Have you ever seen a dog predict things

Or just genuinely be very intuitive of their people’s health? Okay so my little sister spent the entire night and some of the morning in the ER severely sick. She was acting completely normal until 10 pm. But all day he had been walking around anxiety ridden, following her and then when she started getting delirious out of nowhere he started circling her and licking her and she said she felt bad and laid down in her room and felt like she wasn’t gonna be able to get up but he went in there and started licking her face and her arms and her feet and barked at her so she got up. My mom said he didn’t calm down until we left for the ER. She’s at home now, asleep but she’s having someone watch her while she sleeps. She’s got something neurological going on and my mom doesn’t want to leave her alone. He’s sleeping at her bedside right now.
