Hi all I am new to this site...

I have a mix American bull dog, I will be at the dog park for awhile and it seems like my dog gets board because he will jump up on me constantly.. only does this after a long period of time being at the park... he doesnt do it at home.... I will kneel down and he will just sit there right in front of my face..lol

Whats the deal, why does he do this..

Much thanks
