STERILISATION OF DOGS IN
Dr Sing Kong Yuen, BVMS (Glasgow), MRCVS
The reasons for neutering the
male dog are:
1. Urine stench in the apartment. Some
mature male dogs spray drops of urine onto the walls and furniture, making
family members angry.
Maltese was beaten by the father but the dog continued to spray urine
inside the apartment. "He had passed a lot of fresh blood in his urine,"
the young lady confirmed that the dog was beaten hard on his kidney area
by her father, many times for "misbehaving". "However, he could not
stop his natural desire to spray urine to mark out his territory".
Neutering of this dog early would have prevented harsh punishment as the
dog would not mark the walls of the apartment.
2. Aggressive biting of children and the care-giver.
Sometimes, the dog is euthanased as they become uncontrollable. The 2
common species of male it bites everyone.
behaviour. Gripping people with both legs as if the dog wants to mate
with the person. This can be traumatic to visitors, especially female
4. Testicular cancer. The probability of the undescended
testicle becoming cancerous is higher than descended ones. Most
owners fail to detect the cancer in the older dog (more than 7 years old).
Testicular tumour (Sertoli)
in an undescended testicle, circum-anal tumours, enlarged prostate,
infected prostate and perineal hernias are more common in the older
non-neutered male dogs. I advise neutering the dog young to prevent such
worries and increased medical costs in resolving such health issues.

Breast cancer if you don't
sterilise your bitch?
"Why don't you tell the owner that the bitch will get breast cancer if
she is not sterilised?" an experienced dog groomer asked me when I went to
his pet shop to vaccinate his puppies for sale in 2004. "You will increase

There is a conflict of interest for a private veterinarian to recommend
spaying to every dog owner as he generates income from surgeries.
In any case, many younger Singaporeans feel that it is un-natural to
sterilise their pets. They are aware of the pros and cons of the surgery
as the internet provides a rich source of information easily.
The main reason Singaporeans
their female dog are:
1. Soiling the apartment. The blood drops from the female dog in heat need
to be cleaned up.
2. The considerably reduced
annual dog licence fee for spayed females is an incentive for spaying.
3. Accidental mating may also
occur if there is a male dog. I have a case of a female Silkie
terrier mated by a Shetland sheepdog in an apartment. She needed Caesarean
4. Prevention of breast cancer and womb infection in the older bitch (more
than 7 years old) when the female dog is spayed at less than one year old.
Is sterilisation safe for
the dog and when to do it?
In 99% of the surgical cases, the normal bitch or dog does not die from
the anaesthesia or surgery. Toa Payoh Vets' recommended time
to sterilise is after 6 months of age for the male and 2 months after the
first bleeding for the female dog if you wish to sterilise them early.
This may mean the male dog is 8 months old and the female dog is 10-12
months old at the time of sterilisation. Consult your vet for his or her

is used during spay. The bitch usually wakes up before the last stitch is
tied. The bitch goes home in the evening. There is no need to return
for stitch removal as the stitches dissolve in 21-30 days.
