Spayed female dogs and cats will not develop uterine or ovarian cancer. The risks of breast cancer are greatly reduced if spaying is done before the first estrus cycle, and, of course, the spayed female will escape all the health risks involved in bearing puppies or kittens. Neutered males show a lower incidence of prostate cancer and prostate disorders and are less likely to run away from home in search of females, exposing themselves to dangers of road traffic and fights with competing males. Better Companions Spayed and neutered pets are better, more affectionate companions. As domestic animals, dogs and cats naturally like people, but this natural affection can be outweighed by the drive to reproduce, which can lead to fighting, aggressive behavior, howling, barking, and roaming.
Neutered pets are calmer and more content.
If you have more than one pet, you'll find that neutered pets tend to get along better with one another. Spayed and neutered pets are generally less likely to bite or attack or to develop behavior and temperament problems. Unspayed dogs will attract male dogs for up to 21 days, often twice a year, and similarly, cats, six to seven days, three or more times a year. Females in heat experience a blood flow that can stain your rugs and furniture. They also attract all the neighborhood males to your house.
