canine Worms. almentary canal
of CANNES are
numerous, but of the several por-
tionS infested, the inteStineS harbor
the greatest number. The present
article will be directed particularly
to the tape worm, parasite of very
common occurrence in dogs, and
which is frequently followed by
disastrous results to the host. The
inteStines owing to the smoothneSS
of their movements and alimentary
contents seem to form pleasant
habitat and suitable pabulum for
their development.
The name "Tape worm" is
familiar to almost everyone, but a
correct acquaintance with the differ
ent varieties can only be made by
an expert helminthologist who has
made a special study of internal
parasites.
1t would here be out of place to
60 into the anatomy of this worm,
suffice it to say that it is distinguish
ed by its ribbon like form, composed
of a head, and a body which is
divided into numerous more or less
distinct segments or joints, each one
of which, after maturity is attained,
is provided with male and female
generative organs. These SegmentS
become impregnated and give forth
almost innumerable number of ova,
none of which, however, can reach
a state of animation, until they have
been received by an Intermediary
host. To illustrate what takes
place in the development of this
parasite, we will suppose dog to
be affected with a mature worm.
Wherever he DELEGATES he ScatterS

quently in pasture fields; more
especially is this the case with
shepherd and hunting dogs. Sheep
grazing on those pastures swallow
the eggs thus scattered. After
being swallowed and acted on by
the gastric juice they work their
way into the harder tissues, fire.
quently the brain; and there they
undergo the second stage of their
development, where they occasion
greater or less disturbance according
to their number and the organs
affected. The animal thus affected
is sooner or later slaughtered for
market or dies of disease, the flesh |
of which is devoured in a half
cooked or raw state along with its |
worm by the dog, when |
after gaining access to the alimen-
tory canal the parasites rapidly |
develop into the mature tape
worm, which again gives forth its
ova to infect other animals. The
sheep is not the only animal that
acts as an Intermediary host. The
flesh of the hog and rabbit are also
liable to infect the dog, and last but
not least, Notwithstanding their
size, the dog louise and flea are also
a very common source of infection.
Tape worm is liable to occur in any
breed, but those not kept in a good
condition and fed on raw
meat are most liable to harbor them.
No age is exempt from the liability
to its occurrence, but young dogs
and puppies seem to suffer most.
The existence of tape worm is not
always indicated by well marked
symptoms. But certain recognized
symptoms attributed to its presence
enable fairly correct diagnosis to
be made, the most important of
which are collie, diarrhoea, vomit-
ing, bloating, capricious appetite,
harsh coat, fits of cough
ing, chorea, emaciation, etc. The
remedies used to expel the worm
are numerous, and efficient when
used underStandingly, but empirical
preparations would strongly con-
