Ah, God, that’s awful. I’m glad she has you now, and doesn’t seem to have any scars from the abuse.
Another thing about biting that I’ve found helpful: put something in the puppy’s mouth when you’re cuddling with her, like an edible chew toy. Keeps their mouths busy.
If you never give them a chance to make mistakes, you don’t have to correct them for bad behavior. It’s the same with potty training. Polaris only made a couple of mistakes, and that’s because I kept taking her out so often that she never felt she needed to pee on the rug. When we first got her, I took her out almost hourly. It was a pain in the butt, especially in the cold weather, but it paid off in not having to correct her, instead getting to praise her when she eliminated in the correct area.
That’s why I like the Clicker Method-- it’s a positive training method. My older dog was trained with the standard jerk-and-pop method (meaning that you tug on their collar when they don’t obey.) Yeah, she learned, but the younger one seems to be reacting better to training with the clicker. The only “punishment” is not getting the treat if they don’t obey, and if you’ve got yummy treats, the dog really tries hard.
If you’re not familiar with it, you basically trick the dog into obeying, and then give them a click and a treat. They learn very fast that the click sound means a reward, and they start trying to figure out ways to make it happen. The Clicker Method makes 'em think-- to try to figure out what you want to get the reward. It seems like the puppy thinks the training is more fun, like a game, than the method I used with my older dog.
Now, I’ve found that Polaris needs to be told when she’s not obeying the commands. I just say “No, puppy” and shake my head, and she tries something else. The usual method is just to wait, but I’ve found she learns quicker by giving her verbal feedback.
Dogs want to please you. I’m in Puppy Kindergarten with Polaris, and it amazes me that some of the other owners almost automatically attribute non-obedience to defiance or stubborness. They think their dogs are intentionally trying to make them mad. However, you can see the eagerness to please in the dog-- they just don’t understand what their people want.
