@Setanta,
Quote:The problem is, she's fully grown--three years old--so you have the old dog/new tricks problem.
There is no problem--dogs are fully capable of learning at any age. If anything, a three year old should be easier to obedience train than a puppy because they are less hyper and better focused.
Not only that, she sounds like a reasonably well behaved dog. She's not running around chewing up everything in your house, she's not barking constantly, etc., so she may well have had some past training and she may be very receptive to any new things you want to teach her. At the age of three, she's hardly over-the-hill.
Quote:No, she's just pretty much oblivious.
Only because she hasn't been trained before. No dog is born knowing how to heel on a leash--it's not a natural thing for a dog to do. She has to be taught to heel and taught not to react to all those distractions when she's out for a walk. She's able to learn all of that, but someone has to teach it to her. You have to start from scratch, just as if she were a puppy.
If you suddenly found yourself in a new environment, where there were different rules for behavior, or a foreign language was being spoken, wouldn't you want someone to help you learn what to, do or help you understand what was being asked of you? She needs someone to patiently teach her, and reward her, with praise or a treat, when she gets it right.
You can wait for her to learn how to walk on a leash by trial and error, because it will be unpleasant for her when her collar pulls on her throat, but she won't really be learning that you're the one in charge of the walk, and where she's entitled to go when her leash is on, and not to lunge or bark at things that distract her.
Haven't you ever trained any of your other dogs before? Did you just wait for them to figure things out on their own?
Maybe because I've always gotten my dogs when they were puppies, between 2-3 months old, I've always considered basic obedience training part of what I had to do as the owner, if I wanted to live with a well behaved dog. And the training, and watching the dog learn, has always been enjoyable, for both the dog and me, despite occasional frustrating moments. Dogs like to learn, even those who are no longer puppies, because it's mentally stimulating for them, just as it is for us when we're learning something new.
