According to SPAY USA, an intact female dog, her mate and the resulting offspring (if none were spayed/neutered) add up to 12,288 puppies in 5 years.

When there are too many dogs or cats, animals that are casually acquired run the risk of being casually cared for.

Altered animals live longer, healthier lives. Female cats and dogs have reduced uterine, ovarian, and breast cancers: Male cats and dogs have reduced risks of prostrate cancer and disorders.

Altered animals make better, more affectionate companions.

Neutered cats are less likely to spray and mark territory.

Neutered males are less likely to roam, run away, get hit by cars, get into fights or chase livestock.

Spaying a female dog or cat eliminates the heat cycle. That means no incessant crying, nervous behaviour, or unwanted male dogs lingering around your house.

Spaying or neutering is a humane way of animal control. Many dogs or cats are euthanized daily. Many are tied up and shot. Many die because of disease or starvation
