Poor dog. Sad anyone would do that. Nice to have that camera, now she knows no point in reporting “found dog”,
But I doubt there is Lab in there. Likely a cover for what type it really includes.
Judging by the pictures, I'd say the dog is a Border Collie mix. Young BCs can be a handful. Sadly, many people get one without knowing what they are getting into. The result can be what you see in the video.
