Are summer shave downs good for dogs? Do dogs love it? Does it really keep them cooler?
As the temperatures rise across the country, many well-intentioned dog parents consider shaving your dogs to keep them more comfortable with the warmth and humidity. After all, we don't want to wear a fur coat during the summer, so why should our dogs?
Common sense tells us that shaving off a dense fur coat would help keep dogs cooler in hot weather, but shaving your dogs down actually robs them of their own natural defense against summer heat and sunburn.
Dog fur is entirely different from human hair. For both dogs and cats, their fur coats help them regulate their temperatures in both cold and warmer weather, similar to insulation for our houses.
Unlike human hair, dog fur has different layers that are responsible for your dog's comfort and temperature control.
If you do decide to trim down your dog's coat during the next heat wave, keep these tips in mind.

Tips to Safely Shave Your Dog

• Clipper blades heat up quickly! Make sure to use cooling clipper blade lubrication and rest the blades throughout the grooming session to avoid painful dermal burns.
• Better yet, leave it to a professional. At-home grooming attempts may result in accidental lacerations and burns. In an effort to save a few dollars, you may find yourself at the emergency clinic getting your dog stitched up.
• Leave at least an inch of fur. Leaving too little fur puts your dog at risk for sunburn, and a clip too close to the skin puts your dog at risk for ingrown hairs and irritated skin.
• How do you know if your dog is at risk for sunburn? Check your dog for visible pink skin around the face, paying special attention to areas with thin hair, such as the ear tips. If you can see pink skin, it is possible that your dog could be vulnerable to sunburn.
• If you are considering shaving because your dog has developed hot spots, seek help from your veterinarian. Hot spots are tender and may make your pup snippy when being groomed.

While shaving your dog down in attempts to help them beat the summer heat is typically discouraged, there are times the clip down may be of benefit. It a dog has a matted coat and is likely to often be wet, this dog's thick damp coat is more likely to promote the development of skin infections or even to become a nest for flies. This can lead to a nasty condition quickly - maggots in the fur.
For the majority of our dogs, if the fur isn't already matted, keeping the coat well-brushed is key. Coats that are kept well-brushed and mat-free allow for good air circulation through the hair, which in itself can actually have a cooling effect. On the contrary, matted, unkempt hair coats stifle air circulation, do little to help cool the body, and make the dog more likely to develop skin infections such as hot spots. Even for dogs that are prone to hot spots, routine brushing is advised before jumping to the clip down. Simply put, daily brushing is a crucial part of your routine during the hot, summer months.
I hope this gives you great information about the pros and cons of shaving your dog during the summer months.

Making Sense of Your Dog’s World

A couple weeks ago I was watching the news when they featured a segment called "How Long Do Dogs Remember?" all about the canine memory. According to this program, dogs have a memory span that's about 2 minutes long. But how true is that? I wanted to find out.  Based on what I have learned from various behaviorists and my own vet school studies, this estimate is about right…at least for some things. I suppose that is one thing we love about dogs; they're always ready to start a brand new day without the worries of the one before it.  For example, let's say a dog lover leaves for work. They come back 8 hours later and the dog is so happy to see them, you would think the dog hadn't seen their human for days! A little later the same pet parent might run to the store for half an hour. When they come home, the reaction is just the same: total joy and excitement from their dog. Many folks would say that no one is as happy to see them as their dogs.  After a particularly bad day, wouldn't it be tempting to leave just so you could come home to such a happy greeting? (I know I've thought about it.) Speaking of memory, dogs are pretty unique in some of the other way that they interact with the world.  Your dog's senses allow him to behave and perform in ways nothing short of magical. Dogs perceive the world differently from the way we do – we share the same senses, but with remarkable differences. The Nose Knows The first thing your dog does when you walk in the door is sniff your legs. Dogs gather a lot of information from a quick sniff of their environment – both physical and emotional details. He smells where you've been and even how the experience affected you. Dogs sniff each other and each others' secretions constantly, monitoring various physiological and emotional changes on an ongoing basis. Dogs live in a world of odors. Their sense of smell is their most refined sense; in fact, it is so refined a bloodhound can identify scales of skin shed by humans three days previously. They can also detect drugs in hidden in body cavities, can sniff out rats, termites, bombs, missing persons, bodies drowned or buried in snow or rubble, and even the presence of melanoma cancer. Their noses are about as sensitive as our eyes. The scrolled, scent membrane inside a dog's nose is about four times greater in area than the equivalent smell organ in humans. In the dog's nose, there are over 200 million scent receptors in the nasal folds compared to our 5 million. Moisture on the nose helps to capture scent and transmit it onto odor-sensitive nasal membranes, which cover the nose's wafer-thin turbinate bones. These bones comprise of convoluted folds, ensuring that the tiniest amount of scent is captured within them. See, Spot Have you ever noticed how your dog acts when you are approaching him from a distance? He sees you immediately, and he stops and stares; but it's obvious that he doesn't know who is coming toward him. You start talking to him, perhaps calling his name, but he is still unsure, although he will act interested. Finally, when you get close enough to him that he picks up your scent, he will run to you happily. Your dog trusts his sense of sight the least. However, while smell is his most refined sense, sight is his strongest. Dogs have no good biological reason to identify different colors. Though they can distinguish between certain colors, their color vision is limited and the colors may appear muted to them. Dogs see more clearly than humans do in dim light. This allows for increased movement definition of prey animals. Although their ability to see detail is limited, they are quite exquisitely sensitive to movement, and are able to pick up even very slight movement of hiding prey. A stationary object may not be noticed from a distance, but the dog will see it as soon as it makes a move. Hear Ye, Hear Ye You must have experienced the result of your dog's super hearing ability. You are sitting in your favorite chair reading or taking a nap, with your faithful pet lying at your feet. It's blissfully quiet – not a sound to be heard. Suddenly your dog leaps to his feet and begins barking loudly, his protective bark, and you run to the window to see who is approaching. But there's no one there. At least not at first. It takes moments before someone actually comes into view and walks by the house or into the yard. The dog's ability to hear is incredibly acute compared to humans. They can hear sounds over a wider range of frequencies and a greater distance than we can. Also, experiments have shown that a dog can locate the source of a sound in about six-hundredths of a second. Their highly mobile ears capture sounds and funnel them down to the eardrum. You might see your dog cock one ear to capture the initial sound, and then use both ears to catch the maximum number of sound waves. Protection and guard dogs use their sense of hearing, along with their sense of smell, to detect possible intruders, sometimes from great distances. Touch and Go Touch is the first sense the dog develops and remains a powerfully important sense throughout his life. Mothers begin touching newborn puppies almost immediately after birth by licking and nuzzling. Touch-sensitive hairs called vibrissae, which are capable of sensing airflow, develop above the eyes, on the muzzle, and below the jaws. The entire body, including the paws, is covered with touch-sensitive nerve endings. The physical sense of touch is very sensitive, although dogs do have a high threshold of pain. Body sensitivity varies among dogs, but most enjoy being stroked around the head, chest and back. The most sensitive nerve endings are along the spine and towards the tail, and dogs show great enthusiasm in pats or extended rolls and slides on the grass. The Taste Test Dogs use their large tongues to lap up water, but they have few taste buds in comparison to humans, approximately one for every six, most of them clustered around the tip of the tongue. They can detect sweet, sour, bitter, and salty tastes. However, your dog has no real sense of taste as we know it; he smells rather than tastes. It's possible that dogs gain more information about food from their sense of smell than from taste. This may account for their desire to for indiscriminate chewing or eating. How Do They Do That? Then there all of the other things that dogs can do that seem to defy explanation – a kind of sixth sense. They seem to be able to detect changes in the earth's magnetic field; they may, to some extent, be able to detect infrared wavelengths of light, a kind of heat that living animals emit; they can detect sudden changes in barometric pressure when a thunder storm is brewing; they can detect vibrations from earthquakes much sooner that instruments; they can find their way home from long distances over unfamiliar terrain. They can even detect your mood. Do dogs have a sixth sense? Maybe they do. Or maybe, like some believe, it can all be explained by already-known biological mechanisms. However you explain their abilities, dogs and their sensitivities are truly wondrous.
