I'm a vet and NO I don't tell people to spay early because of unwanted dogs! Spaying does not negatively effect growth. Studies have shown that spaying early can result in longer bones, but we're talking millimeters, nothing visible. I will spay/neuter kittens and pups anytime after they are 6 weeks old. At such a young age, they bounce back from surgery SOOOOO incredibly fast. They heal faster and come out of anesthesia quicker and more smooth. The surgery is nearly bloodless in a young puppy or kitten, greatly reducing the risk of bleeding. There are legitimate studies that suggest spaying early can increase the risk of certain cancers, such as osteosarcoma and hemangiosarcoma. but to reduce those risks, the dog would have to be over a year old, and spaying at that age or older INCREASES the risk of other cancers, such as mammary. Spaying prevents pyometra, which can be deadly. The health benefits of early spaying to me, outweigh the risks, especially taking into account that young animals handle the spay/neuter so much better than adults. Some studies say that neutering male dogs decreases the risk of prostate cancer, but other studies say neutering increases that risk. There are a lot of factors involved in weighing the risks and benefits of early alteration, and more research needs to be done on this to really make a decision, because many of the factors are unknown. www.columbusdogconnection.com/Documents/TracyLand%5B1%5D.doc . I work at a spay/neuter clinic, performing 25-30 surgeries per day, so I personally SEE the difference between the younger and the older patients.
