OMG! I would be so POed at that groomer. I feel so badly for you and your little Rex. I don't know that there is much more that can be done in regards to that groomer. I'm glad that she took the responsibility to pay for the vet bill. I guess the only other thing I would do is inform all of my friends about the experience and let them decide if they still want to take their dog to that groomer.
I agree that someone on YT will come up with a creative way so that you can take him to work with you. I think that is very important especially during his recovery. Poor baby.
Hugs to both of you.....
