I’m just wondering if anyone knows anything about this? My dog keeps chewing peoples fingernails if she’s licking their hand or sees their hand near her. It’s not aggressive at all, just very strange. She’ll be licking someone’s hand and then start biting their finger nails, we don’t know why she’s doing it. She also bites her own nails despite us keeping them short and looking after them, she’ll sit there and violently chew her nail for 5 minutes and then just stop. We don’t really know why she’s doing it, she’s a rescue so maybe it’s a self soothing thing? Any thought? Thanks.
