- Breast
cancer - a female dog spayed before her first heat will have almost a
zero chance of getting breast cancer. After her first heat the chance
is 7%, and after her third heat the chance is 25%! Breast or mammary
cancer can be a fatal disease
- Pyometra - a spayed
female doesn't have any chance to get pyometra, which is a life
threatening condition which generally occurs in middle-aged to older
female dogs 4-6 weeks after heat. A uterus with pyometra severely
engorges and is filled with pus, bacteria, dying tissue, and toxins.
Without prompt treatment, the pet will die. The only way to save her
life would be an emergency spay to remove the infected uterus.
- Convenience
- an adult female dog comes into heat every 6-8 months. It's hard to
keep male dogs away, and bloody vaginal discharge is unpleasant in your
living room.
There
shouldn't be any drastic changes in behavior since the female
reproductive tract is dormant for most of the year.
An
incision is made on the midline of the abdomen, and the ligaments and
blood vessels which hold the uterus and ovaries in place are tied off
with dissolvable sutures and cut. The abdomen is checked for bleeding
and sutures are placed to close the abdominal wall. Another layer of
sutures is placed to close the skin. We use buried dissolvable suture
material.
The
incision is often slightly red and swollen in the first few days after
surgery. It has to be monitored for signs of infection and pain. I
usually send all my female patients home with painkillers after the
procedure to keep them comfortable. It is best to restrict the dog from
boisterous activity, and going up and down stairs. Some owners report
that their pets seem to have troubles urinating and/or defecating right
after the surgery which is explained by the skin tension of the
abdomen.
The
traditional age for spaying is around 6 months of age, but can be done
as early as 8 weeks. To obtain the maximum health benefits it's best to
spay before first heat.
Activity
level and appetite do not change with spaying. A female dog should not
gain weight or become less interested in activity post spay. |
