Science Birthdays, August 18

Today is the birthday of Alfred Wallace, born in 1823, like Darwin he sailed off on a ship for scientific exploration. In 1848 he traveled to the Amazon and wrote a book on his travels, the ship burned and many of his records were lost. He collected over 125 000 specimens on a trip in 1854, he drew a line between continents of Asia and Australia called the Wallace Line where organisms were different on each side. He shared publication with Darwin but he was sick with ague and didn’t accept that man could come from animals.

Dog Tip of The Day, August 18

Escape conditioning occurs when the dog hears a sound or some warning that an unpleasant event is about to occur. This type of conditioning sometimes occurs without our intervention. For example, sometimes when the stove is on, it sets off a heat alarm in the kitchen. The dog will leave the kitchen when it sees you turning on the stove, because it wants to escape from the shrill warning of the heat alarm.  This type of conditioning can be put to use in training if an undesirable action is preceded by a sound to let the dog know a correction is coming.  Escape conditioning is like a warning.

Dog Tip of The Day, August 17

Another form of conditioning is escape conditioning. In escape conditioning, something unpleasant, like an ear pinch is used until the dog complies, then the unpleasant stimuli is removed. I am not a fan of this. I always go with the idea, what you do to train a dog should be no different than teaching a child. I wouldn’t want to teach a child by pinching his or her ear.  I stick with the positive training methods.
