Why does my dog do that?
Why does my dog stand up on its back legs?

Short answer
Standing on the hind legs usually means a dog wants a better view, wants to reach something interesting, or has learned that standing up reliably gets a person's attention. It is a normal, learned behavior in most dogs, though it is worth managing in puppies whose growth plates and joints are still developing.
Curiosity and reach
Standing tall, sometimes propped against a fence, a person's legs, or a kitchen counter, gives a dog a wider field of view or extra height to sniff, look, or reach toward something interesting, whether that is a treat on a counter or an approaching dog on the other side of a gate. Small and medium breeds do this especially often simply because so much of their world sits above head height.
An attention seeking habit
Many dogs learn quickly that standing and pawing at a person's legs, or bouncing up during greetings, tends to get an immediate reaction, even if that reaction is a person pushing them back down, which some dogs still read as attention worth repeating.
A note on repeated jumping in puppies
In puppies under about 12 to 18 months, especially larger breeds whose growth plates have not closed, frequent jumping up and standing on hind legs adds repeated stress to joints still forming, so redirecting the habit toward four paws on the floor is a reasonable precaution rather than a strict rule.
Key takeaways
- Standing on hind legs often helps a dog see or reach something of interest.
- It is also a learned habit in dogs who discover it earns attention.
- Small and medium breeds do this especially often given how much sits above their eye line.
- Limiting the habit in growing puppies protects developing joints without being medically necessary.
