Can a Dog with von Willebrand’s Disease Be Spayed Safely?
Can a dog with von Willebrand’s Disease be spayed? Yes, with proper preparation and precautions, a dog with von Willebrand’s Disease can be spayed safely. Careful pre-operative testing, specific surgical techniques, and post-operative monitoring are crucial to minimize bleeding risks.
Understanding von Willebrand’s Disease in Dogs
von Willebrand’s Disease (vWD) is the most common inherited bleeding disorder in dogs, affecting their ability to clot blood effectively. The disease is characterized by a deficiency or abnormality in von Willebrand factor (vWF), a protein essential for platelet adhesion and blood clot formation. This deficiency can lead to prolonged bleeding after injuries or surgical procedures.
Diagnosis is Key Before Spaying
Before considering spaying a dog, particularly one suspected of having vWD, accurate diagnosis is crucial. Diagnosis involves a blood test that measures vWF levels.
- vWF Antigen Assay: Measures the amount of vWF present in the blood.
- Genetic Testing: Can identify specific genetic mutations associated with vWD.
- Buccal Mucosal Bleeding Time (BMBT): Assesses how quickly bleeding stops after a small incision in the mouth.
A veterinarian specializing in internal medicine or a veterinary hematologist is best suited to interpret these tests and provide an accurate diagnosis.
Benefits of Spaying a Dog with von Willebrand’s Disease
Despite the risks associated with surgery in dogs with bleeding disorders, spaying offers significant health benefits. These benefits may outweigh the risks when proper precautions are taken.
- Eliminates the risk of uterine infections (pyometra).
- Reduces the risk of mammary cancer.
- Prevents unwanted pregnancies.
- Eliminates heat cycles, reducing behavioral issues.
The Spaying Procedure: Minimizing Bleeding Risks
The spaying procedure (ovariohysterectomy) in a dog with vWD requires meticulous surgical technique and careful monitoring. A veterinary surgeon experienced in handling patients with bleeding disorders should perform the surgery.
- Pre-Operative Preparation:
- Desmopressin (DDAVP) administration: This medication can temporarily increase vWF levels and improve clotting ability before surgery. The veterinarian determines the appropriate dosage and timing.
- Fresh Frozen Plasma (FFP) transfusion: May be necessary in severe cases to provide additional clotting factors.
- Surgical Techniques:
- Meticulous tissue handling to minimize trauma and bleeding.
- Cauterization of blood vessels to stop bleeding effectively.
- Use of surgical staples or sutures for secure vessel ligation.
- Post-Operative Care:
- Close monitoring for signs of bleeding (e.g., pale gums, lethargy, swelling at the incision site).
- Pain management with appropriate medications.
- Restricted activity to prevent disruption of the surgical site.
- Regular monitoring of vWF levels post-surgery to ensure adequate clotting ability.
Common Mistakes to Avoid
Several pitfalls can increase the risk of complications during and after spaying a dog with vWD. Avoiding these mistakes is paramount for a successful outcome.
- Failure to diagnose vWD prior to surgery.
- Inadequate pre-operative preparation, such as omitting DDAVP or FFP when indicated.
- Lack of experience in handling patients with bleeding disorders by the surgical team.
- Aggressive surgical techniques that cause excessive tissue trauma.
- Insufficient post-operative monitoring for bleeding complications.
Alternative Sterilization Procedures
While ovariohysterectomy (spaying) is the standard procedure, alternative techniques can sometimes be considered to minimize bleeding risks, though they are less commonly performed in dogs.
- Ovariectomy: Removal of only the ovaries, leaving the uterus intact. This may reduce the amount of bleeding compared to ovariohysterectomy. However, it doesn’t eliminate the risk of uterine infections.
- Laparoscopic Spaying: Minimally invasive technique that uses small incisions and a camera to perform the surgery. This can result in less tissue trauma and potentially less bleeding. However, it still carries bleeding risks in dogs with vWD.
The suitability of these alternatives should be discussed with a veterinarian experienced in both standard and minimally invasive surgical techniques.
Is Spaying Even Possible? Weighing the Risks and Benefits
Can a dog with von Willebrand be spayed? While it is possible, it’s essential to carefully weigh the risks and benefits. Spaying can prevent serious health problems, but the risk of bleeding complications must be addressed. The decision should be made in consultation with a veterinarian who is knowledgeable about vWD and experienced in surgical procedures in affected animals.

Frequently Asked Questions
Can a dog with von Willebrand be spayed without any risk?
No, there is always some risk associated with any surgical procedure, especially in dogs with von Willebrand’s Disease. However, with proper preparation and a skilled surgical team, the risk can be minimized.
What is Desmopressin (DDAVP) and how does it help?
Desmopressin, or DDAVP, is a synthetic hormone that temporarily increases the levels of von Willebrand factor in the blood. This helps improve clotting ability before and during surgery, reducing the risk of excessive bleeding.
How soon before surgery should DDAVP be administered?
The timing of DDAVP administration varies depending on the specific protocol used by the veterinarian. Generally, it is administered about 30 to 60 minutes before the surgical procedure to allow sufficient time for the vWF levels to rise.
What happens if a dog with vWD bleeds excessively after being spayed?
Excessive bleeding requires immediate veterinary attention. Treatment may include blood transfusions, administration of clotting factors (such as fresh frozen plasma), and medications to promote clotting. Careful monitoring of vital signs is crucial.
Are there any breeds more prone to von Willebrand’s Disease?
Yes, some breeds are more predisposed to vWD than others, including Doberman Pinschers, Scottish Terriers, Shetland Sheepdogs, and Standard Poodles. However, it can occur in any breed.
How is von Willebrand’s Disease inherited?
vWD is typically inherited as an autosomal recessive trait, meaning that an animal must inherit two copies of the mutated gene (one from each parent) to be affected. Carriers have one copy of the gene and usually do not show symptoms, but they can pass the gene on to their offspring.
Is there a cure for von Willebrand’s Disease?
Unfortunately, there is no cure for vWD. Treatment focuses on managing the symptoms and preventing excessive bleeding during surgical procedures or injuries.
What are the long-term considerations for a spayed dog with vWD?
Even after a successful spay, a dog with vWD requires ongoing monitoring and management. Owners should inform their veterinarian about the dog’s condition before any future procedures or treatments. They should also be prepared to manage any bleeding episodes that may occur due to injuries.
Can a dog with vWD have a normal lifespan?
With proper management and care, a dog with vWD can live a relatively normal lifespan. However, it is crucial to be vigilant about preventing injuries and managing bleeding episodes promptly.
What are the signs of internal bleeding in a dog after spaying?
Signs of internal bleeding include pale gums, lethargy, weakness, abdominal distension, difficulty breathing, and collapse. If any of these signs are observed, immediate veterinary care is essential.
How important is it to find a surgeon experienced in vWD patients?
Finding a surgeon experienced in handling patients with vWD is extremely important. They will be knowledgeable about the specific challenges associated with the condition and will be able to take appropriate precautions to minimize the risk of bleeding complications.
What is the cost of spaying a dog with vWD compared to a healthy dog?
Spaying a dog with vWD typically costs more than spaying a healthy dog due to the additional pre-operative testing, medications (such as DDAVP), and the increased risk of complications requiring extended monitoring or transfusions. Consult with your veterinarian for an estimate.
