Top Ten Canine Myths
Hey, Rover would rather be outside all day than cooped up inside!False. Dogs are strongly pack-oriented animals. They prefer best to be with their pack whenever possible. If you are inside, they will want to be inside with you. If you are outside, again, they will want to be with you. If you are at work, while they would still like to be with you, this is not usually possible. In this case, does it matter whether the dog is kept inside or outside? It turns out that many dogs behave well when kept inside; bark, dig, and whine while kept out in the yard. Why is this? Your home is the "den." Dogs prefer to be closer to the center of the den -- the place where the pack's smells are most acute. While some dogs are happy to stay outdoors during the day while the rest of the pack is gone to work, a great many dogs develop behavioral problems as a result of daily "expulsion" from the den.
In addition, a dog with access to a large territory may feel compelled to "defend" all of it, resulting in other types of problems: frantic barking at "intruders," and so on. Restricting the amount of territory it has to protect may reduce this type of behavior.
A good compromise for many dogs is access both to a restricted part of the house and a restricted part of the yard. The inside-outside access keeps him from feeling ejected from the "den" without having too much territory to defend. A dog that can't be trusted inside and is destructive outside will probably benefit the most from being crated during the day. With most dogs, if you crate them through puppyhood (which also helps with housebreaking), by the time they are mostly adult (from 8 months to 24 months of age depending on the breed) you can start weaning them off the crate. Because they are used to spending the time in the crate quietly, they will form the habit of spending that same time quietly whether in the crate or not as adults.
Well, OK, but it's different in the country, isn't it?It is an absolute myth that living in the country confers greater latitude in the dictum "thou shall keep thy dog constrained to the immediate environs of the pack." Country dogs allowed to run free get shot by hunters or farmers protecting their livestock. They get into fights with other dogs over territory. They can kill livestock, fight and tassle and get disease from wild animals, and be hit by cars on the highway. They become increasingly aggressive as they vye for larger and larger perimeter boundaries to their territory, and they no longer relate to YOU as the leader of their pack. Also, don't forget that intact animals will breed and add to the overpopulation problem.
This same misconception leads people to dump unwanted dogs "in the countryside." Most such dogs die a painful death, either by slow starvation, injuries from being hit by a car or in a fight with another animal, or they are shot by farmers protecting their livestock. The countryside is not some sort of romantic haven for stray dogs.
When dogs are mad at people, they do all kinds of spiteful things.First remember that "undesireable behavior" is in the eye of the beholder. To the dog, it's perfectly alright to dig, to bark, to chase after other dogs, etc. This doesn't mean you can't control these behaviors, of course, but it does mean that the dog isn't doing them "to spite you." The dog hasn't a clue that it's not to do these things unless you train it not to. And it has to understand what you want from it!
When dogs start undesirable (to humans) behavior, its best to try to understand the source of this behavior. Often it stems from the frustration of being left alone. Dogs are very social animals. One positive solution is to make sure your dog is properly exercised. Exercise is a wonderful cure to many behavioral problems and dogs just love it. Do check with your vet for the proper amount of exercise for both the age and breed of any dog. Another solution is obedience training. The point is, your dog needs your attention, whether it is by taking it out on a walk, training it, or both.
Ah, but my dog always looks GUILTY after he's done something like this!No. He's reacting to your body language and emotions. When you come in and see the toilet paper all over the floor, you get mad. The dog can tell that you are upset and the only thing he knows how to do is to try and placate you, as the alpha. So they try and get you out of your bad mood by crouching, crawling, rolling over on their backs, or avoiding eye contact. You interpret the dog as acting "guilty" when in fact the dog hasn't the faintest idea of what is wrong and is simply hoping you will return to a better mood. The important thing to remember is that if your dog finds that it cannot consistently predict your anger or the reasons for it, it will begin to distrust you -- just as you would someone who unpredictably flew into rages.
This is why it's so important to catch dogs "in the act." That way you can communicate clearly just what it is they shouldn't do. Screaming and yelling at the dog, or punishing it well after the fact does not tell your dog what is wrong. You may in fact wind up teaching it to fear you, or consider you unreliable. You must get your dog to understand you, and you have to work on the communication gap, as you are more intelligent than your dog.
Preventing your dog from unwanted behaviors coupled with properly timed corrections will go much further in eliminating the behavior from your pet than yelling at it.
In fact, you should not yell at, scream at, or hit your dog, ever. There are much more effective ways to get your point across. Try instead to understand the situation from your dog's point of view and act accordingly. The techniques in this chapter approach problems with this in mind.
Crating a dog is an awful thing to do to it and they hate it.Again untrue. Dogs are by nature den animals. When properly introduced to a crate, most dogs love it, and they will often go into their crates on their own to sleep. Of course, no dog should be left in the crate so long that it must soil the crate. It's a wonderful tool to use for housetraining, but puppies are not physically equipped to go for more than three or four hours without going to the bathroom. And all use of a crate should be done with an eye toward eventually weaning the dog off of it. There are only a few dogs that must always use a crate while you are gone. Afterwards, it is a very useful thing to have -- for example if at all possible your dog should always ride in the car in his crate.
Crating a dog works to prevent the dog from doing many of the behaviors you don't want it to. What your dog does not do does not develop into a habit and thus requires no correction. Second, it means that when your dog does have an opportunity to engage in the unwanted behavior, you are around (because you're home to let it out) to give a proper and timely correction.
As the behavioral aspects pointed out above, reducing the territory to protect and keeping it in the den are also positive things from the dog's point of view, reducing the overall stress that it experiences.
Ya gotta show a dog who is boss.To some extent, this is true. But what many people think this is comprised of are usually quite wrong. You don't show a dog "who is boss" by hitting it, yelling at it, or via other methods of punishment. You show a dog who is boss by being its leader. Show it what to do, how to behave. Most dogs are waiting for you to take the lead. There are actually only a very few dogs who will actively challenge you for "top dog" position. Rather, most dogs take the "top dog" position because their owners have made no effort to do so, and not only that, their owners don't recognize what is happening -- until the dog starts correcting them for their misbehavior!
Interestingly, many forms of behavior that have been touted as showing dominance over a dog backfire badly. This is because in many cases dogs really aren't contending for the "top dog" position: applying techniques to "show him who is boss" in these instances results in the dog being alienated from you and distrusting you because you corrected it for no good reason. The alpha roll, long touted as the "best" of these methods is in reality a last ditch, all out correction. It's what you do to your teenager after he's taken a joyride in your car and totalled it, not when he first asks you for the keys. Being unfair to your dog in this way can create a fear biter, one who has lost all hope of being treated fairly and defends himself the only way he knows how.
Biting
It is natural for young puppies to bite and chew on people; however DON'T let them do this.
If your dog is a puppy, yelp pitifully when it chomps on you, and replace your hand with a chew toy; praise heartily when the chew toy is used instead. If it persists, stand up and stop playing with it. It is no fun for the puppy if you stop interacting with it, and it will learn to stop chewing on you fairly quickly.
With older puppies and dogs, say "NO BITE" sternly and withdraw your hand.
If the dog goes through a cycle where it seems to be infuriated by your correction and returns ever more aggressively to chew on you, call a timeout and put the dog where it can't get to you, preferably its crate. When it calms down, let it back and be prepared to interrupt the cycle if it starts again.
Never put up with a puppy biting or mouthing you. When they are adult, the problem will be far more severe.
Tug of WarThe Monks (and former Monk, Job Michael Evans) seem to believe that playing tug is a form of "teaching" the dog to use its teeth, and therefore a precursor to the dog's learning to use its teeth as a weapon. In their view, you should never play tug with a dog. On the other hand, there are many people and organizations, especially in obedience and working dogs (patrol, narcotic, and search and rescue) that actively use tug of war as a reward and a way to build up a strong play response. People with hunting retrievers never play tug of war for fear of creating a "hard mouthed" dog (one that mangles the birds it retrieves).
Dealing with the possible aggression incurred in tug of war is probably more constructive than never teaching your dog to use its teeth. Besides, studies on canine aggression show that even extremely docile dogs can be provoked to show aggression. Houpt and Wolski in their book _Domestic Animal Behavior for Veterinarians and Animal Scientists_ note: "Growling is an aggressive call in dogs, and is commonly known. It is interesting evolutionarily that even the most placid dog can be induced to growl if one threatens to take a bone away from it. A scarcity of food in general can increase aggression ..., but bones seem to have particular value even for the satiated dog."
This can hinge on whether you (as the owner) can distinguish between challenges and playing. If the dog is playing when doing TOW, there's no problem. If it *is* challenging you doing this, you need to 1) recognize the challenge (versus just playing) 2) win and 3) stop the TOW and correct its challenge to your authority. If you can't make the distinction, then don't play tug-of-war with it. Couple any tug-o-war games with the command "Give" or something similar so that the dog learns to immediately let go ON COMMAND. If it doesn't, that's a challenge, and you need to deal with it. Teach your dog what "give" when you start playing this game with it. When you know that your dog understands the command, then periodically reinforce it by having your dog "give" at random times. This becomes a form of keeping your alpha position as mentioned earlier in this article. And tug of war, properly implemented, is an intensely rewarding game for many dogs, making a good "treat" during training sessions, for example.
People FoodFeeding your dog "people food," i.e., table scraps and such is a poor idea. First, you may encourage your dog to make a pest of itself when you are eating. Second, feeding a dog table scraps is likely to add unneeded calories to its diet and your dog may become overweight. Third, if your dog develops the habit of gulping down any food it can get, it may seriously poison or distress itself someday.
Some guidelines. Do not feed the dog anything but dog food and dog treats. You might add vegetable oil or linatone to the food to improve its coat. There are other foods that you may want to add to improve its diet such as vegetables, rice, oatmeal, etc., (check with your vet first for appropriate food to meet the dietary need you want to address), but always feed them to the dog in its dish, never from your plate or from your hand while you are eating.
Discourage your dog from begging at the table by tying it nearby (so that it does not feel isolated from the social activity) but out of reach of the table. After you finish eating, feed the dog. Tell your dog "no" or "leave it" if it goes for anything edible on the floor (or on the ground during walks!), praise it when it obeys you. Teach it that the only food it should take should be from its dish or someone's hand.
If you are concerned about the "boring and drab" diet for your dog, don't think of food as a way to interest it! Play with it, take it out on walks -- there are many other and better ways to make life exciting for your dog.
