else becomes the focus of your attention, your dog may see it as a threat. They might start behaving in ways that clearly show they want your attention — demanding to be petted, interrupting a hug with your partner, or trying to squeeze between you and another pet. These are not just quirks — they’re emotional signals.
Some dogs express their jealousy more assertively. This doesn’t necessarily mean they’re being aggressive, but rather emotionally reactive to something they don’t quite understand. They may growl at another dog, try to push them away, or become overly protective of you. Other dogs might respond more quietly — withdrawing, refusing to eat, or appearing sad and disinterested. It’s their way of saying something doesn’t feel right.
Some dogs regress to puppy-like behavior when they feel left out — urinating indoors, chewing on shoes, or creating messes around the house. While this might seem like mischief, it’s often a cry for attention. Once you look at it from the perspective of emotional insecurity, it becomes clear what your dog is really trying to communicate.
If you’ve noticed this kind of behavior, the good news is that there are ways to help. First and foremost, it’s important to reassure your dog that they haven’t been forgotten. Even brief moments of one-on-one time can make a big difference. When introducing new people or pets into your dog’s world, do it gradually and with lots of positive reinforcement. This way, your dog will learn that they’re not losing your love — you’re simply sharing it a bit more.
Of course, if the behavior escalates or becomes problematic, it’s a good idea to consult with a veterinarian or a dog behaviorist. Sometimes, jealousy is just the tip of the iceberg, and a professional can help you get to the root of what your dog is experiencing.
At the end of the day, our dogs aren’t just companions — they’re emotional beings, full of instinct, love, and a deep desire to belong. If your dog shows signs of jealousy, it means one thing above all: they love you and don’t want to lose their special place in your life. And that might just be the purest kind of love there is.
