The big news lately has been studies on theÂ detrimental effects of spaying and neutering our dogs.Â Â This is actually not anything new but I am so glad it is all coming to light.Â Â You see,Â spaying and neutering can be one of the most detrimental things we can do to the health of the dog (or cat…or even a person!)
I invite you to do some research on your own and come to your own conclusions on this very touchy subject, there is a lot out there on the net and here are just a few things for you to read and look into on the subject.
Veterinary studies done in 2005 (with mostly Rottweilers) showed that dogs that are spayed or neutered have a MUCH higher rate of bone cancer than un-spayed/un-neutered dogs or those spayed late in life. http://cebp.aacrjournals.org/cgi/content/full/11/11/1434
Veterinary oncologist Kevin HahnÂ published an article in Veterinary Practice News entitled “Can We Neuter Cancer In Dogs?”Â August 2005 (Vol 17 #8) p21. (8/14/05) lilibeth.Â Â He opens the artilce by stating that, after reviewing studies reported over the last 30 years, he’s not sure what to recommend to his clients. Like most veterinarians, Dr Hahn mentions the higher incidence of testicular and mammary cancer in intact animals, but also notes that spayed females have a 4 times greater risk of cardiac hemangiosarcomas, and neutered males also show a significant increased risk for this cancer compared to intact ones.
Another cancer Dr Hahn discusses that deserves mention is prostate cancer because a lot of people erroneously believe that castration prevents this. In reality, it does not. In fact, castrated dogs have up to a 4 times greater risk of developing prostate cancer than intact animals. At the same time, spayed or neutered dogs have a 1.5 to 3 times greater chance of developing bladder cancer. Because of this, rectal examinations and abdominal palpation should always be part of a routine veterinary physical examination.
Now another study was recently released:
