High Energy Puppy Been Drowsy All Day

My 12 week puppy who usually drives me crazy bouncing off the walls has been sleepy and lazy all day. I’m usually chasing this girl around the house to keep her out of trouble, but today’s one of the laziest days I’ve ever seen from her.

This concerns me as I’m afraid she may be in danger and showing symptom of lethargy. I found a squashed Advil capsule on the stairs and she got into a garbage with dental floss yesterday. I haven’t taken action since I can’t even be sure she actually ate the Advil or dental floss. I can only wonder... (apparently lethargy is a symptom of the health complications that arise from dog eating Advil or dental floss) but she hasn’t had any of the other symptoms - vomiting, diarrheal, bloody stools...

I guess Im wondering if anyone’s high energy dog ever had days where they are totally KOed (knocked out) and lazy.

Also has your dog ever eaten ibuprofen (Advil/aleve) or dental floss and been okay?
