The Disadvantages of Not Neutering or Spaying Your Animals


Animals have a natural instinct to mate. At certain times of the year dogs and cats come into season and their aim is to make babies. Many people believe that their dog or cat will not get pregnant as they never go out, believe me when your female is ready to mate she will find a way to escape. [I have a friend who has a 14 year old Terrier that never goes out unless with the Owner and she has just had 3 pups!!!!!] Also if your male smells a female on heat in the neighbourhood they will swim rivers, scale walls, and if necessary climb down steep mountains for 5 minutes of mating.

Neutering is the surgical removal of the reproductive organs of a pet. This includes the ovaries and uterus in the female (spaying) or the testicles in the male (castration, neutering). Veterinarians send most pets home from the hospital the same day after surgery. Pets resume normal activity within a day or two.

What are the advantages?

  • Prevents messy spotting of blood in female dogs and urine spraying in female cats during heat periods
  • Prevents females from attracting groups of male strays while in heat
  • Decreases the male's urge to spray urine to mark territory and to fight over females in heat
  • Decreases embarrassing inappropriate mounting behaviour in male pets.
  • Reduces or eliminates male fighting, irritable aggression of females in heat, and dominance aggression.
  • Reduces tendency to roam or try to escape, thus reducing your pet's chances of becoming lost or injured.
  • When spayed, females are not susceptible to life- threatening reproductive tract tumours, infection of the uterus, and complications from pregnancy. Female dogs who are spayed prior to their first heat cycle (which usually occurs between 6 and 9 months of age) have a significantly reduced chance of developing mammary (breast) cancer compared to dogs who have had even one heat cycle. Spayed females can't develop pyometra, an infection of the uterus that can be quite severe and can even result in death.  Spayed females tend to have more even temperaments and do not go through the hormone-induced mood swings that intact bitches sometimes have. The incidence of breast tumours (which occur in over half of un-spayed female dogs) is less than 1% in dogs spayed prior to the first heat.
  • Neutered dogs often are better behaved than their intact counterparts. Not only are they less likely to roam (visiting neighborhood females is a major reason for roaming), they are also less likely to mark their territory by urinating in the house (testosterone is one of the major drives for this dominance-related activity). In addition, neutered male dogs are much less likely to be aggressive toward other male dogs. These behavior benefits are particularly true if you castrate your dog between the ages of 9 and 12 months, before he becomes sexually mature and develops bad habits.
  • Neutering prevents the development of prostate problems often seen in older dogs. A neutered dog won't develop testicular cancer, a common cancer of older, intact male dogs. Prevents enlarged prostate (occurs in 60% of older dogs); prostate tumours and infections; and perineal hernias and tumours in males.

It cannot be stressed enough that an un-neutered animal is at risk from many life threatening diseases. Please neuter your animal and prevent unwanted puppies and kittens and unwanted health issues is your treasured pet, that could be fatal.
