Hello!
Have your tried just going to the groomers to get some treats. Maybe have the groomer give them. Like, just drop in for a treat without the grooming part.

Also you might need something that acts more quickly than prozac when you are going for grooming. You would need to talk to your vet, utntheee are meds that kick in more quickly than prozac to maybe help,them relax faster.

Good luck! Keep us posted. I think dealing with grooming and vet visits for an anxious pup is not such rare issue and others here have probably some experience to add!
