Frequently Asked Questions About Dogs
Why do dogs like people?
Like wolves, dogs are pack animals. They like living in family groups, following a leader, and working together for the good of the whole pack. Prehistoric cave dwellers were the first people to nice that dogs are intelligent, with a superior sense of smell. They also noticed that dogs are excellent hunters and they fast on their four feet. Dogs apparently liked the cave dwellers' home cooking and the way people cold scratch the unreachable parts of the backs. It was the beginning of a friendship that has endured for almost as long as people have existed on earth.
Are there any diseases people can get from dogs or dogs can get from people?
People cannot get most viruses or bacterial infections from dogs and vice versa. Most viruses and bacterial infections are what doctors call species specific, and dogs are a a completely different species from people.  So we can't trade most diseases. We can, however, get parasites such as ringworm (a fungus, not a worm) or mange mites from dogs. Also, rabie is a nasty virus that lives in a dog's saliva and can be passes to humans if the infected dog bites us.

How many hours a day is a dog supposed to sleep?
Sleep time varies greatly by age. Old dogs and young puppies sleep longer. But the average healthy adult pet dog probably sleeps about 16 hours a day. Your dog may sleep from 10-20 hours a day, depending on how busy he is. There are also differences among breeds when it comes to sleep. Working breeds such as Siberian huskies and corgis are more active an usually more high strung. They sleep less. Lap dogs such as papillons and Pekingese sleep more.
When sleeping dogs twitch and make noises are they dreaming?
No one know for sure if dogs dream. But most experts believe dogs do dream about everything from chasing rabbits to greeting their people. Just like humans, dogs' eyelids sometimes tremble during REM sleep. REM stands for "rapid eye movement." For humans, REM sleep means dream time.
Sleeping dogs often twitch, jerk, and make noises that seem funny and make us wonder what they're dreaming about. Just like a person, a dog relaxes all his muscles during sleep.  This is what leads both dogs and people to snort, grunt, and make other noises in their sleep.
Do dogs cry?
Dogs have lachrymal, or tear glands, which constantly produce tears that wash the surface of their eyes. These glands sometimes get clogged up causing a discharge under a dog's eyes that make him look like he's crying. But dogs don't express their sad emotions by shedding tears. They use body language (tail between legs, head down) or sounds (howls and whimpers). Dogs also express grief by laying around, moping, and not eating. They may grieve for anyone in their pack, human or dog, who dies or even just goes away.
Can dogs see what people see?
Most dogs can see in an arc of 250 degrees. Human (and flat-faced dogs such as the Pekingese) have only 180 degrees of vision. this means that dogs spend a lot of time seeing with either one eye or the other (this is called monocular vision while humans have monocular , or two0eyed, vision). That's why dogs are not as good as people are at picking out details or seeing colors. but they're much better at spotting movement, and their eyes work better than ours in dim light. Most dogs lack the detail vision needed t enjoy things like television.  Dogs are not color blind but colors are not as bright to them as they are to humans.
When it ways, does that man the dog is happy?
Experts debate whether or not a wagging tail means happiness, but it definitely means excitement. Tails are always a good indicator of how a dog is feeling but it is not always easy for people to understand what the wagging tail means. Dog body language can be very complicated. The dog's stance and ear and head placement  in combination with the tail communicate the dog's feelings.  It is not a good idea to assume, just because a dog is wagging its tail, it's happy and friendly.
Why do dogs sniff under each others' tails?
Dogs don't consider this behavior to be the least bit rude. The smells under a dog's tail tell where he's been, what he's been doing, and how he ranks socially compared to the dog doing the sniffing. A dog has two scent glands, one on each side of his anus, so sniffing under the tail is an ideal spot to find the facts. A dog who is allowed to sniff another dog under the tail is of a higher rank than the dog being sniffed. It's important for dogs to figure out their rank when they meet other dogs so it's best to allow them this behavior.
Are there any foods that are harmful to dogs?
Dogs often want to eat what their people are eating but not all people food is good, or even safe, for dogs. Chocolate, for example, is toxic to dogs. It can cause liver failure and even death if dogs eat enough of it. Commercially made chocolate candy, which is loaded with more sugar and mile than chocolate, probably won't make a dog sick unless the dog is quite small. But chocolate can have some nasty side effects. It can cause seizures, vomiting diarrhea, ad hyperactivity. There are other foods like onions, grapes, and some nuts that can also be poisonous to dogs. It is best to have your dog stick to his regular diet of dog food no matter now much he may beg for goodies from your plate.
Why do dogs have cold, wet noses?
Moisture helps conduct scent, and most moist or wet things feel cold to the touch. A dog's cold, leathery nose is naturally moist. But dogs also like their noses frequently to help their scenting ability.
Why do dogs lick people?
Dog's, like their wolf ancestors, lick as a way of showing admiration and affection for their pack members. Licking is also a submissive gesture for dogs. When they lick you they are sometimes saying, "I respect your rank above me".
