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.

Coco and Lynettte
"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.”

Play with Your Pet from Anywhere in the World

PETCUBE: Petcube is a box with a laser pointer, speaker, and light that you can control from anywhere in the world via the Petcube smartphone app. You control the laser by moving your finger around your iPhone or Android phone’s screen. Anywhere your finger moves, your pet will follow, as long as she likes lasers. You can also take screenshots of the app and share them via Petcube’s social network. What’s more, you can make your Petcube open to the public, so you can let anyone play with your pet while you’re home or away. To be honest, letting strangers get a view of your home when you’re away (or home) sounds kind of strange, so maybe you’ll just want to stick with the lasers.

Pancreatitis

Pancreatitis is an inflammation of the pancreas caused by leakage of the digestive enzymes and causing the pancreas to "digest itself." Pancreatitis can be acute (sudden) or chronic (happening over a course of time.) Both acute and chronic forms are serious and can be life-threatening. Middle-aged dogs appear to be at increased risk of developing pancreatitis. Certain breeds are more prone to the disease, particularly Schnauzers and Yorkshire terriers. Pancreatitis is more common in overweight dogs. When pancreatitis occurs in an overweight dog it is more likely to cause serious illness.

Causes of Pancreatitis

Multiple factors can contribute to the development of pancreatitis including:

Certain medications: The medications most suspected of causing pancreatitis include azathioprine (Imuran Rx), potassium bromide (used for seizure control), l-asparaginase (a chemotherapeutic agent) and zinc used as a dietary supplement.

• Infections
• Metabolic disorders: Including hyperlipidemia (high amounts of lipid in the blood) and hypercalcemia (high amounts of calcium in the blood)
• Obesity
• Trauma and shock
• Scorpion stings

Nutrition also plays a major role. Dogs with high-fat diets, dogs that have recently eaten the trash, are fed table scraps, or 'steal' greasy people food have a higher incidence of the disease. In addition, dogs that have previously had pancreatitis or abdominal surgery appear to be more at risk.

Preventing Pancreatitis

Because fatty foods are a common cause of pancreatitis, it is good to limit the amount of fat in your dog?s diet. Be especially careful around the holidays as extra table scraps and fat trimmings in the garbage can trigger pancreatitis.

Symptoms of Pancreatitis

The signs can vary from mild gastrointestinal upset to collapse and death. However, most dogs have some signs of GI upset, such as:

• Vomiting
• Not eating
• Painful abdomen, hunched appearance
• Fever or below-normal body temperature
• Diarrhea
• Depression
• Dehydration which can be evaluated by noting sunken eyes, dry mouth, and increased skin turgor (skin tents when pinched)
• Difficulty in breathing
• Heart arrhythmias
• Inflammation of organs that surround the pancreas
• Infection and hemorrhages throughout the body

All or some of the signs may be present with pancreatitis, but are not specific for pancreatitis, and can be seen with many gastrointestinal diseases and conditions.

Diagnosing Pancreatitis

Pancreatitis can be diagnosed by looking at blood chemistries and biopsies. While biopsy is the gold standard, unless surgery is called for, these are not generally performed because of their invasive nature.

Treating Pancreatitis

The goal of treatment is to rest the pancreas, provide supportive care and control complications. If vomiting is severe, treatment usually consists of withholding all food, water, and oral medications for 24 hours to stop the stimulation of the pancreas. Depending on the dog's response, food can be reintroduced after a day. At that time, the dog should be fed small, bland, easily digestible meals that are high-carbohydrate, low-fat. Over a period of a week, meal size and quantity of food can be increased. The dog may need to stay on a special diet for life, or it may be possible to gradually reintroduce the former diet. High-fat diets or treats should be avoided. Since dehydration and electrolyte imbalances are common in dogs with acute pancreatitis and water intake is often restricted, fluid therapy is usually needed. Fluids are either given subcutaneously or intravenously.

Dogs that experience severe pain can be treated with pain relievers such as meperidine or butorphanol. Antibiotics are often administered prophylactically to protect against infection. If the pancreatitis was caused by a medication, the medication should be stopped. If it was caused by a toxin, infection, or other condition, the appropriate therapy for the underlying condition should be started. In rare instances where there are intestinal complications or the development of a pancreatic abscess, surgery may be necessary.

Caring for Dogs with Pancreatitis

Pancreatitis can be a very unpredictable disease. In most cases, if the pancreatitis was mild and the pet only had one episode, chances of recovery are good and avoiding high fat foods may be all that is necessary to prevent recurrence or complications. In other cases, what appears to be a mild case may progress, or may be treated successfully only to have recurrences, sometimes severe. Dogs with severe pancreatitis can recover, but may also develop fatal complications. The risk of developing fatal pancreatitis is increased in dogs that are overweight, or have diabetes mellitus, hyperadrenocorticism, hypothyroidism, gastrointestinal tract disease, and epilepsy. Dogs that suffer repeated bouts of pancreatitis may need to be fed low-fat diets to prevent recurrence.

Some dogs develop chronic pancreatitis, which can lead to diabetes mellitus and/or pancreatic insufficiency, also called maldigestion syndrome. In pancreatic insufficiency, the nutrients in food are passed out in the feces undigested. Dogs with this disease often has a ravenous appetite, diarrhea, and weight loss. Even though he is eating, he could literally starve to death. Treatment for pancreatic insufficiency is lifelong and expensive, but is possible. The dog?s digestive enzymes are replaced through a product processed from pancreases of hogs and cattle which contain large quantities of the digestive enzymes. A change in diet with added nutritional supplements may also be necessary.

People Foods to Avoid Feeding Your Pets

Chocolate, Macadamia nuts, avocados…these foods may sound delicious to you, but they’re actually quite dangerous for our animal companions. Our nutrition experts have put together a handy list of the top toxic people foods to avoid feeding your pet. As always, if you suspect your pet has eaten any of the following foods, please note the amount ingested and contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.

Chocolate, Coffee, Caffeine
These products all contain substances called methylxanthines, which are found in cacao seeds, the fruit of the plant used to make coffee and in the nuts of an extract used in some sodas. When ingested by pets, methylxanthines can cause vomiting and diarrhea, panting, excessive thirst and urination, hyperactivity, abnormal heart rhythm, tremors, seizures and even death. Note that darker chocolate is more dangerous than milk chocolate. White chocolate has the lowest level of methylxanthines, while baking chocolate contains the highest.

Alcohol
Alcoholic beverages and food products containing alcohol can cause vomiting, diarrhea, decreased coordination, central nervous system depression, difficulty breathing, tremors, abnormal blood acidity, coma and even death.

 Avocado The leaves, fruit, seeds and bark of avocados contain Persin, which can cause vomiting and diarrhea in dogs. Birds and rodents are especially sensitive to avocado poisoning, and can develop congestion, difficulty breathing and fluid accumulation around the heart. Some ingestions may even be fatal.

Macadamia Nuts
Macadamia nuts are commonly used in many cookies and candies. However, they can cause problems for your canine companion. These nuts have caused weakness, depression, vomiting, tremors and hyperthermia in dogs. Signs usually appear within 12 hours of ingestion and last approximately 12 to 48 hours.

Grapes & Raisins Although the toxic substance within grapes and raisins is unknown, these fruits can cause kidney failure. In pets who already have certain health problems, signs may be more dramatic. Yeast Dough Yeast dough can rise and cause gas to accumulate in your pet’s digestive system. This can be painful and can cause the stomach or intestines to rupture. Because the risk diminishes after the dough is cooked and the yeast has fully risen, pets can have small bits of bread as treats. However, these treats should not constitute more than 5 percent to 10 percent of your pet’s daily caloric intake.

Raw/Undercooked Meat, Eggs and Bones
Raw meat and raw eggs can contain bacteria such as Salmonella and E. coli that can be harmful to pets. In addition, raw eggs contain an enzyme called avidin that decreases the absorption of biotin (a B vitamin), which can lead to skin and coat problems. Feeding your pet raw bones may seem like a natural and healthy option that might occur if your pet lived in the wild. However, this can be very dangerous for a domestic pet, who might choke on bones, or sustain a grave injury should the bone splinter and become lodged in or puncture your pet’s digestive tract.

 Xylitol
Xylitol is used as a sweetener in many products, including gum, candy, baked goods and toothpaste. It can cause insulin release in most species, which can lead to liver failure. The increase in insulin leads to hypoglycemia (lowered sugar levels). Initial signs of toxicosis include vomiting, lethargy and loss of coordination. Signs can progress to recumbancy and seizures. Elevated liver enzymes and liver failure can be seen within a few days.

Onions, Garlic, Chives
These vegetables and herbs can cause gastrointestinal irritation and could lead to red blood cell damage. Although cats are more susceptible, dogs are also at risk if a large enough amount is consumed. Toxicity is normally diagnosed through history, clinical signs and microscopic confirmation of Heinz bodies. An occasional low dose, such as what might be found in pet foods or treats, likely will not cause a problem, but we recommend that you do NOT give your pets large quantities of these foods.

Milk
Because pets do not possess significant amounts of lactase (the enzyme that breaks down lactose in milk), milk and other milk-based products cause them diarrhea or other digestive upset. Salt Large amounts of salt can produce excessive thirst and urination, or even sodium ion poisoning in pets. Signs that your pet may have eaten too many salty foods include vomiting, diarrhea, depression, tremors, elevated body temperature, seizures and even death. In other words, keep those salty chips to yourself!

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.

Labor Day Safety Tips for Pets

1. Do not apply any sunscreen or insect repellent product to your pet that is not labeled specifically for use on animals.

2. Always assign a dog guardian. No matter where you're celebrating, be sure to assign a friend or member of the family to keep an eye on your pooch-especially if you're not in a fenced-in yard or other secure area.

3. Made in the shade. Pets can get dehydrated quickly, so give them plenty of fresh, clean water, and make sure they have a shady place to escape the sun.

4. Always keep matches and lighter fluid out of paws' reach. Certain types of matches contain chlorates, which could potentially damage blood cells and result in difficulty breathing-or even kidney disease in severe cases.

5. Keep your pet on his normal diet. Any change, even for one meal, can give your pet severe indigestion and diarrhea.

6. Keep citronella candles, insect coils and oil products out of reach. Ingesting any of these items can produce stomach irritation and possibly even central nervous system depression in your pets, and if inhaled, the oils could cause aspiration pneumonia.

7. Never leave your dog alone in the car. Traveling with your dog means occasionally you'll make stops in places where he's not permitted. Be sure to rotate dog walking duties between family members, and never leave your animals alone in a parked vehicle.

8. Make a safe splash. Don't leave pets unsupervised around a pool-not all dogs are good swimmers.

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.
