Why Does My Dog Jump Up on People?

Jumping up is a behavior many dogs display, often when they’re excited to see someone. Though typically done out of friendliness, jumping can become problematic—especially with larger dogs or if it causes discomfort to guests. Understanding why dogs jump up can help address the behavior more effectively.

1. Seeking Attention

Dogs often jump up because they’ve learned it’s a reliable way to get attention. When a dog jumps and the person responds—whether by petting, talking, or even pushing them away—they’re receiving the attention they crave. This reinforcement strengthens the behavior, making them more likely to repeat it.

2. Excitement and Greeting Behavior

For many dogs, jumping up is their way of saying hello. In the wild, puppies lick their mother’s face when she returns to the den, and jumping can be an extension of this instinct. Your dog might jump up to greet you or others out of excitement, trying to get to eye level to interact in a familiar, comforting way.

3. Lack of Training

Without training, dogs don’t understand that jumping up is an inappropriate way to greet people. Without clear boundaries, they naturally revert to behaviors they would use with other dogs. Proper training can help teach them a more suitable and respectful way to express their excitement.

4. Overexcitement

Some dogs, especially those with high energy levels, may jump when they’re excited or overstimulated. This could happen when you come home after being gone or when new people visit the house. Their energy can spill over into behaviors like jumping as they try to release pent-up excitement.

5. Mimicking Behavior

Dogs are excellent observers, and they often mimic the actions of others. If your dog has seen other dogs jumping up and getting attention, they may copy that behavior. This is particularly common if they’ve observed that jumping leads to petting or playtime.

6. Resistance or Confusion

Jumping up or rearing up can sometimes be your dog’s way of expressing resistance or confusion. If a dog feels unsure about what they’re being asked to do or wants to stop a situation they’re uncomfortable with, they may jump up as a way to communicate their uncertainty or reluctance. This can be a form of “pushback,” signaling their discomfort or confusion.
