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

on treatment OF tho ailment. / feel
that the article. as the work of 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 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, z 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-
mia, due to her bloodless state When,
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
found hook worms in quantities, and
later, microscopically. numbers of the
embryo in various states.
Rule to Follow.
"a good rule to follow for the dosage
or this drug would be. after fasting the
dog for twenty-four hours. to give one
drop in hard capsules for each pound
weight OF dog. This need not be fol-
lowed by purgative.
Carbon tetrachlorid will also remove
a. large per cent. of the ascoris or round
worms. In these cases prefer giving
chenopodium with the above in the ratio
OF three to one. or, we will say. to an
adult dog weighing forty-flve pounds
give forty-five drops of carbon tetra-
chiorid and fifteen drops Of chenopodium
In hard W capsules. In this case, how
ever, we follow with dose of castor
OH. repeat In about week. so that
no guilty ones escape. This will eradi-
cate both hook and ascoris. commonIv
known as round worms
1T is we'll to state at this time that
carbon tetrachlorid is of no avail for
the removal of tapeworms. whip worms
or strongylus, species occasionally
round In the heart wall. I am under
lhe 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 % capsules of car
bon tetrachlorid.
I'm looking over a kennel of dogs
you frequently see one which looks thin
and emaciated. The trainer on being
1nterrogated. informs you that the dog
eats moderately. but has no pep and
mas peen 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 I'm thirty days tho
chances are you would fail to recop
nize 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
Impractical 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 a 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.
1T Is generally believed that the para
site not only acts by sucking blood
but that 1t secretes a poison. which.
being constantly injected into the mucous
membrane of the intestine. is respoa-
sible for much OF the damage.
