When I go to the Dog Park it seems that all the very big dogs like to sit on my feet, what's up with that?

these dogs have a connection to they want to show you that they have affections for you be kind in return and show that dog that you like him or her and you appreciate their kindness.old dogs thrive on being soical so make sure next time you inform this dog that you appreciate its kindness

I notice that too. I have three. Two big one little. I had a Great Dane just come up, unleashed, and just cuddle up to me. Owner apologized and stuff, but I assured her there was no need to. I liked the dog and my dogs like IT. LOL They do do that. I don't know. And when I let my dogs of the leash at a lake or something the biggest dog will come up and say HI and snuggle up at my feet or try to jump on me thinking they are a lap dog. I don't know. I really do think Dogs know who is good and who is bad.

maybe they just like you

they are liking you
