Hi, I can help you with your question today.
This is a topic of some controversy. In the past, almost every general practitioner would have told you to spay her now. More recently though, we have been seeing more evidence that waiting to spay until after 1 year of age is beneficial in preventing orthopedic issues such as cranial cruciate ligament ruptures
and problems from hip dysplasia.
On the other hand, you do need to endure one heat cycle
before her spay. Also, we do see a slight increase in risk of mammary tumors
in dogs that are spayed after the first heat cycle.
At this time, we are all looking at the new published studies and weighing the risk of mammary tumors with orthopedic problems. Because orthopedic issues are so much more common, at this time, I recommend waiting to spay her until after 1 year of age.
Please let me know if you have further questions. I am happy to continue until I provide the service that you seek.
