A few hours before surgery
The office called me at home, “Dr. Funk – we have new patient here, a really friendly English Bulldog named Miss Muffin, who may need urgent surgery. The pet parents are working hard to find her help – Miss Muffin’s condition can’t wait until next week – are you available to come in this weekend?” It’s not that simple as I need an emergency team to come in with me for the surgery, but my Oath Animal Team circled the wagons. We were lucky we were able to coordinate a surgery team on very short notice to help.
Time of surgery
“What are you doing here?!” the regular Saturday team asked. I told them I was here to help a pet and my emergency technician was setting up the Operating Room as we speak. The unique feeling of ‘doing surgery when you don’t usually do surgery’ was only overshadowed by the task at hand – remove Miss Muffin’s severely infected uterus before she goes septic. A good surgery was only the first step to success.
Recheck two weeks later
Miss Muffin had recovered without complications, her incision healed beautifully, and her true personality flourished. I had only seen her sick and infected so seeing her happy, playful, and pain-free was delightful. You couldn’t tell she has a life-saving surgery only days beforehand!
If the infection in her uterus spread, she could have become septic and could have died. One can imagine just how painful that must be and how that would make anyone feel!
Dog owners aim to provide the best possible life for their pets through good health and longevity. Intact female dogs face a significant yet avoidable health threat known as pyometra. Recognizing the severity of this disease along with the necessity of spaying your dog can save her life.
Unspayed female dogs can develop pyometra – a dangerous uterine infection that can lead to death. The condition arises from hormonal changes after a female dog’s heat cycle which causes bacteria and pus to build up inside the uterus. Untreated pyometra develops rapidly and it poses a risk of causing sepsis or kidney failure and can lead to death. Common signs include, but are not limited to:
- Lethargy
- Loss of appetite
- Increased thirst and urination
- Vomiting
- Abdominal swelling
- Fever
- Foul-smelling vaginal discharge (in open pyometra)
Pyometra develops quickly which necessitates immediate veterinary treatment, making the condition significant and dangerous. Without treatment the infection will enter the bloodstream which results in septic shock followed by organ failure and death.
The best way to treat pyometra is to perform immediate surgical removal of the infected uterus through an ovariohysterectomy (spay). Surgical procedures on ill animals present higher risks compared to standard spays – internal blood vessels are more friable translating to bleeding being more likely and more difficult to stop. If not extremely careful, the infected uterine contents can spill into – and contaminate – the abdomen, leading to ongoing infection.
The only way to guarantee prevention of pyometra is through spaying which involves the surgical removal of the ovaries and uterus. By spaying your dog you stop the hormonal changes that lead to pyometra development and protect your pet from this dangerous condition. The surgical procedure of spaying also lowers the threat of mammary tumors while eliminating the potential for uterine cancer and stopping unexpected pregnancies. Breed and size dictate the optimal time to spay dogs is between 6 and 18 months of age and coordinated at least 6-8 weeks after any estrus (heat) cycle occurs. Consistent with the phrase, better late than never, spaying older dogs remains beneficial because it continues to reduce their risk of developing pyometra and other reproductive-related diseases.
Dog owners need to know about pyometra since it is a dangerous and life-threatening condition that can generally be prevented. Spaying your dog protects her long-term health and well-being. If there are no plans to show or breed your female dog, please schedule a consult with Oath Animal Hospital to explore treatment options and create a plan. Taking proactive steps today will help maintain your pet’s health, avoid a painful, life-threatening potential, and keep her happy throughout her life.
