They are changing that way of thought. In Europe they usually do a ovariectomy and that is changing here in the USA. With the ovaries gone, the hormones are gone and the chances of getting cancer of the uterus is gone too. This info was in several of the medical pieces and studies done, I have searched for on the internet in the past several months. The ovariectomy is a lot less strenuous on the dog too and may help in urinary incontinence. Thanks, David |
