Oh, Karen,
I'm so sorry to hear of the distress this is causing you and Jasmine. I just looked up to see what could be happening and 'they' were talking about a person using OTC flea meds and the toxic reaction. I'm not sure what was in the flea bath, but probably some of the same stuff as OTC meds. Have you brought her back to the vet yet? Hopefully, the vet can get to the bottom of this and treat her.
I would also hold on to the vet bills and bring them back to the groomer's shop. Was your groomer the owner or an employee? When we bring our boys in, they always go over what we want, what we don't want and they 'inspect' the dogs right then, for any possible problems. I have also told them, 'Any questions, call my cell'. I've never had a problem w/ these ppl.
I hope you and Jasmine have a peaceful night and you can get some answers from the vet. I know you feel badly and I know you love your girl. She knows it, too.
I will keep you both in my prayers.
God bless. Alice.
