Thank you for submitting your question regarding Precious. Spaying removes the risk of uterine cancer or a uterine infection. It decreases the risk of mammary cancer up until the fourth heat cycle. Females rottweilers that are spayed before 1 year of age have an increased risk of osteosarcoma, but that is the only associated that seems credible. I have not seen an increase in hemangiosarcoma in spayed dogs. I hope this information helps!
