DISCOVERS SPECIFIC
FOR WORMS IN DOGS
DIR. Sydney J. Smith Tells Of
Experiments With Carbon
Tetrachlorid.
BY FRANK r. DOLE.

Attempts to find some real specific for
worms in dogs are as old as the dog
game itself That malady has been the
bane OF breeders and exhibitors. I read
with great interest an article in the
American Field by DR.. Sydney ]. Smyth
on treatment OF the ailment. / feel
that the article. as the work of a physi-
clan who has devoted much study to
the question, is well worth the attention
Of THE HERALD's kennel readers. 1t fol-
lows
Il have made a number OF expert
ments recently with the use of carbon
tetrachlorid and am firmly OF the belief
that at last we have discovered a specific
Tor the hookworm. This drug possesses
qualities that will at once appeal to dog
lovers OF the South, who annually lose
valuable animals by this scourge.
Recently eight of my bred in the pur-
pie pointer puppies. months of age, be-
came III. One of them died and on post
ing the puppy careful attention was paid
10 all or her thoracic and abdominal
Viscera. Nothing pathologic was discov-
cred except startling condition OF ane-
however, the intestine was opened and
examined the adult hookworm was found
IN large numbers. attached to the bowel
IN their characteristic manner.
The remaining puppies were then
given thirty drops of chemically pure
carbon tetrachlorid and in the stools we
round hook worms in quantities, and
iater, microscopically. numbers of the
embryo in various states.
Rule to Follow.
"A good rule to follow for the dosage
OF this drug would be, after fasting the
dog for twentyfour hours, to give one
drop in hard capsules for each pound
weight of dog. This need not be fol-
lowed by a purgative.
carbon tetrachlorid will also remove
a large per cent. Of the ascoris or round
worms. In these cases I prefer giving
chenopodium with the above in the ratio
OF tnree TO one, or, we will say, to an
aault dog weighing forty-fve pounds
sVe Iorty-nve drops of carbon tetra-
chlorid and fifteen drops Of chenopodilInn
in hard 90 capsules. In this case. how
ever, we follow with a dose of castor
OIL. Repeat in about week, SO that
no guilty ones escape. This will eradi-
cate poth hook and ascoris, commonly
known as round worms.
IL Is well to state at this time that
CARBON tetrachlorid Is of no avail for
the removal of tapeworms, whip worms
or strongylus, q species occasionally
found in the heart wall I am under
the impression that there is not a dog
kennel south OF the Mason and Dixon
line that would not profit by giving
each adult dog two 90 capsules Of car
bon tetrachlorld.
In looking over kennel OF dogs
you frequently see one which looks thin
ana emaciated. The trainer, on being
lhterrogated, informs you that the dog
eats moderately. but has no pep and
mas been treated for round and tape-
worms with no result. This dog. to NV
mind. is an ideal case to give this drug.
ana on return visit in thirty days the
chances are you would fail to recog-
hize the dog. so great the Improvement.
In case you do not find numbers of
the parasite in the stools after this
treatment, be not discouraged, for these
worms are not easily discovered by the
unpracticed eye. and again, some OF
these worms seem to cause much severer
disturbances in one body than I'm others.
since 1t is found that some dogs with
comparatively small infection Of the
parasite suffer much more than those
which harbor considerably greater
number. This must be due either to
some of the worms being more virulent
than others. or to certain dogs being
more susceptible to their disease produc-
ing power.
ut is generally believed that the para
site not only acts by sucking blood
put that IT secretes a poison. which.
being constantly injected into the mucous
membrane of the intestine. is respoa-
sible for much of the damage.
