The longer you wait,the better!Removing the reproduction organs will cause a hormonal imbalance.Sex hormones (which will no longer be produced) are not only responsible for sexual behavior. They also regulate growth.' In each long bone there is a growth plate, which is a band of cartilage found near the joint. This growth plate lays down bone as a puppy develops and, as it builds bone, the bone becomes longer and the puppy gets larger and taller. Once maturity is reached, this growth plate turns into bone and the puppy’s full height is reached. What would happen if one of those bones underneath the joint stopped growing before the other bone and they ended up being different lengths? It would be very much like building a house on a slope: the weight of the home wouldn’t be evenly distributed and there would be increased load at the lowermost corner of the house.'. So without the hormones produced by the sex organs, your puppy may be at risk of having joint issues later on.
In my opinion 8 months would be the absolut youngest to spay.
There are many studies out there that show the risks of early spaying/neutering.
In some countries it is illegal to spay/neuter an animal if not cause by a medical emergency.
