Since the earliest childhood the phrase is familiar to us:  "A dog – the friend of the person".  And 
we got used to it and we don't reflect that it means.  And she means 
a lot of things
 For a long time the dog (canis lupus familiaris) lives near us. 
Dogs rescuers help to get out people from under blockages; dogs
guides help to move to people with the weakened sight,
guard dogs (German shepherds, Shar-Peis, etc.) help to protect
various important objects, including Frontier;
hunting dogs (dachshunds, Labradors retrievers and so forth) help to get
game and wild animals; decorative dogs (Pekineses, toy terriers
etc.) please us. During the Great Patriotic War of a dog
pulled out wounded fighters from a battlefield … A lot of things dogs give us love
for that we are, and ask nothing in exchange. And than we answer them?
 I have a question:  "From where there were stray dogs?  " Answer 
on it it is very sad: "They once had an owner, but suddenly they became
are necessary to nobody.  " Little puppies touch us the awkwardness 
and that are extraordinary amusing.  But passes time, puppies grow and 
turn into adult dogs who already are pleasant not to all.  People 
throw out them on the street, as the bothered toy. So we betray friends.
 Homeless animals are doomed to hunger, diseases and death.  Separately 
it is necessary to notice problems of their traumatizing.  Many drivers 
the motor transport which becomes more increasing, at all 
stopping, leave, having brought down a dog or a cat.  The animal remains 
to suffer on the road waiting for the help which doesn't come …  Whom 
then to call "animal":  the person who dooms this being on 
torments, or a stray dog who tormently carries out all the life?
 Vagrant dogs get off in packs and become extremely dangerous. 
Cases of attack of homeless animals on people are frequent. In our town
such animals attacked more than once adults and children.  That it:  protection or 
revenge? This my question remains without answer.
 But I hope that our society started recovering from indifference.  In 
the cities vagrant animals shelters where it appears to them open
veterinary help and simply kind relation.
 And, of course, we shouldn't forget that we are PEOPLE!  We have to answer 
for the acts and their consequences.  If we sheltered an animal, she in 
which case shouldn't be on street!  I again and again remember words 
from Antoine's fairy tale Saint - Ekzyuperi "Little Prince":  "We in the answer for 
those whom tamed".
