In this case the dog acts as q mechanical

Hydatid disease is caused by the pres

and other organs, Of a bladder worm or
Iarv.l tapeworm. Bladder worms are
often as large as an orange and may be
larger. A dog which IL allowed to feed
on carrion or tho raw viscera OF slaugn-
tered animals may eat all or part OF
bladder worm containing numerous tape
worm heads. These tapeworm heads de-
yelop into small segmented tapeworms
in the intestines of the dog. The tape
worms In turn develop eggs whicn are
passed out in the excrement OF the oos;
They are spread broadcast on grass anu
