Many consider the Golden Retriever to be the ultimate family dog--they have a very pleasant manner, a ton of energy, and are extremely loyal. On top of all this, Goldens are highly intelligent and learn very quickly. Using a kennel can give your pup a safe place to rest both night and day. It is a dog's nature to find a den in the wild. If you handle his training properly, he will quickly come to see his kennel as his den.
Once your pup sees his kennel as a den, you will find that he likes to sleep in it at night, take naps in it during the day, and sometimes simply go there to get away from it all and relax. You can also use the kennel as part of his potty training and as a place for him to remain safe when you are out of the house.
What you are trying to achieve here is to teach your pup to obey a simple command or cue word such as "kennel" or "go crate". Take your pick, but once you choose the right word, stick with it. Rather than simply demanding that your dog goes into his kennel without giving him a good reason, you need to make him see the kennel as his den, a place where he actually wants to be as much as you want him to be there or more.
One way to do this is to make his kennel as comfortable and "den-like" for him. This will make it far more appealing to him, which of course should make it that much easier to successfully "kennel train" your Golden. The rest of it, like most forms of training, relies on you. You need to have the time and the patience to work with your pup until he masters this skill.
It all starts with going shopping for the right size kennel. If your Golden is a pup, you may need to start with a smaller kennel and work up to one that will fit him when he is full-grown. Alternatively, you can start out with the larger kennel and create a makeshift wall to shrink the kennel to fit your pup's size. A kennel that is too big could make your pup nervous. It could also be so big that he treats one area as his den and then use a corner or spot as a bathroom, something you really don't want. However, there are a few supplies you will want.
Since you will be training your dog to stay in a kennel with the door closed you need to be patient and prepared to work with him for a while until he is quite happy with his new den.
