While dogs do bleed during estrus, the discharge is typically not particularly smelly. It can have a slightly bloody or musky odor, but it's not usually strong or unpleasant.
However, if you notice a strong, foul odor coming from your dog's vulva, it's important to take her to the vet. This could be a sign of a bacterial or yeast infection, which can be treated with medication.
Here are some key points to remember:
* Estrus discharge isn't typically strong-smelling.
* A strong, foul odor could indicate an infection.
* If you're concerned about your dog's health, consult a vet.
