When it comes to jumping on your lap, the size of your dog doesn't always matter when he really wants to sit on your lap. It's comfortable for you to enjoy a small lap dog as you sit together on the sofa, but large dogs often long for the same type attention for similar reasons. Knowing the reason behind the behavior helps you understand whether you need to take action to change the behavior or if it's OK to allow it. The following are reasons your dog like sitting on your lap.
As a sign of Hug's: The same way your dog is part of your family, he sees you as part of his pack. Getting higher than your feet allows him to relate more closely to you — he gets more petting and caring than when he's on the floor alone. When your dog jumps on your lap and you caress him, you support the behavior and letting him know that if he needs some petting; all he needs to do is settle down on your lap. Hugging your dog gives both you and your dog happiness.
When he feels insecure: You add stability and security to your dog's life, so it's normal your dog would run to you when he's not so certain of a situation. Getting up on your lap allows him to feel calmed and protected from strange dogs, people or places. Encouraging your dog, in this case, might not be a good idea. It can strengthen his behavior, making him unable to deal with new situations without your comforting hand. Allowing him to deal with new situations on his own, not on your lap, can help make a more confident dog.
To show Supremacy: In a dog state of mind, there's always an alpha dog, who have the first right to anything, food, water, toys and beds. When your dog bounds on your lap and seeks attention by barking or pushing his head under your hand, he might be trying to declare dominance over you. If you have more than one dog, he might be trying to show dominance over them. Let him know you're the boss by turning your back on him when he wants affection and giving him attention on your schedule instead of his.
To Comfort you: When your dog sits on your lap when you are sick or as you cry, he's likely offering you comfort. He can't tell you how sorry he is that you are sad or don't feel well, but many dogs can sense emotions and illness. Getting close to you makes him feel better, so he thinks letting you get close to him makes you feel better — and he's probably right.
As a warning to other dogs: When he sits on your lap in front of other people or dogs, he might be marking you as his own so no one else can steal you. In his mind, he's warning others away from you by sharing his scent, which helps keep you safe.
