Stopped caring about badges the second I saw one of those Denver accounts posting 47 pics in two hours like that's normal human behavior. Verified just means somebody paid or got lucky, it says nothing about whether a real person is behind it. Scroll down to the comments and you'll see the same heart emoji spam forty times from twelve "different" accounts that all joined the same week. That bot farm replying to itself is the tell every single time. Once you spot that pattern you can't unsee it. Badges are a joke now and I trust a random account with 200 followers way more than some blue check with 12k bots.

Sounds like your vet just told you what every dog owner already knows, dogs sleep a lot and it is not some big crisis. 16 hours is normal for a big dog, you were just overthinking it.
