When entrepreneurs used his invention to play music, Edison thought it was a debasement of his idea. Our widespread misunderstanding of inventors as setting out to solve society's problems causes us to say that necessity is the mother of invention. Actually, invention is the mother of necessity, by creating needs that we never felt before. (Be honest: did you really feel a need for your Walkman CD player long before it existed?) Far from welcoming solutions to our supposed needs, society's entrenched interests commonly resist inventions.
Medium-size dogs are at the midway point between tiny and massive canines, and both height and weight factor into the classification. Medium-size dogs generally weigh in the ballpark of 35 to 65 pounds, according to Kim Williamson of Animal Planet.. In terms of height, medium-size dogs are usually from 1 to 2 feet tall, measured from the ground to the withers or shoulder.
How much your dog should weigh depends on several factors, for example breed, sex, height and general stature. It is often incorrect to look at the breed average and think this weight is correct for your dog. The correct weight for your dog, is what they weigh when they have a perfect body condition score. A dog at perfect body condition score should have ribs that are EASILY felt (ahem, Cadbury), the lumbar waist should be visible, there should be clear muscle definition, thin fat cover and an abdominal tuck.
