Know If Your Dog Is Hurting
This product is a bit pricey but it could be invaluable in the right circumstances.
The Pain Gauge is at PetGadgets.com.
The Pain Gauge measures an organism’s electrodermal activity at any given moment by passing a sub-threshold (undetectable) DC current from one electrode to an adjacent second electrode. These small button electrodes are gently touched to a non-fur/hair area of the body such as the bottom of a fingertip/paw, the nose, or even the inner part of an ear. The reading only takes a second.
The device measures the level of pain/stress, which is represented by a numeric LED display ranging from “Calm/No Pain” at 0 to “Tense/Severe Pain” at 9.9. This number is then recorded as the current pain/stress level.
Although each living organism is unique and should have its own baseline readings done when possible, some generalizations can be made. When the pain/stress level number is low, the subject is typically calm and in no pain or distress. When the number increases from this baseline level then some level of pain and/or stress can be concluded. The higher the number, the greater the pain and/or stress. In general, anytime the reading moves to a significantly higher number, e.g., 3 to 6, it can be concluded that pain/stress levels have increased. This analogy also works in the reverse to indicate less pain or stress.
