Question I have a two year old, female Rottweiller mix, that is not fixed yet. She is a sweet, obedient animal, and I am concerned about the behavioral changes that occur when an animal has its sexual organs removed. What are the effects on their health and temperament after surgery?

Answer There are no predictable behavior changes in the female dog or cat after ovariohysterectomy. Male dogs, however, often become less dominant and aggressive with other dogs and roam less after neutering. Male cats generally do less territorial fighting and roam less, which dramatically increases their life span.

There are many solid health reasons for spaying and neutering our pets. Early spaying prevents mammary cancer and a uterine disease called pyometra. Both of these conditions can be fatal in the female dog. Neutering male dogs reduces the incidence of prostate and testicular disease.

Preventing unwanted litters is another common reason veterinarians recommend spaying both cats and dogs at six to 12 months of age, preferably before the first heat.

Keeping our pets at home and healthy will provide longer and more pleasurable companionship!
