Usually, pet owners are focused on keeping their dog off the bed, especially if you have a large breed dog--what is cute as a puppy may not be cute when your dog weighs 100 pounds! But what if your dog won't get up on the bed, and you want him to join you there. Well then, you will need to teach him to jump on the bed and maybe provide a little aid, depending on what the issue is that is preventing your dog from joining you on his own.
For some dogs, jumping on the bed with their owners is not something that comes naturally. It may be that your dog has a physical limitation due to size or an orthopedic condition, in which case you will need to provide your dog with an aid to help him get up on the bed. Doggy stairs that allow your dog to reach and jump onto furniture can be homemade or purchased commercially through pet supply stores. Sometimes, the dog is just afraid to jump on the bed, and training is required to overcome this anxiety. If you have recently added a mature dog to your family that was taught not to jump on furniture in their previous home, and you want your dog to join you on the bed now, you will need to help your new dog understand that he is now welcome on the bed. This will require some patience and training so as not to confuse your dog. Ideally, you will ask your dog to jump up on the bed by patting the bed and providing a verbal signal, such as 'come on up', or 'jump on the bed'. Your dog will then jump up and join you on the bed for cuddles, or to curl up and sleep.
Many pet owners enjoy having their dogs sleep on the bed with them for company, or to keep their feet warm, and most dogs love to join their owners, so motivating your dog to jump on the bed is usually not hard, but a dog that has experienced pain when jumping on furniture due to a medical condition, is anxious about jumping, or was previously taught not to jump on furniture will require some assistance learning this behavior.
