Vaginal discharge in dogs

Vaginal discharge in female dogs can be clear, coloured, bloody or pus-like. While discharge during your dog’s season (heat) may be normal, some types of discharge may be associated with serious health issues. Always check with a vet if your dog develops an unexplained vaginal discharge.

Vaginal discharge during a normal season in an unneutered female dog may be bloody, clear or mucus. But discharge can also be a symptom in dogs with vaginitis, urinary tract infections or uterine (womb) infections, particularly where accompanied by other signs, such as excessive rubbing, licking or systemic (general) illness. These conditions may be serious, even life-threatening. Early identification and treatment offer the best outlook for any health concern.
