Poppy is nearly 6 month old. When would be the best time to have her spayed? She is still kinda small for a standard but much bigger than a mini. Would spaying her now have an effect on her size?
Hip dysplasia is HEREDITARY it is not caused by early spaying or neutering. The people who did this so called "study" used dogs who were not tested for HD and used breeds who are known for bad hips, I believe it was Airedales.This is just me, but w/ a standard I would wait longer. There have been studies (I'm sure you can find them w/ google) linking early spay/neuter w/ HD.
HD is not always hereditary and can be caused by strenuous activity at a young age or injury. It makes sense to me that if early spay/neuter can affect the way a dog structurally matures, it could be linked to(I never said cause) HD. I'm not saying any study is gospel, only that they're worth looking at IMO.
