Protective over baby bumb

Any of you other mommies to be feeling super protective of your bumb? My sweet doggy loves to jump in bed with us in the morning and she gets overly excited. This morning she jumped right on my belly and I screamed and pushed her off of me, it was so quick, but I felt so bad after. I even hate going to my boyfriends moms house because her 6 month old pup is so energetic and will run at me full speed right onto my belly. I know my little one is well protected in there, it just makes me sooooooo nervous.
