Do Dogs Get Jealous? Understanding Dog Emotions and Behavior

Do Dogs Get Jealous is a core question countless dog owners keep asking: when a dog wedges himself between a hugging couple, whines when you’re holding a newborn, or lets out a low growl as another dog gets a friendly pat, it all looks a lot like “jealousy.” 

For decades, the scientific community was cautious about labeling such a complex “secondary emotion,” wary of projecting human feelings onto animals. Yet as research on canine emotion and cognition advances, views are shifting. A growing body of experimental evidence and extensive real‑world reports indicates that the states dogs display are functionally equivalent to jealousy—so, in practical terms, the answer to Do Dogs Get Jealous is very close to “yes.” 

Below, we’ll outline the scientific evidence, the clear signs to watch for, common triggers, and humane, actionable strategies to manage the behavior, helping you maintain a more harmonious multi-pet or family household.

Do Dogs Get Jealous? The Scientific Verdict in Pet Behavior Psychology

From a pet behavior psychology standpoint, understanding dog emotions helps explain why dog behavior emotions around social rivals are functionally similar to jealousy. In humans, it's a complex emotion involving social comparison, fear of losing a valued relationship, and sometimes even feelings of betrayal or resentment. Do dogs possess this level of abstract thought? Perhaps not in the exact same way. However, research increasingly supports the idea that dogs experience what scientists call "proto-jealousy." This is a more fundamental, primal version of the emotion, rooted in the instinct to protect a valuable social bond or resource from a rival.

A landmark study that shifted the conversation was conducted by researchers at the University of California, San Diego, and published in the prestigious journal PLOS ONE. In this experiment, dogs showed significantly more jealous behaviors (like pushing, whining, and trying to get between their owner and an object) when their owners gave affectionate attention to a stuffed, animatronic dog than when they paid attention to a non-social object like a book.

For a deeper dive into this foundational study, you can read the full paper on the PLOS ONE scientific journal website.

This study was pivotal because it suggested that the behavior wasn't just about the owner's attention being diverted; it was specifically triggered by the owner's interaction with what the dog perceived as a social rival. This aligns perfectly with the core components of jealousy. From a pet behavior psychology perspective, this makes perfect evolutionary sense. In a pack environment, access to key figures (like the pack leader, or in this case, the human owner) means access to resources, safety, and reproductive opportunities. Protecting that bond from an interloper is a powerful survival instinct.

So, while your dog might not be contemplating the nuances of your relationship with your new partner, they are very likely experiencing a potent emotional cocktail of anxiety, exclusion, and a primal urge to reclaim their position as your primary focus.

Dog Jealousy Signs: How to Read the Behavior

Jealous behavior in dogs isn't a single action but a spectrum of behaviors designed to interrupt an interaction and redirect attention back to themselves. Recognizing these signs is the first step toward addressing the underlying emotion.

Here are the most common dog jealousy signs:

  1. Intrusive Physical Contact: This is the most classic sign. The dog will use their body to physically intervene. This can include pushing their way between you and another person or pet, nudging your hand away from the "rival," or leaning heavily against you to claim your space.

  2. Increased Vocalization: Whining, whimpering, or insistent barking that only occurs when you are interacting with someone or something else is a clear bid for attention. The dog has learned that noise often gets a response.

  3. Aggressive Displays: This is a more serious manifestation and requires immediate attention. It can range from a low growl or a lip curl to outright snapping or lunging at the person or pet you are showing affection to. This is a clear signal that the dog feels threatened and is trying to drive the rival away.

  4. Attention-Seeking Antics: Some dogs will resort to behaviors they know usually get a reaction, even if it's a negative one. This might include suddenly grabbing a "forbidden" object (like a shoe), pawing at you relentlessly, or even performing a trick they know you like, all in an effort to divert your focus.

  5. Sudden House Soiling: A perfectly house-trained dog that suddenly starts urinating or defecating indoors, often on the belongings of the perceived rival (like a new partner's bed or a new baby's blanket), is not being "spiteful." This is a sign of extreme stress and an attempt to mark territory with their own scent to feel more secure.

  6. Withdrawal and Depression: While some dogs act out, others internalize their distress. A dog might become sullen, lethargic, lose interest in food or play, or hide when the rival is present. This is a passive but equally significant sign of emotional turmoil.

  7. Herding or Controlling Behavior: The dog may try to physically block you from moving toward another person or pet, or attempt to herd the "rival" away from you. This is common in herding breeds but can be seen in any dog trying to manage the social situation.

Unpacking the Triggers: Why Do Dogs Feel Jealous?

Understanding dog emotions requires looking at the world from their perspective. Jealous behaviors are triggered by perceived threats to their social standing and access to resources. The most important resource of all? You.

Common triggers include:

  • A New Social Rival: This is the most common category.

    • A New Human: A new baby, a romantic partner moving in, or even a long-term houseguest can disrupt the dog's established bond with you.

    • A New Pet: Bringing a new dog, cat, or other animal into the home is a primary trigger. The resident dog suddenly has to share everything: space, toys, and most importantly, your affection.

  • Divided Attention: In our modern world, the "rival" isn't always alive. Dogs can become intensely jealous of inanimate objects that monopolize our attention, such as laptops, mobile phones, or even books. The dog doesn't understand what these things are, only that when they are in your hands, you are no longer available.

  • Perceived Unfairness: Dogs have a surprisingly keen sense of fairness. If you are playing with or feeding another dog, your dog is watching closely. If they perceive the other dog is getting more or better resources (attention, treats, praise), it can trigger competitive and jealous behavior.

At its core, all of these triggers are variations of resource guarding. The resource being guarded is often the owner's affection and attention. This is a critical concept in pet behavior psychology. To move from understanding the problem to solving it, this guide provides actionable steps for addressing jealous behaviors in dogs.

A Humane Guide to Managing and Preventing Jealousy

Once you've identified the signs and triggers, you can begin to manage the behavior. The goal is not to punish the emotion—which is impossible and counterproductive—but to change the dog's emotional response and teach them more appropriate ways to behave.

Step 1: Rule Out Medical Issues Any sudden change in behavior warrants a trip to the veterinarian. Pain, discomfort, or an underlying medical condition can lower a dog's tolerance for stress and lead to irritability and aggression that can be mistaken for jealousy.

Step 2: Management and Environmental Control Management means changing the environment to prevent the problem behavior from being practiced.

  • Use baby gates, crates, or separate rooms to manage interactions, especially during the early stages of an introduction (like with a new pet or baby).

  • Feed pets in separate areas to prevent competition and conflict.

  • Remove high-value toys or chews when multiple pets are together to avoid resource guarding disputes.

Step 3: Behavior Modification and Training This is the most important step. You need to change your dog's association with the "rival" from a negative to a positive one.

  • Counter-Conditioning: The goal is to make the presence of the rival predict wonderful things for your dog. For example: every time you sit down to feed the new baby, have a partner or toss your dog a super high-value, long-lasting chew (like a puzzle toy filled with peanut butter). Every time you greet your new partner, shower your dog with praise and treats. The dog begins to think, "When my owner interacts with that person, I get amazing things! I want them to interact!"

  • Positive Reinforcement: Lavishly praise and reward your dog for any calm, non-jealous behavior in the presence of the trigger. If they are lying quietly on their bed while you're on your laptop, get up and give them a treat and gentle praise. You are rewarding the behavior you want to see more of.

  • Teach Incompatible Behaviors: Train your dog a rock-solid "Go to Place" or "Stay" command. When a situation arises that typically triggers jealousy (e.g., a guest arrives), you can proactively send your dog to their mat and reward them for staying there. They cannot be on their mat and jumping on the guest at the same time.

Step 4: Provide Structure, Routine, and Enrichment A dog's world is more stable and less stressful when it's predictable.

  • Consistent Routine: Maintain regular schedules for feeding, walking, and potty breaks. This predictability reduces anxiety.

  • One-on-One Time: Make sure your dog still gets dedicated, individual quality time with you every single day. This reassures them that their bond with you is secure.

  • Mental and Physical Exercise: A tired, mentally stimulated dog is a happy dog. Boredom and excess energy are major contributors to behavioral problems. Incorporate training sessions, puzzle toys, and vigorous exercise into their daily life.

When to Call a Professional

While many mild cases of jealousy can be managed with the steps above, you should seek professional help if:

  • Aggression is involved. Any growling, snapping, or biting is a serious issue that requires expert guidance to ensure everyone's safety.

  • The behavior is getting worse, not better.

  • You are feeling overwhelmed and unsure how to proceed.

Look for a qualified professional such as a board-certified Veterinary Behaviorist (DACVB), a Certified Applied Animal Behaviorist (CAAB), or a Certified Professional Dog Trainer (CPDT-KA) with proven experience in aggression and anxiety cases.

The American College of Veterinary Behaviorists is the official organization for board-certified experts in this field. You can find a qualified professional in your area through their directory: Find a Veterinary Behaviorist.
