You need to actually document the incident, exact time it occured, what happened, etc. Even better, when you see it occur, go and get the manager of the store that very minute. You can't say weeks later "well I saw her do this..and that..." Do something about it when you SEE it happen.

I know, because I work at a grooming salon and there's one groomer that is sometimes not very nice to dogs (or customers for that matter). I don't think she's in the right line of work, she has no patience for animals. The manager said the only way we can do anything is if we report an incident when it occurs, and she's written up for it.......not " well one time I saw her do this..." if that makes any sense.

micki76, cut OFF a dogs ear??? Was the groomer fired? How did the owners react? Poor dog!

p.s. I hope nobody thinks all groomers are bad because of a few....they're not...
