FAQ Neutering/Spaying
WHAT ARE THE HEALTH BENEFITS TO THE DOG?
There are several health benefits to neutering. One of the most important
concerns the prostate gland, which under the influence of testosterone
will
gradually enlarge over the course of the dog’s life. In age, it is likely
to become uncomfortable, possibly being large enough to interfere
w/defecation. The prostate under the influence of testosterone is
also predisposed to infection which is almost impossible to clear up without
neutering. Neutering causes the prostate to shrink into insignificance
thus preventing both prostatitis as well as the uncomfortable benign hyperplasia
(enlargement) that occurs with aging. It is often erroneously held
that neutering prevents prostate cancer but this is not true.
Other health benefits of neutering include the prevention of certain types
of hernias and tumors of the testicles and anus. Excessive preputial
discharge
is also reduced by neutering.
WHAT BEHAVIORAL CHANGES CAN BE EXPECTED AFTER NEUTER?
The only behavior changes that are observed after neutering relate to behaviors
influenced by male hormones. Playfulness, friendliness, and
socialization with humans are not changed. The behaviors that change are
far less desirable. The interest in roaming is eliminated in 90%
of neutered
dogs. Aggressive behavior against other male dogs is eliminated in 60%
of neutered dogs. Urine marking is eliminated in 50% of neutered
male dogs.
Inappropriate mounting is eliminated in 70% of neutered dogs.
WHAT EXACTLY IS DONE SURGICALLY?
An incision is made generally just forward from the scrotum. The testicles
are removed through this incision. The stalks are tied off and cut.
Castration is achieved. If the testicles are not removed, the desirable
benefits listed above cannot be achieved. The skin incision may or may
not
have stitches.
WHAT CAN I EXPECT UPON DISCHARGE FROM THE HOSPITAL?
The scrotum is often swollen in the first few days after surgery, leading
some people to wonder if the procedure was really performed. If the dog
is
immature at the time of neutering, the empty scrotum will flatten out as
he grows. If he is mature at the time of neuter, the empty scrotum will
remain
as a flap of skin. Sometimes the incision is mildly bruised but this is
not unduly sore for the dog and pain relief is almost never necessary post
neuter. Most male dogs are eager to play by the day after surgery but,
to keep the incision intact, it is best to restrict the dog from boistrous
activity.
AT WHAT AGE CAN NEUTERING BE PERFORMED?
Neutering can be performed at any age over age 8 weeks. Dogs neutered
before puberty (generally age 6 months) tend to grow a bit bigger than
dogs
neutered after puberty (testosterone is involved in the causing bones
to stop growing so without testosterone the bones stop growing later).
Neutering can also be performed in the geriatric patient should the prostate
gland become enlarged and the best medical decision be to shrink it.
In this
event, preanesthetic bloodwork and other diagnostics relevant to anesthetizing
an older patient would be recommended.
The traditional age for neutering is around 6 months of age and many veterinarians still recommend neutering at this age.
The benefits of neutering (both health and behavioral) can still be obtained
regardless of the age at which neutering is performed.
WILL HE GET OVER-WEIGHT OR LETHARGIC?
Activity level and appetite do not change with neutering. A male
dog should not gain weight or become less interested in activity post neuter.
WILL HE STILL BE INTERESTED IN FEMALES?
His interest will be reduced but if he is around a female dog in heat,
he will become aroused by her. Mounting behavior often has roots
in the
expression of dominance and may be expressed by a neutered male in a variety
of circumstances that are not motivated by sexuality.
WHAT IF A DOG HAS AN UNDESCENDED TESTICLE?
Undescended testicles have an increased tendency to grow tumors over
descended testicles. They may also twist on their stalks and cause
life-threatening inflammation. For these reasons, neutering is recommended
for dogs with undescended testicles. This procedure is more
complicated than a routine neuter; the missing testicle can be under the
skin along the path it should have descended to the scrotum or it may be
inside the abdomen. Some exploration may be needed to find it thus there
is often an incision for each testicle. The retained testicle is sterile
and
under-developed. If there is one descended testicle, this one will be fertile
but since retaining a testicle is a hereditary trait, it is important that
the
male dog not be bred before he is neutered.
