Hi there! First, it’s great that you’re being attentive to your dog’s health. When a female dog is in heat, it is actually normal for the discharge to be dark brown, especially towards the beginning and end of her cycle. This happens because the blood is older and has had time to oxidize, changing the color.
What you want to keep an eye on are any significant changes or signs of trouble, such as:
- Excessive bleeding or a sudden increase in the amount of discharge
- A foul odor or pus-like discharge, which could indicate an infection
- Your dog acting very lethargic, vomiting, or showing signs of pain or discomfort
If you notice any of these symptoms, or if the discharge persists longer than a few weeks without tapering off, it would be wise to get in touch with a vet.
In the meantime, you can do a few things at home:
- Keep her clean by gently washing the area with warm water and a pet-safe washcloth as necessary
- Offer plenty of water to ensure she stays hydrated
- Monitor her closely for any changes in behavior or appetite
If at any point your dog seems in distress or you’re just unsure, don’t hesitate to reach out for professional help. Better safe than sorry!
If you're unsure or your pet’s symptoms worsen, it's best to book a call with a vet on Dial A Vet for professional advice.
