apparatus to obtain a dog to keep up with the good

摘要

A device for use in the training of a dog, for example to dissuade the dog from barking. The device, which is carried by the collar of the dog, has a tank which carries a substance that affects the special senses of the dog, particularly the nose and the eyes. The tank has a valve which, when activated, releases a spray of the substance in the region of the head of the dog. An electronic circuit is provided to actuate the valve of the tank when desired, for example, in response to a signal from a microphone with a filter which is sensitive to the frequencies that correspond to those of the bark of the dog. The electronic circuit may also be responsive to a signal from a remote transmitter, to permit a trainer to actuate the release of the spray when desired as part of the training of the dog, and a selector switch may be provided to selectively permit the release of the spray either on command from a remote location or automatically in response to the barking of the dog. The special substance in the tank may either be in the form of a pressurized aerosol of the substance, or a pump may be provided to pressurize a normally unpressurized substance at the time of its release.
