354 KENNEL DISEASES. 
ble can properly be again alluded to, since it is through the drinking-water 
that a very large proportion of cases of infection occurs. It is a fact, also, that 
many sources of supply contain the ova of worms. 
Where one or only a very few dogs are kept it is quite a common custom 
for them to accompany their owners when marketing, and in butchers’ shops 
they get many bits of meat trimmings. Not a few others are admitted to abat- 
toirs, or are able to obtain more or less of the refuse from such. 
Tt is safe to say that were all meats fed to dogs invariably well cooked, the 
number infested with tape-worms must be small indeed, comparatively. 
Cleanliness in the dog and in his surroundings, as previously said, is one 
very important means of prevention. Nor ought it be necessary to urge that 
in all instances in which treatment for worms is applied, also where there is 
good reason for suspecting the presence of these noxious intruders, every dis- 
charge from the bowels should be burned, and the coat be disinfected often, by 
means of powdered sulphur, rubbed into it thoroughly and in very generous 
quantities. 
The fact should be in sight always that worm medicines, also the purga- 
tives which must generally follow them, are more or less weakening. Strong, 
healthy and robust dogs bear them well, but delicate subjects often require 
supportive treatment for a time; that is, a more generous diet, and likely a 
tonic.
