Vampire Bat Dog
Marked NSFW because I know some people don't like blood.
IIRC unknowingly to us (this was back somewhere 2012 - 2014ish) she'd got a tiny slice on her tongue, but then carried on obsessively chasing that ball around for 15 - 20 mins while we were doing daily chores in the stables; so we found... this.
Glad it wasn't in a public park. Can almost see and hear in the busybodies disapproval and me trying the clichéd "she's friendly" response... (For the record, she absolutely was, made a positive impression on basically every she met during her entire life)
