Getting your dog to chew the right thing

Ian Dunbar is a veterinarian, animal behaviourist and dog trainer based in Berkeley, California Canine chewing sprees can be as expensive as they are frustrating. My most expensive case history involved an Akita that meted out $10,000 worth of damage to the interior of a Mercedes in a little under half an hour. In most situations, doggy devastation occurs in the owner's absence, usually when the dog is left home alone.

Home Alone

Frustrated at their inability to correct the dog when it misbehaves, many owners resort to punishing the dog for welcoming their return home. But perhaps there is a better way. Indeed, teaching a dog how to entertain itself and wile away the long hours when left at home alone is one of the most important ingredients of domestic education.

Dogs chew out of necessity, boredom, anxiety or enjoyment. Puppies especially have a strong urge to chew. Not only do they chew to relieve the irritation and inflammation of teething but also, pups characteristically investigate the environment with jaws and paws. Everything is pawed, sniffed, licked or chewed to see whether it is sentient or inanimate, whether it is tasty or yucky and whether it is indestructible or fun to destroy. Moreover, regular chewing is essential for maintaining the health of the dog's teeth, jaws and gums. Thus, chewing is a perfectly normal, natural and necessary canine behaviour.

The problem is not that the dog chews but rather, what the dog chews. Consequently, prevention and treatment of wanton house destruction should focus on redirecting the dog's chewing proclivities exclusively to articles that the owner considers to be both appropriate and acceptable chew toys.

If we try to look at things from the dog's point of view, there are only so many things a dog can do when left at home alone for long periods of time. It is not as though the dog can watch the soaps on the television, do needlepoint or complete The Times

crossword puzzle. When left alone, the dog's choices of recreational activities are severely limited; Really all the poor dog can do is chew, dig, bark or snooze. Many chewing extravaganzas are the result of boredom - simply a result of the dog's relentless quest for some way to pas the time of day.

Separation anxiety is often cited as a cause for the dog's owner-absent destructive behaviour. Dogs chew to relieve the anxiety of being left alone. Dependent dogs react worse to weekday solitary confinement if they are allowed unrestricted access to their loving owners at other times, for example during evenings and weekends.

It is vitally important to foster confidence and independence by actively teaching a companion dog how to enjoy the peace and quiet of it's own company, and specifically how to amuse itself and pass the time of day when its human companion is not at home. Otherwise, the dog will focus on the owner's absence and fret, panic and pine for the absent owner.

Thus, when at home it is a sound polity to periodically confine the dog for short periods with chew toys for amusement. Not only will the dog become accustomed to confinement but also, the owner may monitor the dog's behaviour when confined.

Many dogs, however, are not the least bit anxious when their owners leave. In fact, they relish being left at home alone - a wonder opportunity to act like dogs specifically to have a good chew without catching any flak from their killjoy owners. Perhaps separation relief would be a more accurate descriptive term than separation anxiety for the etiology of most dogs' owner-absent chewing.

Chew toys

Whatever the cause of chewing - animal nature, boredom, anxiety or fun- the solution entails redirecting the dog's chewing tendencies to appropriate Chew toys. Chew toys should be both indestructible and non-consumable.

The choice of chew toy depends on the strength and compulsive nature of the dog's

chewing. Rawhide, Kongs and open-ended long bones (e.g., beef femurs, now commercially available in pet stores_ are fine with most dogs but not others. When compared to the cost of reupholstering one couch, $100 worth of chew toys seems to be a pretty wise investment for dog owners.

For some dogs, just putting down a few chew toys is sufficient to successfully redirect chewing activities. However, most owners must actively train their dogs to enjoy chew toys. One way to do this is by lure-coursing stuffed chew toys along the kitchen floor on the end of a string. Both Kongs and bones are hollow and may therefore be stuffed with goodies to heighten the dog's interest and entice it to chew them exclusively. To prevent the dog from getting fat, ensure the treats are part of the dog's daily diet (primarily kibble, high-fibre biscuits and the occasional liver treat) Use kibble or biscuits to cork the end of each bone or toy so the dog may quickly bite off the protruding part of the treat and then extricate the rest only after worrying at the toy for several minutes.

Also, try squishing a really tasty treat (cheese or freeze=-dried liver) into the bony trabeculae in the middle of the marrow cavity of a bone, so the dog may smell the treat, see the treat (and maybe even talk to the treat) but can never get it out.

Instant Gratification

Different shaped dog biscuits are ideal for stuffing Kongs; some shapes go in and come out easily, while others have to be forced in and require human fingers to extract. Thus, after the owner leaves the house, the dog will be instantly required for investigating chew toys and then rewarded again for working on them for awhile, where after the dog will continue to nibble and gnaw at the chew toys for quite sometime knowing there are more (tastier) treats inside.

On returning home, instruct the dog to fetch it's chew toys and pull the biscuits from the
Kongs and use a pencil to poke out the tasty treats from the bones. Human manual dexterity and tool use never fail to impress the canine mind, making the dog more inclined to search for chew toys when it wakes from its afternoon nap in expectations of the owner's return.

The above procedures maximize the likelihood the dog will chew chew toys during the two crepuscular (dawn and dusk) and unintentionally trained peaks in owner-absent chewing activity- immediately after owners leave home and immediately prior to their return.

Passive Training

Apart from using treats to increase the intrinsic value of chew toys and actively training dogs to enjoy chewing chew toys, passive training techniques offer a user-friendly time-efficient, sure-fire way to cement to the dog's chew toy habit. Passive training routines simply involve setting up the training scenario, whereby the dog trains itself. Wonderful! When away from home, confine the dog to a sing room (e.g., the kitchen or utility room) that contains nothing for the dog to destroy. Obviously, if confined to the kitchen the dog cannot destroy living room carpets, curtains and furniture. Also, if confined to the kitchen with ought for company but half a dozen intelligently stuffed chew toys, the dog will quickly develop a chew toy habit.

Similarly, when at home the dog may be safely and profitably left for variable periods in its long-term confinement area when the owner is unable to supervise the dog. Not only will this encourage the dog to chew, chew toys but also, it will help the dog adjust to confinement when left at home alone. Alternatively, the owner may confine the dog for short periods to a smaller area, such as the dog's bed or crate, with nothing within reach apart from a couple of stuffed chew toys.

There is a plethora of obnoxious doggy habits which may be prevented if the dog is otherwise gainfully employed chewing chew toys.

David Letterdog's List of 10 Things a Dog Cannot Do While Chewing a Chew toy

Chew carpets, curtains, couches, clothes, chair legs, children's toys and electrical cords or
consume famous books on dog behaviour.
Bark incessantly. The dog may still bark at disturbances, but it is less likely to bark
recreationally because now it is busy chewing recreationally.
Run in ever-decreasing obsessive compulsive circles, anxiously chasing its tail, or excessively
licking or chewing paws and the root of its tail, causing self mutilation.
Play-bite or mouth your hand, nip ankles, grab the lead or play tug o-war with your tie or
trousers
Destroy garden furniture and hoses, consume cat faeces and dog stools or eat flowers and
poisonous plants.
Dig. Certainly the dog can hold a chew toy in its jaw and dig, but if really working at treats
inside the chew toy, it would hardly be inclined to dig a hole to bury the chew toy.
Noisily lick private parts in the company of great aunts or children.
Lick your face with the same tongue that was used to perform number 7.
Borrow the car, write bad checks or run up the charge card. (just checking to see if anyone is actually reading this article.)

Become bored or anxious and otherwise dream of bolting through the front door or escaping from the yard.
