Sadly,
in this neck o' the woods,
If you see a dog on a chain, odds are, that is is whole life.
And he probably never gets let off of it either.
If you see a pit, rottie or dobie on a chain, odds are even greater he's getting even worse treatment. But that is just my cultural observations from conversations.
In this neck of the woods, you never see dogs on a chain, although there is supposed to be a fine if your dog is found wandering around off it.
It appears you are assuming that these dogs never get off it, do you camp outside these homes to see?
How does a Rottie, or Dobie on a chain automaticaly mean they are being abused in your mind?
What does this have to do with ones culture?
