Our pit bull Ruby does the same thing - she’s also a rescue. Pure unrequited love.
Our neighbors had a pit bull that would stay at our house once in awhile. Sweetest thing. It would climb into our daughters bed, go under the covers then pop it’s head back up and lay on the pillow. It was cute, and it could be there when I was reading to my daughter her goodnight book or telling stories, but I made it leave when it was bedtime (much to the wailing of my child and wife).
“I know - it’s a sweet dog - but even sweet dogs can nip sometimes if it gets kicked in their sleep or something. And they have such powerful jaws - no, it’s not sleeping there.”
Heh - “Seeing as these are the most powerful jaws of ANY canine, and it’s face is right next to yours - you got to ask yourself one question. Will it bite you or not? Well - do ya feel lucky? Punk?”
So does my Bully, Tigger. She often sleeps with her head on my shoulder. Seldom leaves my side. She’s a Heintz that someone dropped in the nearby forest. Came running up to me as I cleaned out the car. Jumped in, started crying (talking) and giving me kisses. She clearly says “I LUV YOU!” We’ve been best buddies since
You should love her back.
