our puppy is almost 6mo old but lately every chance he gets he stands on my feet. He's a lab so this is really uncomfortable but he won't move I actually have to push him really hard and then slowly he gets off. He does this when I sit down to eat he does under the table and sits or lays on my feet when I'm standing or doing something he comes over and stands on me.

why is he doing this and how do I correct it?

Most of the time it's a security issue. He's feeling a little insecure, due to his age, and he's trying to keep close contact. It's sort of like a toddler hanging onto your leg.

I'd probably nudge him gently with my leg and tell him "Off." Praise him when he gets off your foot. I'd increase the amount of exercise he gets. And I'd enroll him in an obedience class to give him more socialization, and also give him mental stimulation and more confidence.

In that story...
I remember my dog who pass away...
He always put his feet over my feet...
Every time I am standing near at him...
My brother said that if he gets near me...
I will put my feet into his feet...
And one time I do that...
I am surprise he gets angry with me...
I don't know why he act like that...
