После Второй мировой войны главнокомандующие вооруженными силами четырех держав-победительниц стали членами

Many people complain that dog owners do not look after their pets for a walk and do not pay attention to the fact that they are shitting in the wrong places. People offer to penalize "offenders" or even arrest them. 
I think that the arrest is not necessary, but to fine for the troubles caused by the animals need. Although I think that everything is so used to it that nothing will be done. 
People should be care of their pets , because other people don't like when they pass near the foul of dog or cat. Also, if they  foul on the lawn which is a private property or public place their owners should be pay. 
On the other hand, the owners of the pets may not have time to work, or for some important cases, so they have to walk with their animals not far from their homes or to the nearest public places. They  can be understood too. 
I think if I were the owner of the animal that wants to walk, I would not paid attention to where I walk with him. In the end we are not that, life is like that. (удалите это предложение, оно слишком русское)))
To sum up, I want to say - if you have got an animal that wants to walks, walk with it in the right places, or do not keep it.
