* Genitalia are underdeveloped: At that age, the puppy's genitalia are still developing, and it's difficult to distinguish between male and female.
* Similar appearance: Male and female puppies often look very similar at this age, with no obvious differences in their external appearance.
The best way to determine your puppy's sex is:
1. Contact your veterinarian: Your vet can easily determine the sex of your puppy through a quick physical examination. They will check for the presence of testicles in males and the vulva in females.
2. Check the microchip paperwork: If your puppy was microchipped at the breeder, the paperwork should indicate the sex.
Please note: Attempting to determine the sex yourself could be stressful for the puppy and potentially lead to incorrect identification. It's always best to rely on a professional for this.
