Since you have three, it would probably be economical and better for your girls to have the groomer come to your hosue so you can monitor. A mobile groomer is a great solution and you can pop in and out at will to make sure your babies are not being abused.
I hope they were not abused but I have heard so many horror stories about groomers that I have never left mine with a groomer.
I have heard that spaying females can cause incontinence in some dogs but I don't know if it can happen a long time after spaying or if it happens immediately.
Good luck with finding a solution.
BTW, does your groomer use a blow dryer attached to the side of a crate for drying? I had a groomer tell me to never let a groomer dry a dog any way other than by holding a blow dryer and doing it manually. Too many dogs have gotten overheated and perished in this manner. Maybe this is why your one little one is afraid of the crate now.
