A dog cannot get pregnant when not in heat. The heat cycle, or estrus, is the only time during which a female dog is fertile and can conceive. Outside of this cycle, the chances of pregnancy are virtually non-existent. However, some dogs can experience a "silent heat" where they show no visible signs of being in heat, such as bleeding, but hormonal changes are taking place. Even in silent heat, while it may be difficult to recognize, the dog can still be fertile. In summary:
- A female dog can only become pregnant during her heat cycle (estrus).
- During silent heat, she may be fertile without showing typical signs.
- Pregnancy outside of the heat cycle does not occur.
If you suspect your dog might be in silent heat or want to confirm her fertility status, it is best to consult a veterinarian who can perform hormonal tests.
