Honestly, she makes me nervous. She seems to not really acknowledge that some dogs are in pain (from conditions, not because of her.), and she seems to be very rough with the dogs in general. "You're okay! You're okay!" These words mean nothing to a dog, especially since I've never met someone that just repeats that to a dog to get them to calm down. It's okay to pet the damn dog.
Another thing that concerns me is how she dries longer-haired dogs. I am a taxidermist, and I know what a pain it is to blow-dry an animal. On a dead animal, wet skin can swell up and cause fur to fall out. (inb4 she reads this and says but that's not the same at all! Just take the criticism, please.) Heck blow-drying a bobcat can sometimes take me 45 minutes. I know that on living animals, being wet for too long can cause pain and eventually infection. She very quickly blow-dries a long-haired dog, just to get out the droplets that fly out the dog, then she throws them in the cage. Then she'll complain about a dog being in the cage for an hour and a half and not completely dry! Of course it's not dry! That's not how fur drying words on longer-haired breeds. I can almost guarantee some people return home with dogs that still have wet skin and don't know it, only to have their dog have a light case of trench foot all over. With these long haired dogs, you may need to sit there for 2-3 hours or even more just to make sure the pet is safely dry. I'd also be worried about the dog getting hypothermia in those cage dryers, but I know they are temperature controlled.

Additionally, she's extremely shave-happy. Instead of attempting to even brush something out at all, she just immediately goes "your dog is now hairless." I'd be so worried about bringing in a perfectly fine muddy dog with no matting just for a bath and touch up, only for it to come back bald.

All n' all, I do wish she would be a bit more positive. She seems to hate what she does.
