Just a what would you do really?
Had personal recommendations and researched a company who do supervised dog play/exercise. Excellent reviews all seemed good.
ChestyDog attended for trial session, good reports from them but noticed day after more submissive, ears back, tail tucked, quiet.
Put it down to new situation/ change to routine.
Yesterday returned after 2hours and noticed after dropped off poor ChestyDog has wounds to all 4 elbows 
They deny all knowledge, said she snapped at a dog after 5 mins so put back in van in a cage so couldn’t have happened with them.
She did not have any injuries when she left us.
Obviously she is never leaving my side again and we’re caring for wounds and will seek vet care if needed.
Would you do anything else?
Friends are outraged but if dog company say nothing happened and I’d like to think they wouldn’t knowingly let injuries happen what else is there to do?
It appears I am submissive when it comes to these things just like ChestyDog
