question.?

I just found out I'm pregnant and I am moving soon, so my husband and I will have to be in the car for about 7 hours.. our big, 60 pound puppy always sits in my lap when we go anywhere. If I make him sit in the back seat, he will whine until he gets his way and can come up front. Especially in the dark bc he is scared of the dark. How can I make this ride smooth? will he hurt the baby if I just let him sit in my lap?? What should I do? he is a big baby
