Far too many people still seem to think that crate training a Schnauzer is cruel. What they don't realize is, providing you approach this training in the right manner, there is nothing cruel about it. In fact, most Schnauzers end up falling in love with their crate. "Why?", you might ask. In the wild, dogs have always sought out a small safe place they could call home. With this in mind, there is nothing cruel about crate training your pup, in fact, it is quite the opposite.
The only time using a crate for your dog is cruel is when you force them to spend too much time in them, as this can be bad for their health. Remember that puppies have a much smaller bladder and cannot spend excessive amounts of time in their crates without going potty.
The task at hand is simple, you are trying to take advantage of your pup's natural instinct to find a den and use it to convince him to see the crate as his den. It takes far more than just a little time and effort to make this happen. However, the end results more than justify the means. The thing to keep in mind at all times is that your pup wants to have a "den" of his own, somewhere he can go to get away for a little peace and quiet, or simply to take a nap.
Your job is not only to teach him to see his crate as his den but to train him to stay in for what can be several hours at a time. Chances are good that once your pup understands what is expected of him, he will spend a lot of time hanging out in his den without the need for him to be told to go there.
Before you can start crate training your dog, you need a crate. The first crate should be just big enough for your pup to stand up in and move around a little. If you make it too big, he will find a spot in it to use as a potty. When the fit is just right, and it's all set up nice and cozy, what dog could possibly resist? To make it cozy, add a mat or carpet to the floor, a nice bed, a blanket, a source of water, and a few new toys.
You should also have a plentiful supply of your pup's favorite treats on hand to give out as rewards. Along with treats, you need plenty of patience and time to work on this new skill with your dog. Keep your eye on the prize and work with your pup until has mastered this skill.
