Pyometra is a high-severity urinary condition that can affect dogs of all ages and breeds. Pyometra is a life-threatening bacterial infection of the uterus in intact female dogs, most commonly occurring 4-8 weeks after a season. Open pyometra (draining discharge) is less immediately dangerous than closed pyometra (no drainage). It is documented across 1 breed, though prevalence and severity can differ significantly between them. It typically becomes apparent at 5-10 years. Early signs to watch for include vaginal discharge (open type), lethargy and depression, increased thirst and urination, and vomiting. When treatment is required, costs are estimated at £1,500-£4,000 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.

Signs & Symptoms

The following symptoms are commonly associated with Pyometra in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.

• Vaginal discharge (open type)
• Lethargy and depression
• Increased thirst and urination
• Vomiting
• Abdominal distension
• Collapse in septic shock

Treatment Overview

Emergency ovariohysterectomy (spay) is the treatment of choice and is curative. Medical management with prostaglandins and antibiotics carries higher mortality and recurrence risk and is reserved for valuable breeding bitches.

Typical onset: 5-10 years

Prevention & Screening

While not all cases of Pyometra can be prevented, the following steps reduce risk or enable earlier intervention:

• Spaying is preventive
• Do not use progesterone-based drugs or allow multiple oestrous cycles without breeding in predisposed bitches
