Sorry you had a bad grooming experience, I have, too. One thing I did afterwards was write reviews on every online review site I could. I have found a new groomer who does her nails & sanitary sometimes & I really like her-but I've still been grooming Princess myself. I did love it though, that she'd seen my review online, if she did I'm sure more did, too.
What I noticed as well is she used to never mind going to the vet, but after a tooth extraction she's scared to death to enter that building. This is how she acted with the previous groomer. I should've picked up on it but just figured she was scared of the clippers or dryer. She lets me clip her just fine.
New rule: I listen to what Princess tries to tell me.
