The
Truth about Juvenile Spay/Neuter
(reprinted from the Best Friends Animal Sanctuary Resources Section)
When is the right time to spay or neuter puppies and kittens?
By Richard Allen, DVM

Timing is
everything when it comes to spay and neuter. Most people who care about
animals today want to spay or neuter the pets they bring into their home.
But even the best intentions can get waylaid, and if plans to take Fluffy
or Fido in to be fixed are delayed just one day too long, a new litter can
easily result.
That’s
why every organization or person that places animals in new homes must
have them spayed or neutered before adoption. It’s a policy that we
never waiver from here at Best Friends. And it is something that cannot be
left to the new pet owner, no matter what promises they make.
If
animals are routinely spayed or neutered before placement, there’s no
risk factor that they’ll create more puppies and kittens to add to the
throng of unwanted offspring that already exists.
This
policy of “fixing” before adoption requires that I spay or neuter
puppies and kittens as well as adult dogs. Early spay/neuter is surrounded
with loads of myths and misinformation. I am passionate about this issue
and wish to give you the facts so you may share them and spread the word
about this essential procedure.
Lots of articles have been written

When should an
animal be spayed or neutered?
The
answer to this question depends on the situation. If the animal is
available for adoption, the pet should be fixed before the new owner
receives the pet, regardless of the animal’s age. (Clearly animals that
are too young to be spayed or neutered are too young to be adopted!)
If the
animal is already owned, spay/neuter can be incorporated into the shot
series. Fixing the animal when the rabies shot is given works great. Here
at Best Friends, rabies shots are given at 16 weeks.
How young can an
animal be when fixed?
Puppies
and kittens can be spayed very early — as young as four weeks. The goal
here is to get them fixed and ready to go as soon as they are weaned.
I
routinely spay/neuter at six to eight weeks. These surgeries are called
juvenile spay/neuter or early spay/neuter. The procedure is quick and easy
and works great.
Remember
that kitties can go into heat and get pregnant as early as five months of
age, which is a bit like babies having babies. So, a little
procrastination by the new owner can result in undoing all the good we did
adopting the animal in the first place.
Does early
spay/neuter affect the look or health of the pet?
Years of
careful observation have shown that pets that were fixed very young have
lives that are as long and healthy as any other.
Two
considerations that have been studied closely are the way that bones grow
and the differences in body mass of those animals that were fixed early
on. There is very little difference between early altering and later
altering in these pets. Originally, there was some concern about male cats
experiencing potential urinary blockages. Now we know that male cats have
the same chances of urinary blockage with or without early fixing.
Is early
spay/neuter risky or dangerous?
Any
surgery has inherent risks. We try to reduce risks to as close to zero as
possible by knowing our procedure and diligently watching our patients.
Young
animals heal fast and are lower surgical risks than older animals who may
be obese, in heat, pregnant, or ill. Moreover, young animals are more
predictable and wake up faster after anesthesia. Perhaps we were all the
strongest when we were babies.
Why don’t all
veterinarians do early spay/neuter?
I can
only tell you why I didn’t do early spay/neuter in my private practice
before coming to Best Friends. I was afraid to. I had been to a veterinary
school that did not mention early spay/neuter or teach the techniques that
make it a simple, safe, and effective procedure. Moreover, I was not given
the knowledge of the benefits and the lack of harmful side effects.
It is
time for a call to arms amongst all veterinarians against the pet
overpopulation problem in this country. Early spay/neuter is a valuable
tool in this epidemic and all pets are the winners.
