The gender difference between male and female puppies is not very obvious, but there are still some characteristics that can be used to judge.
Generally speaking, male dogs are usually slightly larger and heavier than female puppies of the same age. But this is only a high probability situation, and it depends on the dog breed, individual and other factors.
In addition, the gender of the puppy can also be determined by the external genitalia. The scrotum and penis of a male dog are more obvious, and the penis is more prominent, while the vagina of a female dog is smaller and hidden in the lower abdomen, making it difficult to detect.
Of course, it may be difficult for untrained people to accurately identify the gender of puppies. The best way is to ask a veterinarian or pet breeding professional to make a judgment.
