Pyometra in Dogs
Pyometra is a bacterial infection of the uterus that can be life-threatening if left untreated. It occurs when the cervix opens, allowing bacteria to enter the uterus, where they multiply and cause a buildup of pus.
Dogs that are intact (not spayed) and have not been bred are more likely to develop pyometra. The risk increases with age, especially after a dog's heat cycle.
Common symptoms include:
- Vaginal discharge (yellow, green, or red)
- Increased thirst and urination
- Lethargy
- Loss of appetite
- Vomiting
- Abdominal distension
- Fever
Surgical removal of the infected uterus (spaying) is usually the recommended treatment. In some cases, stabilization with fluids and antibiotics may be necessary before surgery.
*Prevention*
The most effective way to prevent pyometra is to spay your dog. If you're not planning to breed your dog, spaying can significantly reduce the risk of pyometra and other reproductive health issues.
If you suspect your dog has pyometra, it's crucial to seek veterinary attention promptly. Early diagnosis and treatment can improve your dog's chances of recovery.
