I noticed that homeless and stray dogs in some ways are like people. Snyshas explain why. Look at the photo. The dogs photographed on the way to the store. You can not tell by dogs that they are hungry or not well-groomed. Perhaps they are fed by people, but nearby there was no dish of water and food. No sign of the presence of people. Where people feed animals immediately can be seen. Why is it always a bowl of food put right on the road where people go, why not put it aside ?! And there is always water for animals to drink, now it's very hot ...
I think that dogs like people, are neat and adjusted to life. As the saying goes, everything is fine, they are watching for themselves and always know where to find food. And there is a category of dogs like homeless people. They always look dirty, with sores and with non-healing wounds. Not neat and tidy, ready to attack a person. Such animals as a person without a permanent residence have lost interest in life and therefore do nothing to correct the caliculation. So they live like homeless dogs.
