Scents and Sensitivity: Dogs Know When We’re Happy or Angry

Science is proving what pet owners have long believed: Dogs understand what we're feeling. Specifically, dogs can recognize the difference between a happy and an angry human face, a study published Thursday in Current Biology suggests.

It's the first research to show definitively that dogs are sensitive to our facial expressions, says coauthor Ludwig Huber, head of comparative cognition at Messerli Research Institute at the University of Veterinary Medicine, Vienna.

In the Austrian study, 20 pet dogs of various breeds and sizes were taught to play a computer game through a series of exercises. In the first, the dogs were shown two touch screens, one with a circle and one with a square. Through trial and error, they learned that a treat would appear if they chose the right geometrical figure.

Eleven of the 20 dogs were able to catch on to rules of the game and make it to the next phase, where they were shown photos of faces. Half the dogs were rewarded for picking a happy expression and half for choosing an angry expression. The interesting catch: the dogs were shown only the upper half or the lower half of a face.

It was easier to teach the dogs to choose a happy expression than an angry one, suggesting the dogs do indeed understand the meaning behind the expression, Huber says.

As a test, the dogs were then were presented with:

the same half of the faces they saw during the training, but from different people
the other half of the faces used in training
the other half of new faces
the left half of the faces used in training
In the vast majority of cases the dogs chose the right answer 70 to 100 percent of the time.

Dogs who had been trained to recognize an expression of anger or happiness on the upper part of a face could identify the same expression when shown only the lower part, and vice versa, Huber says, adding “the only possible explanation is that they recall from memory of everyday life how a whole human face looks when happy or angry.”

Dog owners know their pets not only recognize emotions but also feel empathy.

Delilah, a 3-year-old Chihuahua, always seems to know when her owner Eva Shure is having a bad day.

Delilah knows when her owner is having a bad day.
Making eye contact and cocking her head to the right, the little dog will stare at Shure's face as if trying to assess her feelings. “It’s weird, I can see her thinking and processing,” says Shure, a 35-year-old New York City business owner. “I’ll say, yeah, it’s not a great day and she’ll come up and sit next to me.”

Beverly Levreault, 57, says her 6-year-old Australian Cattle Dog mix is always tuned in to her moods. “If I’m not feeling well, like when I have the flu, Lacey is definitely lower key and will not leave my side, ” says Levreault, a graphic designer from Williamstown, New York. “If I take her for a walk, she’s not as rambunctious as she usually is.”

Lynette Whiteman says she’s not sure that her 5-year-old Yorkie-Maltese cross is using facial expressions to gauge how she feels. “But she definitely reads my emotions,” says the 58-year-old from Toms River, New Jersey. “I run a therapy dog program and the dogs are just amazing. They go into a room and immediately pick out the person who needs help.”

Behavioral experts say the new findings, while important, wouldn’t surprise anyone with an intimate knowledge of dogs.

"This new work continues to build the case for just how sensitive dogs are to our subtle behaviors,” says Dr. Brian Hare, chief scientific officer at Dognition and an associate professor of evolutionary anthropology at Duke University. “This is the strongest evidence yet that dogs are even reading our facial expressions.”

That sensitivity may be the result of generations of selective breeding for a true partner, says Dr. Carlo Siracusa, director of the behavior service at the University of Pennsylvania School of Veterinary Medicine. “We have selected animals that are able to perceive our emotions and communicate with us at a level that no other animal can,” Siracusa says.

Dogs may not talk, but they are very good communicators, says Dr. Nicholas Dodman, a professor in the department of clinical sciences at the Cummings School of Veterinary Medicine at Tufts University and director of the animal behavior clinic at Cummings.

“Just as we are masters of the spoken word, dogs are experts at reading body language,” Dodman says.

“It’s almost impossible to hide your feelings from a dog.”

Turns out, reading facial expressions isn’t the only thing dogs have in common with us.

They can be bitten by the computer gaming bug. “They can really become freaks for it,” Huber says with a chuckle. “They don’t want to stop playing. It’s incredible. They’ll play till they are exhausted and fall asleep.”

Pet Decoration Safety

‘Tis the season……..of apple pie treats, pine needle scents, glass ornaments twinkling on the tree….and of trees crashing to the ground in your living room while kitty scales the branches!  If you live with cats, hang heirloom glass ornaments up high, away from kitty paws, and anchor your tree with guy wires.  Avoid gift ribbons, tinsel, and metallic garland.  Cats like to eat them, but they may not exit your cat without the help of your veterinarian!  Wrap electrical cords with plastic tubing to preventing high voltage snacking.  And finally, forgo the chemicals that keep your tree fresh longer if there’s any chance your cat could drink it.  Many of these chemicals are toxic to cats!   

THANKSGIVING SAFETY TIPS FOR PETS

Thanksgiving is just around the corner, and it’s a great occasion to have your family join you in the kitchen for a fun day of food prep. When the enticing aromas of food start wafting through your house, it’s likely that your pets will want to get in on the action. However, the hectic environment in the kitchen on this food-filled holiday poses some potential health risks for your pets. Remember these safety tips as you whip up the perfect batch of mashed potatoes and gravy:

Let’s talk turkey: If you decide to give your pet a nibble of your Thanksgiving turkey, make sure it’s boneless and well-cooked—no raw or undercooked turkey, which may contain salmonella bacteria.

Sage advice: While sage can be a delicious addition to your Thanksgiving stuffing, it and many other herbs contain essential oils and resins that can cause gastrointestinal upset and central nervous system depression in pets. Cats are especially sensitive.

 Doughy dangers: When an animal ingests raw bread dough, his body heat causes the dough to rise in his stomach. Ouch! This may cause vomiting, severe abdominal pain and bloating, which could become a life-threatening emergency.

Cake batters made with raw eggs are also dangerous to pets. Portion control, please: While it’s ok to share a bit of well-cooked turkey with your furry friend, it’s best to stick to your pet’s regular diet during the holidays. Allowing your pets to over indulge could cause stomach upset, diarrhea or pancreatitis.

Why dogs bark and growl

Does your dog growl or bark when a stranger approaches your house or when something goes bump in the night? If so, you’re not alone. Most dogs will vocalize when they are exposed to new or different situations, including strange people or animals entering their territory; being separated from their pack, mother or even your family members; or new or alarming sounds. Dogs may also bark or growl when they see prey, such as squirrels, and they may bark for attention, food or if they are anxious.

Dogs often growl when they are fearful or trying to assert themselves in a situation. If the dog’s fear or assertiveness is alleviated by growling or barking, the dog will learn that his behavior is acceptable and the behavior may become more frequent or severe. Some medical problems may cause growling or barking and older pets experiencing senile changes may have barking problems. Intense and continuous barking may be considered compulsive. Check with your veterinarian to evaluate your pet’s barking or growling problem. Behavior training and drug therapy may be helpful in reducing barking for pets with medical, geriatric and compulsive disorders. Socializing your puppy can help Acclimate your puppy to a variety of different people, environments, situations and noises to help lessen anxiety as your puppy grows.

Make sure your puppy spends time alone so that he doesn’t develop separation anxiety while you are away from him. Proper training is essential to preventing behavior problems, such as growling and barking. Ask you veterinarian for more information about puppy training. Correcting a barking or growling problem Correcting a barking or growling problem first requires that you have effective management of your dog. Once you have achieved this, you can begin to train your dog to lessen his barking or growling behavior by using rewards for quiet behavior. The reward should be something that the dog really likes such as a favorite treat, tummy rubs, or a favorite toy.

Punishment is generally ineffective in correcting barking problems. Too much punishment may even exacerbate the behavior and cause the dog to be fearful or aggressive. Begin your training with situations that you can easily control (such as a family member making a noise that causes the dog to bark) before moving on to difficult situations (such as a strange animal in your yard). When your dog barks at the stimuli (for instance, a doorbell ring), immediately interrupt the barking. When the dog is quiet offer the dog a reward for their behavior. Without the reward there is no incentive to remain quiet.Reward your dog when, at your request, he has stopped barking. Only reward the dog when he is quiet and gradually increase the amount of time that the dog needs to be quiet for him to receive a reward. As the barking or growling problem decreases, make sure to direct your dog to more appropriate behavior, such as play, and the problem should lessen over time. Don't forget to discuss training options with your veterinarian to find the one that will work best for your pet.

Three Essential Summer Tips For Dogs

It's summertime and the living is easy, but summer fun also brings some inherent dangers to be aware of. Dog owners need to take extra responsibility to make sure their pup is safe when temperatures heat up and outdoor activity beckons. 

Everyone knows you should never leave a dog in a hot car, but it's also important to be aware that your pup can get heatstroke while they're outside.

Heat Hazards 

If your dog is outside on a hot day, make sure he has a shady spot to rest in. Doghouses are not good shelter during the summer as they can trap heat. You may want to fill a child's wading pool with fresh water for your dog to cool off in. Never leave your dog in a closed vehicle on a hot day. The temperature inside a car can rise to over 100 degrees in a matter of minutes. Always provide plenty of cool, fresh water. Avoid strenuous exercise on extremely hot days. Take walks in the early mornings or evenings, when the sun's heat is less intense. Try to avoid prolonged exposure to hot asphalt or sand, which can burn your dog's paws. Dogs that are brachycephalic (short-faced), such as Bulldogs, Boxers, Japanese Chins, and Pekingese, have an especially hard time in the heat because they do not pant as efficiently as longer-faced dogs. Keep your brachycephalic dog inside with air-conditioning. Lisa and I just got back from visiting our friends in Wilmington, N.C. where we were lucky enough to spend a few glorious days boating and going to the beach. You would be amazed at how many boating dogs there were, it seemed everywhere I looked there was a dog on a boat. While on the beach an endless number of dogs were running, playing, and splashing around. So, next I thought it would be a good idea to go over some safety tips for those planning on taking Fido to the beach. 

Beach Tips 

Make sure your dog has a shady spot to rest in and plenty of fresh water. Dogs, especially those with short hair, white fur, and pink skin, can sunburn. Limit your dog's exposure during the day and apply sunblock to his ears and nose 30 minutes before going outside. Check with a lifeguard for daily water conditions. Dogs are easy targets for sea lice and jellyfish. Running on the sand is strenuous exercise. A dog that is out of shape can easily pull a tendon or ligament, so keep a check on your dog's activity. Do not let your dog drink seawater; the salt will make him sick. Salt and other minerals in ocean water can damage your dog's coat, so rinse him off at the end of the day. Not all beaches permit dogs; check local ordinances before heading out. Since we're talking about the beach this naturally leads us to our final tip, water safety. Remember, while you may enjoy swimming, your dog may not. For those that do, it's important they are not allowed to swim without supervision. It sounds obvious, but every year dogs drown due to owner negligence. 

Water Safety 

Most dogs enjoy swimming, but some cannot swim, and others may hate the water. Be conscious of your dog's preferences and skills before trying to make him swim. If you're swimming for the first time with your dog, start in shallow water and coax him in by calling his name. Encourage him with toys or treats. Or, let him follow another experienced dog he is friendly with. Never throw your dog into the water. If your dog begins to paddle with his front legs, lift his hind legs and help him float. He should quickly catch on and keep his back end up. Don't let your dog overdo it; swimming is very hard work and he may tire quickly. If swimming at the ocean, be careful of strong tides. If you have your own pool, make sure your dog knows where the stairs or ladder are located. Be sure that pool covers are firmly in place; dogs have been known to slip in under openings in the covers and drown. Never leave your dog unattended in water. 

Summer is the time when ticks and fleas are out in full force, it's important that your pets be treated. If you're not sure about what to use contact your veterinarian for advice. Dogs can also have more allergies in the summer so you need to be aware of the signs so you can seek proper treatment. Lastly, with more outdoor activities comes more accidents. Knowing how to care for your dog in case of an emergency can potentially save his or her life.

Welcome Dr. Kathleen O'Hara

I grew up as an Army brat, moving around the country, stopping off at state and national parks along the way.  My mother fostered my interest in nature and animals early on – from looking at pond water under the microscope to naming the wildlife in our backyard.  We grew up with a menagerie of household pets and summers spent at horseback riding camps.

After settling in Virginia, I attended Virginia Tech, where I double majored in biology and psychology, with special interests in football and animal behavior.  GO HOKIES!  Next I headed south to Duke University, where I earned a Master’s in Immunology before heading to veterinary school at Cornell University.  During my time at Cornell I pursued special interests in public health, infectious disease and critical care medicine.  Following graduation, I completed a rotating internship at Petcare Veterinary Hospital in Santa Rosa before coming to Arguello Pet Hospital.

Beyond work, I love a chance to get outside and enjoy the California sunshine with family and friends. I enjoy music, hiking, running, playing soccer, salsa dancing, or finding a new book at the library.  My two cats, Tyler and Sasha, have been my constant companions throughout all my moves and adventures; I am fortunate to have them to come home to each day.

Car Sickness In Pets

Does your dog throw up in the car when you go for rides? He may be experiencing typical motion sickness, just like some people do. Motion sickness usually begins very shortly after starting the car ride. The dog will begin to drool and then vomit. It’s not serious, but certainly not something that we like to clean up! To solve the problem, first try acclimating the dog to car rides. Do this by simply putting him in the car for a few minutes each day without going anywhere. Then try just going down the driveway and back, and the next day going around the block. Gradually build up the distance and time the dog rides in the car. 

 Sometimes this will help to decrease the dog’s anxiety over riding in the car and may help to decrease vomiting. If that doesn’t work, there are some over-the-counter medications you can try. The medication will need to be given about an hour before the car ride. Ask your veterinarian for a recommendation as to what drug to try and the dosage for your pet.

(Never give any medications to your pet without your veterinarian’s advice!) These drugs are safe, with drowsiness usually the only major side effect. But since your dog isn’t driving the car, that shouldn’t be a problem! If over-the-counter drugs don’t work, your veterinarian may be able to suggest another method for curing the car sickness.
