Not that helpful but people used to leave their dogs in that dog park while they ran errands (there is a pharmacy) or played ball. I’ve see dogs in the dog part unattended. Sorry she’s abandoned. Hope she finds her parents. They may not have social media. Then in the other hand—Hope the owner is OK. I fainted once while walking my dog and was taken to the hospital in an ambulance. Luckily, someone took my dog home. Sending prayers for a happy outcome.
