All dogs older than 8 weeks, weigh at least 4 kilos (2 pounds) and are healthy should be sterilised prior to adoption. However, it is important to not let strict adherence to this rule undermine a potentially successful adoption.
If a dog is too unhealthy for surgery, it may be best to hold off finalising any adoption until she has recovered.
Spaying or neutering is unlikely to change a pet’s temperament, basic personality or levels of playfulness and general activity. However, it can reduce the incidence of some behavioural issues, especially sexual behaviors, such as mounting, howling and the urge to roam.
