Direct sequence contrasts with the other spread spectrum process, known as frequency hopping spread spectrum, or frequency hopping code division multiple access (FH-CDMA), in which a broad slice of the bandwidth spectrum is divided into many possible broadcast frequencies.
Puppies are generally ready to eat solid food between the ages of 6 to 8 weeks old. However, according to Purina, it's not uncommon for puppies to start eating from their mother's dish at 4 or 5 weeks old. A puppy attempting to eat adult food does not necessarily mean it's ready to be weaned. The Complete Book of Dog Breeding warns owners that an aggressive appetite is only one sign of maturity.
For example, make a mixture that contains 25% of the new food and 75% of the old food and feed that for several days. Then make it 50-50 for several days, then 75% new food to 25% old food for several days. Then you can start feeding 100% new food.or dogs of any age that eat dry food, water will be needed to rehydrate it in their stomachs for digestion. Puppies also need more water per pound than adults do because they are growing. Growth comes through very active metabolism at the cellular level.
