Any knowledgable owner would not allow such behavior from a big dog. It is not safe, and very dumb to allow a dog that is going to be over 100lbs jump on laps. 
Thats like letting a big dog (as a puppy) jump on people when they are excited… sure its kinda cute when they are puppies, but when they are 100+ lbs… and jumping at people, all of a sudden it is not cute, nor funny but dangerous.
I know what your sayin baby… but it ain’t cool to have big lap dogs.
I’m going to try and get some pics of our dog today… it’s Marias, but I’m the only one who gives it any attention.
