| Abstract | A leash-controllable dog harness and leash assembly adapted to inhibit a
dog from straining against a leash held by an individual walking the dog.
The harness includes a shoulder junction having a pair of slide openings
therein overlying the dog's shoulder intermediate its left and right
forelegs, each having a crotch leading to a sensitive pit, a chest
junction lying adjacent the dog's chest intermediate its left and right
forelegs, and a pair of harness straps extending between the shoulder and
chest junctions on opposite sides of the dog to conform the harness to the
body of the dog. Left and right restraint straps extending from the chest
junction pass through the corresponding foreleg crotches and then through
the opening in the shoulder junctions to terminate in a link coupling the
harness to the leash. When the leash is strained, the restraint straps
linked thereto are caused to ride up the crotches to engage the sensitive
foreleg pits and impose pressure thereon inducing the dog to relieve this
pressure by slowing down or coming to a halt to loosen the cables. |

BACKGROUND OF INVENTION
1. Field of the Invention
This invention relates generally to a dog harness which is connected to a
leash held by an individual walking the dog, and more particularly, to a
controllable dog harness and leash assembly adapted to inhibit the dog
from straining against the leash and inducing the dog to come to a halt or
to walk at a pace acceptable to the leash holder.
2. Status of Prior Art
A leash is a chain or strap attached to the collar or harness of a dog, the
leash being used to lead the dog or to hold it in check.
As pointed out in the Bloom U.S. Pat. No. 2,233,397, when a dog strains
against a leash attached to a 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 and to hold the dog in check.
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, it 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 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 go 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 dog's 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.
My prior Sporn U.S. Pat. No. 4,964,369, discloses a dog harness acting to
inhibit the dog from straining against the leash without, however,
producing a choking action. The harness comprises a collar encircling 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 cables 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, the trailing ends of the cables
terminating in a coupler to which the leash is attached.
When 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, the dog, in order to relieve this
pressure, will then cease to strain against the leash and thereby again
loosen the restraint cable. While a harness of the type disclosed in my
prior '369 patent is effective for its intended purpose, it requires a
collar whose size is appropriate to the neck size of the dog on which it
is installed.
My above-identified copending patent applications and my prior U.S. Pat.
Nos. 5,359,964 and 5,329,885 disclose a collarless leash-controllable dog
harness adapted to inhibit a dog from straining against the leash held by
an individual walking the dog, the harness inducing the dog to come to a
halt or to walk at a pace acceptable to the leash holder.
In this collarless harness, the straps and cables which from the harness
run between a shoulder junction overlying the shoulder of the dog and a
chest junction lying adjacent the chest. When this harness is installed on
a dog, one harness strap passing through the right foreleg crotch, the
other strap running through the left foreleg crotch. Should the harnessed
dog strain against the leash, this causes both straps to ride up the
respective crotches to impose pressure on the highly-sensitive foreleg
pits, whereby in order to relieve the resultant discomfort, the dog then
relaxes the strain.
The harnesses disclosed in my copending applications and in my prior U.S.
Pat. Nos. 5,359,964 and 5,329,885 have distinct advantages over that
disclosed in my prior '369 patent, for it does not entail a collar. But in
both instances, control of the dog is effected by applying pressure to the
highly-sensitive foreleg pits which induces the dog to relax the strain on
the leash.
SUMMARY OF INVENTION
In view of the foregoing, the main object of this invention is to provide
an improved leash-controllable dog harness and leash assembly of
relatively simple and inexpensive design adapted to apply pressure to the
highly-sensitive pits of the dog's forelegs and thereby inhibit the
harnessed go from taking any action not acceptable to the holder of the
leash.
Among the significant features of an improved leash-controllable dog
harness in accordance with the invention are the following:
A. The harness includes no neck collar that must be fitted to the neck of
the dog being harnessed;
B. The harness does not physically restrain or hobble foreleg movement of
the dog;
C. The effectiveness of the harness does not depend on the size and
strength of the dog or on its breed, for it is effective on all dogs of
all breeds; and
D. The harness lends itself to color and fabric coordination of the leash
and the harness to provide a fashion or designer assembly.
More particularly, an object of this invention is to provide a harness of
the above type which includes a pair of restraint straps which pass
through the respective foreleg crotches of the harnessed dog and are
coupled to a leash whereby when the leash is strained, the cables then
ride up the crotches to engage and apply pressure to the highly sensitive
foreleg pits.
Still another object of the invention is to provide a leash-controllable
harness that includes straps of adjustable length formed of high-strength
fabric webbing and restraints cables formed of a braided fabric so that
the harness which is comfortable to wear may be quickly installed on the
dog, and may be mass-produced at relatively low cost.
Yet another object of this invention is to provide soft, protective sleeves
for the restraint straps of the harness which prevent the cables sliding
through the sleeves from chafing or otherwise irritating the dog.
Also an object of this invention is to provide a harness of the above type
which is adapted to limit the amount of pressure applied to the sensitive
foreleg pits to prevent undue discomfort.
Briefly stated, these objects are attained by a controllable dog harness
and leash adapted to inhibit a dog from straining against a leash held by
an individual walking the dog, the harness inducing the dog to come to a
halt or to walk at a pace acceptable to the leash holder. The harness
includes a shoulder junction having a pair of slide openings therein that
overlies the dog's shoulder intermediate its left and right forelegs, each
having a crotch leading to a sensitive pit, a chest junction lying
adjacent the dog's chest intermediate its left and right forelegs, and a
pair of harness straps extending between the shoulder and chest junctions
on opposite sides of the dog to conform the harness to the body of the
dog.
Left and right restraint straps extending from the chest junction pass
through the corresponding foreleg crotches and then through the respective
openings in the shoulder junction to terminate in a link coupling the
harness to the leash. When the leash is strained, the restraint straps
linked thereto are caused to ride up the crotches to engage and impose
pressure on the sensitive foreleg pits, thereby inducing the dog to
relieve the pressure by slowing down or coming to a halt to loosen the
cables.

DETAILED DESCRIPTION OF INVENTION
First Embodiment
Referring now to FIGS. 1, 2 and 3, there is illustrated in these figures a
controllable harness and leash assembly in accordance with a preferred
embodiment of the invention suitable for dogs whose sizes may range from
small to large, for the harness is adjustable to the size of the dog on
which it is installed.
The harness includes a shoulder junction 10, (shown separately in FIG. 3)
formed of an arrow-shaped plate of brass, plastic or other suitable
high-strength material. Shoulder junction 10 is provided at its narrow
shaft upper zone with a pair of slide openings S.sub.1 and S.sub.2, and at
its lower arrow zone with slots defining converging left and right side
arms A.sub.1 and A.sub.2. When the harness is installed on a dog D, as
shown in FIG. 1, shoulder junction 10 then overlies the shoulder of the
dog intermediate its left and right forelegs F.sub.1 and F.sub.2.
Threaded through the respective slide opening S.sub.1 and S.sub.2 of the
shoulder junction 10 are the left and right sections 11L and 11R of
leash-linking strap 11 having at its midsection 11M a coupling ring 12.
The left and right sections of the strap cannot be pulled through shoulder
junction, for this action is blocked by midsection 11M. Coupling ring 12
as shown in FIG. 1 is linked to the retractable clasp 13 which terminates
the leading end of a leash 14 formed of the same fabric webbing as that of
strap 11.
Also included in a chest junction 15 formed by a short transverse fabric
strap having left and right rings 16 and 17 secured to its opposite ends.
When the harness is installed, chest junction 15 then lies against the
chest of dog D intermediate its left and right foreleg crotches.
The left section 11L of the leash-linking strap is coupled to ring 16 of
the chest junction 15 and the right section 11R is is coupled to ring 17
of this junction.
Extending between left arm A.sub.1 of shoulder junction 10 and left ring 16
of chest junction 15 on one side of the dog is a fabric strap 18 provided
with a tri-slide 19 that is adjustable along the strap to vary its length
to accommodate the harness to the body of the dog. Obviously the bigger
the dog the greater is the distance between its shoulder and chest and the
greater must be the length of strap 18 which runs between the shoulder and
chest junctions. Similarly, extending between right arm A.sub.2 of
shoulder junction and right ring 17 of the chest junction 15 on the other
side of dog is a fabric strap 20 provided with a tri-slide 21 to adjust
the length of this strap.
The left section 11L of the leash-linking strap 11 is provided with a
tri-slide 22 to adjust the length of strap 11 and a releasable buckle 23.
The right section 11R of strap 11 is provided with a tri-slide 24 and a
releasable buckle 25. When released, the buckle opens up the harness so
that it can be installed on the dog or taken off.
The strap sections 11R and 11L extend from the chest junction 15 to the
shoulder junction 10 through the respective foreleg crotches of the dog
and when the leash is strained, the leash coupling ring 12 which is joined
to the midsection 11M of strap 11 causes the strap sections to ride up the
foreleg crotches to engage the foreleg pits.
Buckles 23 and 25 on strap sections 11R and 11L serve a dual function, for
they not only permit the user of the harness to quickly install the
harness on the dog and to just as quickly detach the harness, but the
buckles also function as a limit on the extent to which the strap sections
can apply pressure to the foreleg pits and to thereby avoid excessive
pressure which may cause undue discomfort to the dog.
When the leash is strained, coupling ring 12 is pulled away from the
shoulder junction in to cause the strap sections 11R and 11L to pull out
of slide openings S.sub.1 and S.sub.2 of the shoulder junction. When the
buckles 23 and 25 on these strap sections reach the slide openings,
further withdrawal of the strap sections is arrested, for the buckles are
blocked by the slides openings.
Operation
When the harnessed dog is led by an individual holding leash 14 at an
acceptable pace, and the walking dog does not then strain against the
leash, the harness remains fairly loose and comfortable, and the strap
sections 11L and 11R which act as restraint cables passing through the
foreleg crotches are then disengaged from the sensitive pits of the dog's
forelegs.
However, should the dog lurch ahead or seek to increase its pace so that it
is moving faster than the individual walking the dog, the leash held by
the individual will then be strained. This strain acts to exert a pull on
strap sections 11L and 11R which will concurrently ride up the foreleg
crotches to engage and press against the sensitive foreleg pits. The
resultant discomfort will induce the dog to relax the strain on the leash
so that the cables no longer press against the sensitive pits.
However as pointed out previously, the buckles on the strap sections limit
movement of the strap sections to prevent undue discomfort.
Protective Sleeves
In the harness shown in FIG. 2 the strap sections 11L and 11R go through
the left and right foreleg crotches and function as restraint cables. When
the restraint cables are tightened, they rub against the surface of the
dog. With continued use this action may cause chafing or irritation.
To avoid such chafing without however interfering with the ability of the
harness to control the dog on which it is installed, there is mounted on
each cable an elongated protective sleeve 26. This sleeve is shown in
connection with strap section 11L in FIGS. 4, 5 and 6. Sleeve 26 has a
tubular inner liner 27 formed of woven or knitted nylon or similar smooth
fabric material, on which is secured an outer coat 28 of Sherpa, cashmere
wool or other soft, non-abrading material.
The inner liner 27 of the sleeve is preferably fabricated of stretchable
material so that when mounting the sleeve on a strap, the sleeve can
expand to allow a slide or any other element mounted on the strap to pass
through the sleeve.
Designer Assembly
All straps included in the harness shown in FIG. 1 are made of a fabric
webbing of the same width, and the leash is also made of fabric webbing of
the same width so that the harness and the leash are decoratively
coordinated. In practice, the straps including the leash strap may have
the same color or of contrasting colors. Or the straps may exhibit
multi-colored decorative patterns.
Second Embodiment
This embodiment, illustrated in FIGS. 7 and 8, is a highly simplified and
inexpensive version of the first embodiment and may therefore be
manufactured at low cost.
In the second embodiment, the shoulder junction of the harness which
overlies the dog's shoulder between the left and right forelegs takes the
form of a metal D ring 30 having an opening therein banked by left and
right arms. The chest junction which lies adjacent the chest of the dog
intermediate the left and right foreleg crotches is formed by a short
fabric strap 31 having secured to its opposite ends left and right metal
coupling rings 32 and 33 similar to the D ring forming the shoulder
junction.
Secured to and extending between the left arm of the shoulder junction ring
30 and the left coupling ring 32 of the shoulder junction is a fabric
strap 34 provided with a tri-slide 35 adjusting the length of the strap to
a length appropriate to the size of the harnessed dog. Secured to and
extending between the right arm of the shoulder junction ring 30 and the
right coupling ring 33 of the chest junction is a fabric strap 36 provided
with a tri-slide 37 for adjusting the length of this strap. When the
harness is installed, straps 34 and 30 then lie against opposite sides of
the dog, with the head of the dog being received in the open region
between the straps whereby the harness is conformed to the body of the
dog.
A long braided fabric cable is folded in half, a link L being placed in the
cable at its fold. Coupled to link L is the retractable clasp 13 which
terminates the leading end of leash 14, as in the first embodiment.
The folded cable defines left and right restraint cables 38 and 39. The
leading end of left restraint cable 38 is secured to left coupling ring 32
of chest junction 31 and passes through the left foreleg crotch of the
dog, and then through the opening in the shoulder junction ring 30 to
terminate in link L. The leading end of right restraint cable 39 is
secured to right coupling ring 33 of the chest junction and passes through
the right foreleg crotch of the dog and then through the opening in
shoulder junction righ 30 to terminate in link L.
The left and right restraint cables 38 and 39 in the sections thereof
between link L and shoulder junction ring 30 are clamped together by a
retractable clamp 40.
The position of the clamp along the left and right restraint cables
sections is adjusted to provide restraint cables of an effective length
appropriate to the size of the dog. Also provided, as on the first
embodiment, are left and right protective sleeves 41 and 42.
In operation, when the leash is pulled by its holder to control the dog,
this action causes the restraint cables to ride up the foreleg crotches to
engage the sensitive foreleg pits to induce the dog to relieve the
pressure on the pits by slowing down or coming to a halt. Thus a strong
tug on the leash will cause the dog to come to an immediate halt.
While there have been shown preferred embodiments of the invention, it is
to be understood that many changes may be made thereon within the spirit
of the invention.
