Neutering is the primary method of sterilizing male pets. It is as important to neuter male pets as it is to spay female pets, even though male pets don't give birth. While a female dog or cat can have only one litter at a time, male animals can impregnate many females each day. Veterinarians perform spay and neuter surgeries under general anesthetic. Animals usually return to normal activity within 24 to 72 hours.
Any discomfort is minimal and well outweighs the suffering and death caused by uncurbed breeding.
Having the surgery also eliminates the risk of certain diseases such as mammary and testicular cancer. Pets should not gain weight after spaying or neutering as long as you provide a balanced diet and encourage regular exercise. The latest medical findings indicate that your pet, male or female, will be healthier and live a longer life if it is spayed or neutered.
