What age should a dog be spayed 2020?

Given the significant occurrence of joint disorders in males neutered at <6 mo., the suggested guideline for males is neutering beyond 6 months. For females, given the increased risks of joint disorders with spaying through 11 months of age, the suggested guideline is delaying spaying until beyond a year of age.

Do female dogs change after being spayed?

When a dog enters heat, the hormones in her body change. This fluctuation can cause some dogs to become irritable or stressed, and may cause her to act out. Once a female is spayed, behavior tends to be more level and consistent. An unspayed female dog’s hormones may also cause her to display guarding behavior.
