THE DOG AS A CARRIER OP PARASITES AND DISEASE. 25 
parasitologists have been insisting that the dog is so largely respon- 
sible for the spread and so essential to the existence of so many im- 
portant parasites that we must curtail his liberty and guard him, 
ourselves, our families, and our stock from the evil results of his 
unrestrained wanderings. 
For a number of years public-health officers and others who have 
the welfare of the community at heart have been insisting on a re- 
striction of the dog's unwarranted liberty in order to lessen and in 
time to eliminate the terrible menace of rabies. 
More recently the sheepmen who have been accustomed to keeping 
out of business in localities where there were too many dogs, or who 
have permitted themselves to be forced out of business as a result of 
the attacks of sheep -killing dogs and the resentment and antagonism 
of the dogs' owners, have been taking more aggressive action and 
have started a propaganda looking toward the elimination of the 
worthless dog and the placing of full responsibility for other dogs 
on their owners. 
It is to be hoped that the coordinate action of these persons and 
others interested in the safeguarding of life, health, and property 
will soon bring about positive and valuable results. 
In a general way there are three kinds of dogs — the vagrant, 
ownerless stray ; the other person's dog ; and your own dog. 
The stray dog which recognizes no owner must be eliminated. The 
irresponsible dog with no owner to care for him, to look after his 
health as it concerns the dog and other animals and man, and to re- 
strain him and stand sponsor for his acts and especially the damage 
he may do — such a dog does not fit into a scheme of civilization which 
is based on law and the responsibility of individuals for themselves 
and others. 
We have a right to insist, and should insist, that the other person's 
dog keep off our premises. A dog that is allowed by the owner to 
wander at large will have substantially the same habits of life, the 
same sort of food, and be substantially as dangerous as the ownerless 
dog. Such a dog is not only a trespasser but a potential menace whose 
visits may incur loss of money, health, or even life. 
Your own dog should be handled in such a way as best to further 
the welfare of the dog and the community. He should be kept in 
restraint and not allowed the full freedom of the house or even of 
the outside premises. He should not be allowed to be familiar with 
people, and especially with children. The dog should be kept free 
from external parasites by frequent baths and, if necessary, other 
appropriate measures, and should be freed from internal parasites by 
suitable measures and kept free by adequate attention to his food. He 
should only be allowed to leave the yard or the kennels in company
