Dogs act jealously even when they don’t see their rival
Dogs appear to be one of the few species that might display jealous behaviors in ways similar to a human child showing jealousy when their mother gives affection to another child. In humans, jealousy is closely linked with self-awareness, which is one reason animal-cognition researchers are so interested in studying jealousy and other secondary emotions in animals.
Past surveys have shown that more than 80% of dog owners report observing jealous behaviors from their dogs–vocalizations, agitated behavior, pulling on a leash–when they give attention to other dogs. New research published in the journal Psychological Science supports these observations and finds that dogs also exhibit jealous behaviors when they merely imagine that their owner is interacting with a potential rival, in this case, a highly realistic artificial dog.
“Research has supported what many dog owners firmly believe–dogs exhibit jealous behavior when their human companion interacts with a potential rival,” said Amalia Bastos with the University of Auckland and lead author on the paper. “We wanted to study this behavior more fully to determine if dogs could, like humans, mentally represent a situation that evoked jealousy.”
Dogs appear to be one of the few species that might display jealous behaviors in ways similar to a human child showing jealousy when their mother gives affection to another child. In humans, jealousy is closely linked with self-awareness, which is one reason animal-cognition researchers are so interested in studying jealousy and other secondary emotions in animals.
To test how and when dogs display jealous behavior, the researchers presented 18 dogs with situations where they could imagine a social interaction between their human companion and either a realistic fake dog or a fleece cylinder. The fake dog served as a potential rival for attention while the cylinder served as a control.
In the experiment, the dogs observed the fake-dog rival positioned next to their owner. A barrier was then placed between the dog and the potential rival obscuring them from view. Despite blocking the line of sight, the dogs forcefully attempted to reach their owners when they appeared to stroke the rival fake dog behind the barrier. In a repeat experiment using a fleece cylinder rather than a fake dog, the dogs pulled on the lead with far less force.
Through their study, Bastos and her colleagues found that dogs showed three human-like signatures of jealous behavior. Jealous behavior emerged only when their owner interacted with a perceived social rival and not an inanimate object; occurred as a consequence of that interaction and not due to a potential rival’s mere presence; and emerged even for an out-of-sight interaction between their owner and a social rival.
“These results support claims that dogs display jealous behavior. They also provide the first evidence that dogs can mentally represent jealousy-inducing social interactions,” said Bastos. “Previous studies confounded jealous behavior with play, interest, or aggression, because they never tested the dogs’ reactions to the owner and the social rival being present in the same room but not interacting.”
“There is still plenty of work to do to establish the extent of the similarities between the minds of humans and other animals, especially in terms of understanding the nature of nonhuman animals’ emotional experiences,” said Bastos. “It is too early to say whether dogs experience jealousy as we do, but it is now clear that they react to jealousy-inducing situations, even if these occur out-of-sight.”

Tips for smooth travel with pets
The American Veterinary Medical Association (AVMA) recommends planning ahead for calm, comfortable trips for you and your pets.
The American Veterinary Medical Association (AVMA) recommends planning ahead for calm, comfortable trips for you and your pets.
According to AVMA President, Dr. Michael Q. Bailey, visit your veterinarian to make sure your pet is current on all vaccinations and you have all the paperwork and medications necessary for your journey.
“Summer travel is exciting, but it comes with real responsibilities for pet owners that are easy to overlook,” said Dr. Bailey. “Before you head out, talk to your veterinarian. Whether your pet is coming along or staying behind, a little preparation can make all the difference.”
Bailey’s advice begins with considering whether travel is right for your pet, as some dogs, cats, and other animals may be uncomfortable with travel due to illness, injury or temperament. Consider a pet sitter or boarding your pet if there’s a chance they may not be comfortable traveling. If you’ve decided to bring your pet along, here are the AVMA’s top pet travel tips:
The Basics
- Ensure your pet has up-to-date ID tags and a microchip.
- Introduce your pet to their carrier and travel harness before the trip. Placing a familiar toy or blanket in the carrier can help your pet feel more comfortable.
- Check your airline’s or carrier’s pet travel policies before you depart.
What to Bring
- Proof of vaccination, pet ID info, and a recent photograph.
- Leash, water dish, waste bags, blankets, treats, car carrier, toys and a pet first aid kit.
- Enough food to last the entire trip.
- Your pet’s medications and your veterinarian’s phone number.
For Added Comfort and Safety
- Research a list of veterinarians in your destination in case of emergency.
- Offer your pet water frequently, and take time for exercise and bathroom breaks.
- Never, ever leave your pet alone in a parked car.
- If you plan to stay in a hotel, motel, park, or campground, ask if there are any breed or size restrictions; if any paperwork is required; and what features they may offer to meet your pet’s needs.

Living with cats does not worsen asthma in children, suggests study
Children living with a cat had similar asthma severity, exacerbation, asthma control, and lung function to children living without cats in the short term.
Asthma is the most common chronic disease and one of the main causes of hospitalization among children. The Global Asthma Network has estimated that its global prevalence is 9.1% for children and 11.0% for adolescents, but this percentage varies greatly between countries, regions, and environments. Worldwide, the highest prevalence of pediatric asthma (above 20%) occurs in the British Isles and in parts of Oceania and the Middle East. Known risk factors for developing asthma include exposure to air pollution and smoking, childhood viral infections, obesity, and pre-existing allergies like eczema or hay fever.
Patients anecdotally self-report that exposure to animal dander appears to trigger asthma attacks. However, clinical and epidemiological data on this is so far contradictory, coming mostly from small studies on subgroups that aren’t necessarily representative of the wider population. Now, researchers have demonstrated in Frontiers in Allergy that sharing a home with cats may not worsen the outcomes of children with asthma and allergies.
“Here we show in a… cohort of children in Sweden with asthma and allergies, that children living with a cat had similar asthma severity, exacerbation, asthma control, and lung function to children living without cats in the short term,” said corresponding author Dr Resthie R Putri, a postdoctoral fellow at Karolinska Institutet in Stockholm.
“We also did not see any differences in asthma outcomes related to the number of cats, the cat’s sex, or the cat’s age.”
Large pediatric sample
In 2023, Putri and colleagues began a study on a cohort of 30,277 children – between four and 17 years old at the time – born between 2006 and 2020 and diagnosed with asthma or an airway allergy. They followed these over 24 months until 2024 to track asthma outcomes, drawing records on diagnoses, emergency visits, prescribed medications, and asthma control test and spirometry tests from linked data in the Swedish National Patient Register, Prescribed Drug Register, and National Airway Register.
In Sweden, registration in the National Cat Register has been mandatory since 2023 for all pet cats born after 2008. For each child, the authors noted whether the parental household had at least one cat in 2023, as was true for 9.4% of the children.
Cats don’t worsen asthma in kids
The results showed that there was no significant association between exposure to pet cats and asthma outcomes. For example, moderate-to-severe asthma – based on prescribed asthma medications – occurred in 9.6% of the cat-exposed children and 10.1% of the non-exposed children. Asthma ‘exacerbation’ (also known as an attack or flare-up) occurred in 3.3% of the cat-exposed children and 3.5% of the non-exposed children.
Among a subset of 1,428 children for whom asthma control and lung spirometry data were available, 97 (6.8%) lived with cats. There were no significant differences between the two groups in two common measures of lung function.
“One possible explanation is that cat allergen exposure is very common, even outside the home. Children who do not have cats at home may still be exposed in shared environments such as schools or public transportation, which could explain why we didn’t see a difference,” said Putri.
“While these large-scale findings provide valuable insight, we lacked data on which allergens the children were sensitized to, and because the National Cat Register is relatively new, some children living with cats may have been misclassified as unexposed,” she cautioned.

Tips to keep pets safe and happy no matter the season
The American Veterinary Medical Association (AVMA) is reminding everyone to keep pets safe no matter the season, and to think twice before gifting a pet as a surprise.
Special occasions can be a magical time, but they can also present hidden pet hazards and difficult decisions for pet owners and gift-givers. The American Veterinary Medical Association (AVMA) is reminding everyone to keep pets safe no matter the season, and to think twice before gifting a pet as a surprise.
“Holiday celebrations often mean delicious foods, beautiful decorations, and friends and family, which can be wonderful for us but may pose unexpected risks to our pets,” says Dr. Michael Q. Bailey, president of the AVMA. “The best gift you can give your pet… is the gift of good health and safety, which means keeping seasonal hazards out of reach, providing a quiet space away from the hustle and bustle, and ensuring emergency plans are in place in case the unexpected happens.”
Common hazards for pets include chocolate, baked goods (especially those containing the sugar substitute xylitol), table scraps, and certain seasonal plants like lilies, holly, and mistletoe. Tinsel, candles, electrical cords, and trees can also lead to injuries or worse if pets decide to investigate too closely.
Thinking about gifting a pet? Think again.
While the idea of a new puppy or kitten under the tree may warm hearts, the AVMA cautions against surprising someone with a live animal. Pets are long-term commitments that require a significant amount of time, planning, financial resources, and emotional investment.
“Bringing a pet into someone’s life is a decision that should never be made impulsively, and never without the foreknowledge of the recipient,” says Dr. Bailey. “Pets can bring immense joy, but they also require daily care, training, veterinary visits, and love for many years. A better option might be wrapping up a collar, toy, or gift certificate, and involving the future pet owner in choosing their new companion when the time is right.”
Instead of gifting a live animal, the AVMA recommends more thoughtful alternatives, such as:
- A leash or collar with a note promising a trip to a shelter or reputable breeder
- Books on pet care or breed characteristics
- A donation in the recipient’s name to a local animal shelter
Healthy gift ideas for pets
If your own pets are on your holiday list, the AVMA suggests practical and healthy gifts, such as:
- A veterinary wellness exam
- Toys that encourage exercise and mental stimulation
- Nutritional treats made for pets
- Updated parasite prevention
- Pet insurance
- A microchip (or updating existing chip info)
“Even something as simple as a microchip can be a lifesaving gift if your pet ever becomes lost,” adds Dr. Bailey. “It’s a gift that lasts a lifetime, and helps to ensure that you will be reunited if you and your pets become separated.”
