According to most sources, the human hearing (frequency) range is between 20 Hz and 20,000 Hz (bats can hear up to 100,000 Hz!). What does that mean? Sound is a mechanical wave that propagates through a medium (air, water), and the frequency of a sound wave determines its tone and pitch.
A male dog can mate when he's 6 months and older. For females, it's best to wait until they are 2 years old. That way there is less of a chance of miscarrage and she'll have m â¦ ore time to mature and be physically ready for puppies.
They are weaned at 5 to 7 weeks old. Male pups leave the den when they are 6 to 9 months old, females usually stay with the parents and form a pack. Adult size is reached between 9 and 12 months and they can begin mating when they are one year old. Coyotes can mate with domestic dogs and occasionally with gray wolves.
