Why Does my Dog do That?

There are some things a dog cannot help doing. If he is going to bite someone, he needs to look at his target, and he needs to bare his teeth.

If he is going to defend himself, he has to tuck his ears back and his tail down and turn aside. In the dark unrecorded mists of wolf history, wolves that had the wits to notice these things had an edge over their more obtuse pack-mates.

Being on the lookout for the fangs or the intent stare of a more powerful member of the pack was a way to avoid unnecessary physical injury from a wolf one had no intention of challenging anyway; being on the lookout for the cringe or the averted gaze of a weaker member was a way to avoid the unnecessary trouble and danger of fighting with a wolf who was prepared to give way without a fight anyway.

Once wolves were on the lookout for unintentionally dropped hints, it became possible to start dropping them intentionally. A wolf that can accurately read a fang or a stare as a threat can avoid a fight and a wolf that can show a fang or fix a stare can then express a threat without a fight.

This evolutionary feedback loop between receivers and senders is what was almost surely behind the development and rituals of the visual signals that wolves, and now dogs, use.

Most of these signals are directly related to the very serious wolf business of dominance and submission within the pack. Dominance and threatening signals include baring the teeth, pricking the ears, and staring.

Submissive and nonthreatening signals include laying the ears back, averting the gaze, approaching obliquely rather than head on, tucking the tail tightly under the belly, and (the ultimate gesture of passive surrender to superior force) rolling over and lying belly-up.

Over sufficiently long time, these signals become ritualized. Every time a wolf lifts his lips and shows his fangs, he is not literally about to bite; rather this is a symbol of threatening intentions, and, at this point in the evolutionary history of the wolf, read as such by other wolves.

Wolves are predisposed to read it that way because of the indisputable fact of evolutionary history that fangs really do bite. Wolves became in turn disposed to use a show of fangs as a threatening gesture precisely because wolves were predisposed to react to fangs as a threat.

Just about all vertebrate animals long ago acquired an innate appreciation of another biological fact that is frequently exploited in visual communication: big things out there are more dangerous than small things. Thus threatening or dominance-asserting wolves try to literally look big.

They stand erect, sometimes astride the animal they are attempting to impress, they raise their tails, they stiffen their hackles.

Submissive or fearful dogs try to look small by crouching low, sometimes even dragging themselves along the ground. It is important to realize that this does not mean that the big- looking wolf is conscious of how big he looks, nor that any other wolf is fooled into thinking he really is big.

Again, these are rituals. But they ultimately derive from the fact that wolves have been wired to react in ways that make these rituals effective.

Dog Feeding Tips

Rule 1: A dog should be fed by the same person at every feeding. This rule is not nearly as important where a couple of house pets are being fed by several members of the same family, as it is where large numbers of dogs are being fed by numerous different kennel personnel.

It is particularly applicable where dogs are in strange environments such as boarding kennels, veterinary hospitals, or show arenas.

Dogs that have become accustomed to one feeder may exhibit all sorts of erratic eating behavior if that person is changed.

Rule 2: Every dog should have its own food and water container. This precaution is not only sound behavioral psychology, it also is just plain good hygiene.

It is especially wise to assign food bowls on an individual basis when your feeding containers are noticeably different from one another. Besides improved feeding technique, certain practical benefits are to be gained from following this rule.

In racing stables, for example, where maintenance of body weight is so important, feeding instructions can be written on the bottom or the side of each dog's feeding container, right next to its name or number.


Rule 3: A dog should be fed in the same place every time it is fed. Whether it be the corner of the kitchen, beside the back-door steps, at the rear of a kennel run, or along the left-side wall of a cage, the site where the food container is placed should remain the same every day.

In fact, everything that's done with the food container should be identical at each feeding. lf you use a push cart or wagon to carry the tub of food to the dogs, always use the same cart and tub.

lf you pre-fill food bowls in the diet kitchen and carry them on the cart, don't decide one day to carry the tub of food on the cart and fill each bowl as you reach the dog.

It may have become boring to you, but to your dog it has become the way of life. A change only serves to disrupt his way of life and to create cause for insecurity.

Rule 4: No dog should ever have its food changed without a good reason. Contrary to popular opinion, dogs do not need a change in food from time to time to keep them from growing tired of the same food all the time.

Many dogs have lived normal, healthy lives by eating the same food throughout their entire lifetimes. In many instances where a dog owner thinks a dog has gotten sick and tired of a food, the dog has just gotten sick from the food.

Not so sick, perhaps, that it really showed, but sick enough to stop eating. When a dog food is deficient, it is not uncommon for a dog eating that food to lose its appetite. Of course, nutritional deficiencies are not the only thing that will cause a dog to lose its appetite.
