I guess we will have to agree to disagree on things.
I have noticed, however, that whenever there is a thread on dogs being housed primarily outside or a thread about bad breeding or backyard breeding, you seem to jump in to defend those practices.
I don't know whether this is because you are taking these threads personal because your dogs do stay outside in their kennels a lot, or because you have a lot of dogs, or because you do breed but don't do Schutzhund or herding, but it does seem strange to me that you are so defensive on the subject.
I see a lot of defensiveness from you on this thread as well, along with anecdotal evidence of where outside dogs were loved and cared for even though they were not allowed in the house.
"That's like saying that if the dog isn't allowed to share your bed, you really do not care about it," is your argument. That's a far cry from the reality for most outdoor dogs. Where I live, most outdoor dogs are chained to wooden dog houses, the area they can move in having so much wear there's no grass left. They're outside no matter what the weather is. Their coats are matted and disgusting looking. Maybe once every couple weeks I see someone actually outside in the yard with the dog, doing yard work or plopping down a bowl of water, not taking the dog to 4-H or grooming or taking them for a walk. These dogs are not "thriving" as you suggest many outdoor dogs do. As a matter of fact, most outdoor dogs are not "thriving" because these are the conditions most outdoor dogs live in.
You are actually arguing that it is better for a dog that has been chained for x amount of its life to remain chained, rather than be unchained and be shown what it's like to be with people, to have a warm house to go into, and leashed walks to take with a person. It's an adjustment for the dog, and a big one, but dogs can and do adjust, and many rescued dogs, whether they've come from abusive homes or chained homes or homes where they've been neglected turn out to be some of the best dogs in a good home.
My Malinois was abused and kept in a garage, pumping out puppies. Do you seriously think it would be kinder for her to have remained in that place because that is "what she's known all her life"? If so, all I can say is, you've got to be kidding me!
There are extremists everywhere who want no animal to be owned, chained or otherwise, or who want no pain used at all, whether it comes from a stick to beat the dog with or a choke collar or even a head halter. Just because some extremists are against everything does not make it any more or less wrong to keep a dog on a chain its entire life, with little to no human interaction.
That's like saying, "100 years ago, kids were forced to work in the mines and factories by age 12, and girls were forced to marry older men by age 15 - but they turned out okay and there was nothing wrong with the way they lived. Hey, there are some people now who are saying it's cruel to expect a child to do certain chores for a specific number of hours a week. So, where do you draw the line? Either you're against everything and just let them be kids, or you have to concede that most kids 100 years ago were well loved and turned out just fine."
Sorry, it does not work that way.
