Scientists have known for decades that some mammals, bees, birds, reptiles, amphibians and fish are capable of seeing ultraviolet light. A new study published earlier this year has added dogs and cats to the list of animals that can see UV light. This means that dogs and cats can see things we can’t, which might explain why your pet stares at something that’s invisible to you.
On the color spectrum, the visible light we can see includes red, orange, yellow, green, blue and violet. Ultraviolet light sits above violet, and is invisible to us because the lenses in our eyes block out ultraviolet wavelengths that can be harmful. UV light has shorter wavelengths than the visible light we can see.
Before this study came out, scientists believed dogs and cats also had protective lenses on their eyes that would filter out UV light, but they don’t. They have UV transparent lenses which allow the light to enter into the retina where it’s converted into nerve signals, sent to the brain and processed by the visual system. In addition to dogs and cats, rodents, hedgehogs, ferrets and okapis (an African animal related to giraffes) were all added to the list of animals with transparent lens. And the amount of UV light they can detect is significant.
Ivan Pavlov, a Russian scientist, won the Nobel Prize in Physiology in 1904 for his work on the digestive system of mammals. He is famous for his revelation in classical conditioning. Pavlov discovered by accident that the dogs in his lab had learned to associate food with his lab assistants. They would salivate when any of the assistants entered the room whether they had food or not. It was a response to a stimuli and something the dogs learned on their own. Classical conditioning was the first step in beginning to understand how dogs think.
From the beginning of the 1900s up to the 1960s, scientists focused on dog behavior, but they lost interest and didn’t resume studying canines until the beginning of the 21st century. For the last 14 years, scientists have found a renewed interest in canine research to better understand a dog’s body language – including subtle signs they use, how they think, how they learn, the emotions they feel, how they view their world, and what they like. As we learn more about why dogs behave in certain ways, we have a better understanding of the canine mind and what dogs think about.
Of course, the answer to the question of what dogs think about is as complex as it is in determining what humans think about. We don’t have the ability to get inside the mind of another person to understand precisely what’s going on in their mind, nor can you really understand what your dog is thinking about when he’s staring at you. I know from personal experience how good some dogs are at problem solving, especially if they are trying to figure out a way to escape from their enclosure or steal food behind your back.
“Object permanence” is a term created by Swiss psychologist Jean Piaget. It’s the ability to understand that an object continues to exist even if it disappears. It may be gone from view, but we know it still exits even though we can’t see, touch, smell or hear it. This concept is an important development of awareness that human babies learn at around 18-24 months.
Researchers have discovered that dogs also understand the concept of object permanence, and it occurs earlier in canines than it does in humans. Puppies can understand the concept as early as 5 weeks. It’s easiest to see when you watch how dogs react to magic tricks.
Object permanence is not an ability that humans or dogs are born with. It’s a learned perception of awareness that comes from processing the existence of a stimulus while it is present. One summer a chipmunk set up an underground home inside my dog pen. I wasn’t aware of it, but noticed that my dog, Dozer, kept nosing around in one corner of the pen. It was obvious a smell had his interest, but he acted more curious than anything else. That is, until he caught sight of the chipmunk scurrying into his hole. Once he saw the critter disappear into the hole, his terrier heritage kicked in. Even though he couldn’t see the chipmunk, he knew it was in that hole. I’m sure it was Dozer’s persistent digging that caused the chipmunk to move his home to a safer location.
We already know that dogs are experts at reading our body language and have the ability to read our emotions by looking at our face. We also know that dogs respond to our tone of voice in much the same way we understand another person’s tone. A new study was recently released that gives us a deeper understanding into how the canine brain processes the emotional tones of our voice to understand how we feel.
Scientists have been trying for years to get into the head of canines to unlock what goes on in their mind. Several years ago Dr. Gregory Berns, a Neuroeconomics professor at Emory University, and his colleagues trained dogs to remain calm and lie quietly in an MRI scanner so they could scan the canine brain with the dog fully awake and unrestrained.
In a nutshell, Neuroeconomics is the study of how we make choices by evaluating risks and rewards, and when interacting with other people. When other researchers learned it was possible to train dogs to lie still inside an MRI scanner, it opened up more studies into how the canine brain works. The surprising finding is that dogs, like us, have a dedicated voice area in their brain that receives and interprets emotions in the voices of humans and dogs.
Two of my dogs, Keikei and Dozer, love to wrestle with each other outside. Both of them enjoy the back and forth, and trying to get them back inside after their morning duty run was frustrating, to say the least. One day I decided to try a new tactic, and when Keikei was at the foot of the stairs, I called her to come, showed her a CANIDAE Pure Heaven treat, and waited for her to bounce up the steps. When she got to the top, I gave her the treat, along with some praise and a mini massage. Treats will definitely get a dog’s attention, but according to a new study, how you greet your dog matters.
The bond we have with other people or our pet doesn’t happen overnight. It’s a process of earning and building on a trust that grows over time. Our human tendency is to gravitate towards people with a positive attitude who are quick to give us a warm smile. It’s nonthreatening, comforting and indicates friendliness. A simple greeting makes you feel good. When touch is added, the emotional response has a lasting effect. Touch is an important aspect of the bonding process with dogs too. A casual touch from someone who cares is a positive sign of an emotional bond. Like us, dogs are social creatures and how we greet them plays a role in their emotional outlook. Dogs need to feel our touch as much as we need contact from people we care about.
One nagging question dog owners have is “Why is my pet always staring at me?” Dog experts may have cracked the mystery to that question. According to a new study, dogs watch what we do, remember an action and imitate it with their own interpretation of what they saw us do.
Our long relationship with dogs has given them plenty of time to study us. They pay attention and can learn through observation. To prove this concept, researchers at the Eötvös Loránd University in Budapest tested dogs to see if they could learn by watching, remember what they saw and then repeat an action on command. According to the scientists, the study shows that dogs can do those things, and provides evidence for the cognitive ability of our canine friends.
Researchers tested eight adult pet dogs ranging in age from 2 to 10 years. The dogs were all female of different breeds, plus one mixed breed. They began with a preliminary test to prepare the dogs for the actual test. Taking turns, each owner had their dog stay and gave the command “Do as I do.” While the dog watched, her owner walked around a traffic cone, rang a bell hanging from a bar, or stuck their head in a bucket on the ground. Returning to the dog, the person waited 5 seconds, then gave the command, “Do it,” and waited for the dog to copy what her owner had done.
