"More than 2 months had
passed," I said. "It will take a very long time for the wound
to heal using daily nursing care and bandaging," I advised a
gentleman who did not want to bring the dog back to the
factory as the factory space is greasy and oily.
This dog was not under my case and so I did not interfere with
the management. Sometimes, the owner has given specific
instructions or wishes to impose his or her own instructions
on how to manage the dog bite wounds owing to economic
considerations. This was not my case as I would have done a
Z-plasty if the owner could permit it, at the start of the
Still, I am very concerned about this dog's welfare since his
wound is in a high tension area and has not granulated after
two months. As each vet treats a case differently according to
his or her judgment and the owner's financial consideration,
it is hard for the vet sometimes to derive an excellent

effective and would be more
costly. Still, I would
strongly advise the Z-plasty
at the start. Due to the

The image above shows one
approach to get the "Z"
SURGICAL APPROACH 2.
Another approach is briefly
as follows. Consider the
wound as a vertical line.
Midpoint between the
vertical line as a reference
guide, use the marker pen to
put a "cross (X)" e.g. 5
inches horizontally to the
right edge of X. Repeat the
procedure horizontally to
the left side of the left
edge of X.
Make a skin incision from X
downwards, to the bottom of
the vertical line for the
right side, creating a
triangular flap. For the
left side, make a skin
incision from X upwards,
creating a triangular flap.
When viewed from the front,
the cuts look like an "N"
unlike the first approach.
Then rotate the two flaps.
The final suture pattern
will be a horizontal line.
In theory, it is easy. In
practice, it is difficult

2 months had passed. I advise that the wound by cauterised
chemically as it would be relatively costly to do the Z-plasty
without a guarantee that the wound will heal normally. This is
because the location of the wound is in a high tension mobile
At the end of the day, much depends on the economics and the
recommendation of the vet. Many older owners in the heartland
practices, in my opinion, are not too keen on surgery and
anaesthesia, due to the higher costs involved and a
no-guarantee of successful outcome as in this case. But
sometimes, it is penny wise, pound foolish. A younger
sophisticated generation may have a different mindset. Still
owner education as the illustration in my images will be
useful. So far, no practising vet has produced veterinary
medical illustrations of common surgeries or that I cannot
find a handy book. The medical doctors do have some books on
specific parts of the anatomy e.g. piles surgery. I guess
there is no income incentive to produce such a book which
could also be expensive to buy. However, the internet does
help a lot to produce surgery educational videos and
