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.
A male dog, (stud) can go through puberty between 5 and 12 months of age. If your dog has not reached sexual maturity by 12 months, talk to your vet. The age varies by breed with smaller dogs maturing earlier than larger breeds.A male can be sexually viable as early as 5 months.Watch your puppy around females in heat to prevent copulation.KC requires that your dog be less than 12 years old to register a litter. I think that a bitch should be retired by 8 years old at the latest, optimally around 5 years of age. Every dog is different, so you should talk with your vet about your dogsâ health and age. A stud is really never TOO old to copulate.
