Well yanno what? Good for you!
Good GOSH I am sick of seeing you post this over and over as if it makes you better than any of us. I own 10 dogs. I don't tether, but I do crate and I do have fenced yards for my dogs. 6 of my 10 dogs would have been DEAD if I didn't take them. They would have been euthanized. My dogs LOVE their crates and are in them often, for hours at a time, even when the doors are open.
I close the crates when I give raw bones and chewies, so each dog can enjoy their treat without having to worry about another dog taking it. I also close the crates when I cannot supervise them in the house, so they don't get into things they shouldn't that could cause harm to them. The dogs don't care, they don't try and get out. They just relax and often sleep. I know this because when I come back, they're just there. Their paws aren't bloodied, their blankets aren't all messed up, the crates aren't broken. They're very relaxed.
Anything can be abused, from crates to tethering to training collars to training methods. It is NOT black and white.
