Many new breeders complain that it is difficult to determine the sex of puppies in the first weeks of their life. To know for sure who your future pet is - a boy or a girl, show the baby to the veterinarian. Although it is quite possible to cope on your own using the traditional method of examining puppies.
According to the book How to Choose and Raise a Puppy, as soon as the babies get a little stronger, you can try to determine their gender. To do this, place the puppy in an upright position or turn it over with its tummy up.
Examine the crotch between the hind legs. In the male, the genital organ is located almost on the tummy, and in the bitch, it is located closer to the anus. In appearance, the genital organ of the knot resembles a heart.
When in doubt, look at adult dogs. Babies are all the same. When determining the sex of newborn puppies, do not be too lazy to check the condition of the skin, ears, eyes, coat. If the eyes are watery, and a tick has gotten in the ears, take the puppy to the veterinarian and start treatment immediately.
