I could be totally off about this, and correct me if I am, but from what I read it sounded like if you get them fixed before their growth plates close they may not close quite the way they are supposed to for a while and their bones may continue growing longer but not denser, causing them to be more delicate. I think there was a mention of increased chances of bone cancer with the early spay also.
On the other side it sounded like spaying before the 1st heat took the risk of certain types of reproductive cancers down to barely existent. It sounded to me like the chances were still super low spaying before the 2nd heat too though. |
