Drooling Baby

Lady May turned One at the end of March, she’s always drooled a lot when she’s excited but the last couple days I’ve noticed she’s been drooling a lot more in general, almost excessively. Walking up from a nap her bed will be soaked and she’ll have long strands hanging out of her mouth, this is new. She’s her normal, energetic self, eating and drinking normally. Looking for advice or thoughts from other basset hound parents! Is this normal or cause for concern?
