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 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.”

Plant-based dog foods are better for the environment than red meat options

Plant-based diets for pets had the lowest impact across all measures of environmental impact. This included the land needed to produce them, greenhouse gas emissions, the polluting effects of production on soil and water reservoirs, and freshwater withdrawal.

Published

A study, led by experts at the University of Nottingham, has found that the production of meat-based pet foods has a much greater impact on the environment in comparison to plant-based alternatives.

The study, led by Rebecca Brociek from the School of Veterinary Medicine and Science, and published in Frontiers in Nutrition – Nutrition and Sustainable Diets, showed that plant-based diets for pets had the lowest impact across all measures of environmental impact. This included the land needed to produce them, greenhouse gas emissions, the polluting effects of production on soil and water reservoirs, and freshwater withdrawal.

Pet food production contributes substantially to global environmental issues, driven largely by animal-derived ingredients.

In this study, experts quantified the environmental impact of 31 commercially available dry dog foods purchased in the UK, categorised as plant-based, red-meat based and veterinary-renal diets.

The environmental metrics were estimated using life cycle assessment datasets and adjusted for ingredient makeup, energy density and differences in moisture content, which were mostly taken from the dog food packaging.

The results showed that plant-based diets had the lowest impact across all measures of environmental impact. Poultry-based and veterinary diets were intermediate, while beef and lamb-based foods had substantially higher impact compared to all other foods.

For example, over nine years of adult life, a 20kg dog fed a beef-based diet was estimated to require 57 football fields worth of land to grow their food (versus 1.4 fields for plant-based).

This latest study comes after a previous study where the team showed that plant-based pet food sold in the UK provided similar nutrition to meat-based food.

“Our findings show that there is a much greater environmental impact when producing meat-based pet food.

 “We have already show in our previous work that plant-based diets at the point of purchase are roughly equivalent to others. This next paper is a case study of 31 supermarket-available dog foods, giving dog owners who factor sustainability into their purchases, guidance on how to also reduce their environmental pawprint,” says Rebecca, the lead author on the study.

Back-to-school season can be ruff on pets

The “back-to-school blues” can affect dogs and cats alike, but there are things you can do to help ease their transition.

Published

After a summer of lazy mornings, long walks, and extra attention from the kids at home, the sudden shift to hectic mornings, rushed drop-offs, and quiet households during the day can be confusing and stressful for our furry companions. The “back-to-school blues” can affect dogs and cats alike, but there are things you can do to help ease their transition.

Pets Feel the Change

Dogs and cats thrive on routine and companionship. When their human family suddenly disappears during the day, they may experience boredom and separation anxiety, or changes in appetite and behavior. 

Easing the Transition

1. Gradual Changes

If your kids haven’t started school yet, start adjusting your pet’s routine one to two weeks before school starts. Slowly shift feeding, walking, and play times to match the upcoming schedule. Making incremental changes will make the adjustment feel less abrupt for our pets.

2. Spend Quality Time in the Morning and Evenings

Spend a few minutes each morning playing with or walking your dog. This gives pets a positive start to the day and reinforces their bond with the family. Exercising your dog in the morning also helps them burn off nervous energy so they can nap during the day. After school and work, be sure to give pets plenty of love, attention, and exercise. A walk, cuddle session, or playtime helps them feel valued and part of the family again.

3. Keep Them Busy and Distracted

Turn on the TV or radio to help make the house less quiet. Give your pet a puzzle toy and a new chew toy to keep them busy when they are home alone. Besides making a variety of chews to match your dog’s needs and preferences, Nylabone makes innovative treat toys designed to keep your dog entertained longer. Their Stuffable Cone Dog Treat Toy and Fillable Peanut Dog Chew Toy allow you to put treats in the toy so your dog can stay preoccupied for hours trying to get the treats out. And as a bonus, in celebration of their 70th birthday, Nylabone is donating a chew toy to Best Friends Animal Society for every purchased Nylabone. In addition to helping your dog stay busy, you’re helping enrich a shelter pet’s life. For more information or to upload your receipt go to: NylaboneCares.com

4. Give Them a Cozy New Bed

Buy your dog or a cat a new bed to encourage naps and relaxation while everyone is away. P.L.A.Y has a large selection of cozy, comfortable, and easy to maintain beds. Their California Dreaming Memory Foam Bed has plush bolster sides and a memory foam center cushion to provide extra comfort and support for your pup.

5. Watch for Signs of Stress

Excessive barking, chewing, bathroom accidents, or changes in behavior might be signs of separation anxiety. Consider trying calming products to help decrease your pet’s anxiety. There are all kinds of calming products available nowadays designed to decrease stress and anxiety in dogs and cats. Also consider doggy day care or setting up afternoon dog walks to get some of your pet’s energy out and break up their day. And remember if none of this helps, be sure to contact your veterinarian for help.

Pets Are Part of the Family Too

Back-to-school season is a time of growth and change, not just for children but for the whole household. With a little empathy and effort, your pets can adjust to the new routine and continue to thrive. There is no better way to end the school day, then coming home and being greeted by your four-legged friend waiting at the door.
