| Abstract | A dog harness to which a leash is attachable. When installed on the dog,
the harness acts to inhibit the dog from straining against the leash
without, however, producing a choking action. The harness comprises a
collar that encircles the neck of the dog, and left and right restraint
cables whose leading ends are connected to the front section of the collar
at left and right positions thereon. The restraint lines go loosely under
the left and right foreleg pits of the dog and through respective slip
rings attached to the rear section of the collar adjacent its center, the
trailing ends of the cables terminating in a coupler to which the leash is
attached. When, therefore, the harnessed dog strains at the leash, this
acts to tighten the restraint cables which then impose a pressure on the
foreleg pits. Because these pits are highly sensitive, in order to relieve
this pressure, the dog will then cease to strain against the leash and
thereby again loosen the restraint cable. |

BACKGROUND OF INVENTION
1. Field of Invention
This invention relates generally to harnesses for dogs, and more
particularly to a harness to which a leash is attachable and which acts to
inhibit the dog from straining against the leash without, however,
producing a choking action.
2. Status of Prior Art
As pointed out in the Bloom U.S. Pat. No. 2,233,397, when a dog strains
against a leash attached to the dog harness, it is important that the
harness then avoid a choking effect on the throat of the dog or undue
pressure on throat muscles, cords and nerves, for these may have adverse
effects on the lungs and heart of the dog.
While Bloom discloses a non-choking harness, this harness does not act to
discourage the dog from straining against the leash. Indeed, because the
harness is non-choking, there is nothing to inhibit such straining.
The need exists, therefore, for a harness to break older dogs of the habit
of straining at the leash and for training younger dogs not to strain at
the leash. When a dog strains at the leash, he may, in doing so, wrest the
leash from the hands of its master who then loses control of the dog. But
this is perhaps a less objectionable aspect of straining, for in the case
of a master of advanced years or in a relatively weakened condition,
should the master hold tightly onto the strained leash to maintain control
of the dog, the master may then be pulled to the ground or otherwise
upset, with possibly damaging consequences.
To prevent straining at the leash, hobble type dog harnesses are known,
such as the hobble harness disclosed in the Patience et al. U.S. Pat. No.
2,670,712, which normally permits free movement of the animal but which
restricts the action of the forelegs when the dog attempts to run away or
otherwise get out of control.
The Patience et al. harness includes a conventional dog collar and a
shoulder strap that has hoops at its opposite ends that loosely fit over
the forelegs of the dog. The shoulder strap is adjustable so that the
foreleg hoops can be drawn up but not so tightly as to interfere with
normal movement of the dogs forelegs. However, if the dog strains on the
leash, this strain is also exerted on the shoulder strap, and the foreleg
hoops are then drawn upwardly so that movement of the forelegs is
restrained and the dog will be brought to a halt.
A harness of the Patience et al. type imposes a physical restraint on the
forelegs, and its effectiveness depends on the strength of the dog. Thus
with a small dog, this harness may be fully effective, but with a large
and more powerful dog, the harness may fail to restrain the dog,
particularly if he succeeds in wresting the leash from the hands of his
master.
SUMMARY OF INVENTION
In view of the foregoing, the main object of this invention is to provide a
dog harness to which a leash is attachable and which acts to inhibit the
dog from straining against the leash without, however, choking the dog or
otherwise doing injury to the dog.
A significant feature of a harness in accordance with the invention is that
it does not physically restrain foreleg movement and its effectiveness is
not dependent on the size of the dog or its strength, for the harness will
inhibit straining at the leash, regardless of the breed, size and strength
of the dog.
More particularly, an object of this invention is to provide a harness of
the above type which when the harnessed dog strains at the leash then acts
to impose a pressure on the foreleg pits of the dog, causing the dog to
cease to strain.
A harness in accordance with the invention exploits the fact that in a dog,
the foreleg pits are highly sensitive, and should a pressure be applied
thereto, the normal reaction of the dog is to seek to in some way relieve
this pressure. This sensitivity exists regardless of the breed, size and
strength of the dog, so that as long as foreleg pit pressure is applied,
an immediate reaction will be obtained.
Briefly stated, these objects are attained in a dog harness to which a
leash is attachable. When installed on the dog, the harness acts to
inhibit the dog from straining against the leash without, however,
producing a choking action. The harness comprises a collar that encircles
the neck of the dog, and left and right restraint cables whose leading
ends are connected to the front section of the collar at left and right
positions thereon. The restraint lines go loosely under the left and right
foreleg pits of the dog and through respective slip rings attached to the
rear section of the collar adjacent its center, the trailing ends of the
cables terminating in a coupler to which the leash is attached. When,
therefore, the harnessed dog strains at the leash, this acts to tighten
the restraint cables which then impose a pressure on the foreleg pits.
Because these pits are highly sensitive, in order to relieve this
pressure, the dog will then cease to strain against the leash and thereby
again loosen the restraint cable.
BRIEF DESCRIPTION OF DRAWING
For a better understanding of the invention as well as other objects and
further features thereof, reference is made to the following detailed
description to be read in conjunction with the accompanying drawings,
wherein:
FIG. 1 shows a dog wearing a harness in accordance with the invention;
FIG. 2 is a perspective view of the harness;
FIG. 3 shows the rear section of the harness collar;
FIG. 4 is a side view of a dog wearing the harness without straining on the
leash attached thereto, so that the restraining cables of the harness lie
loosely under the foreleg pits; and
FIG. 5 illustrates a strained leash which acts to apply pressure to the
foreleg pits.
DESCRIPTION OF INVENTION
Referring now to FIGS. 1 to 3, a dog halter or harness in accordance with
the invention includes a collar formed of synthetic fabric strapping or
similar material, having a front section 10 and a rear section 13. The
ends of front section 10 terminate in rectangular metal rings 11 and 12.
As best seen in FIG. 2, each end of front section 10 is folded over one
leg of the ring and is secured to the strap.
Rear collar section 13 is looped through rings 11 and 12 and its ends are
joined together by a rectangular ring 14 to whose legs these ends are
attached to form a closed loop. The respective ends of rear collar section
13 are folded over the opposing legs of ring 14 and are secured to the
strap. Linked to the folded-over ends of rear section 13 are metal slip
rings 15 and 16 which are adjacent to each other on the rear of the rear
collar section loop. All metal rings and other metal components of the
harness are preferably made of stainless or chrome-plated steel, brass or
other non-corroding metal having high strength.
Attached at spaced positions to front section 10 of the collar are right
and left metal D-rings 17 and 18. This attachment is effected by fabric
strips 17S and 18S which are folded over to encircle the strap of the
front section of the collar and are sewn or otherwise secured thereto.
Also provided are right and left restraint cables 19 and 20 formed of
braided fabric or other flexible line material having high strength. The
leading ends of restraint cables 19 and 20 terminate in retractable metal
snap connectors 21 and 22 which are connectable to right and left D-rings
17 and 18 on the front section of the collar, as shown in FIG. 1. Cables
19 and 20 pass through the respective slip rings 15 and 16 linked to the
rear section of the collar and terminate in a metal coupler 23 to which a
leash is attachable.
The right and left restraint cables 19 and 20 are preferably formed of a
single length of cable folded in half to which coupler 23 is linked at its
fold. The portions of cables 19 and 20 extending between the fold and slip
rings 15 and 16 are held together in parallel relation by a metal slider
24 which can be adjusted up or down to lengthen or shorten restraint
cables 19 and 20 to accommodate these cables to the size of the dog being
harnessed.
In installing the halter or harness on a dog D, as shown in FIG. 1, the
collar formed by front and rear sections 10 and 13 is slipped over the
head of the dog to encircle its neck N. Because of the closed loop
formation of rear section 13, its effective length, when installed, is
determined by the distance between rings 11 and 12 at the ends of the
front section 10 through which the loop is threaded. The collar will
therefore adjust itself to the size of the dog's neck, the length of the
loop being short for a small size neck and large for a large size neck.
After the collar is in place, right and left restraint cables 19 and 20 are
guided over the dog's shoulder and under its right and left forelegs
F.sub.r and F.sub.l. Connector 21 is then snapped onto right D-ring 17 on
the front section of the collar and connector 21 is snapped onto left
D-ring 18.
As shown in FIGS. 4 and 5, after the dog is harnessed, attached to harness
coupler 23 is the metal snap connector 26 at the end of a leash 25, so
that the dog is now leashed.
Leash 25 is therefore now coupled to restraining cables 19 and 20 of the
dog harness. When no strain is imposed on the leash, the restraining
cables 19 and 20, as shown in FIGS. 1 and 4, are loose, and while they go
under the forelegs of the dog and lie adjacent the pits of these forelegs
F.sub.r and F.sub.l, they do not press against these pits.
When, however, as shown in FIG. 5, the dog D strains against leash 25, this
strain exerts a pulling force on restraint cables 19 and 20, and as the
cables engage and tighten against the foreleg pits, the cables then impose
an inward pressure against these pits.
As pointed out previously, it has been found that in a dog, the foreleg pit
regions are exceptionally sensitive, and a dog, when pressure is applied
to these regions, will seek immediately in some way to relieve this
pressure. A typical dog will quickly find that this is best done by
relaxing his strain on the leash, for in doing so, the restraint cables
are again loosened and the pit pressure is withdrawn.
While the harness is adapted to fit dogs in a range of sizes, its
effectiveness as a means to control a dog is independent of the size and
strength of the dog, for in all cases the dog will react quickly to
pressure applied to the foreleg pits.
The harness, therefore, is a valuable asset in dog training, for it
provides the trainer who holds the leash with fingertip control of the
dog's movement. It only takes a slight tug on the leash to cause the dog
to react. And while a strained leash also imposes a pull on the dog
collar, this will not produce a choking effect, for the dog will normally
react and relieve the strain on the leash well before this strain reaches
a level producing a choking action.
While there has been shown and described a preferred embodiment of a
strain-reducing dog harness in accordance with the invention, it will be
appreciated that many changes and modifications may be made therein
without, however, departing from the essential spirit thereof. Thus
instead of a two-section adjustable collar, one may use a single section
buckled collar that can be fitted onto dogs having different neck sizes.
