I don’t like how my coworker treats dogs

I know this is a frustrating career, I know dogs can be frustrating. But my coworker is a hot head both as a person and as a groomer. She will talk about the grown men she beat up, talk about which barista or doctor or whatever else she made cry that morning, talk about what people she had to put in their place, and 8/10 days is in a bad mood.

If that’s just how she was as a person I could tolerate it. But she is a hot head with dogs too. She is constantly not raising her voice but SCREAMING at them, constantly cussing them out and using vulgar language, one time recently a dog who is usually good was so terrified of her he pooped several times back to back and all she could do was scream at him to not effing act that way. When she gets frustrated she brushes them in a way that would obviously hurt any animal. She yanks their legs. No words of comfort, her tactic is aggression and scaring dogs into doing what she wants.

It’s embarrassing knowing people in the front lobby can probably hear her yelling and cussing at her dogs. I know if I give her advice she won’t take it or at least not positively because she has „seniority”. And she scares my dogs too which makes it harder to groom my own. She also books herself wayyy too much which makes her frustrated and expects me to take some on even though I’m already booked. I’m planning on maybe leaving the industry but I don’t love the thought of leaving my requests that I worked with and got them used to grooming with her. I think she will undo all the progress I made.

Maybe screaming, yanking, cussing, and basically slapping with the brush and yanking hair hard with the mat breaker is something that’s normal? I believe in sternness where it’s needed but I don’t agree with how she does it.
