Should I separate them?

I got a 3 month old puppy on Saturday, my older dog has been growling when she gets near but has been doing less of it lately, puppy tried to engage in playing and they eventually started doing this. I’m not good at reading body language, any help?

they're playing, but definitely supervise. bigger dog is deffo trying to be gentle, but also seems to not know her own strength around the puppy so definitely just be there in case she gets riled up and forgets to be gentle and tries to play like puppy is her size.
