I am so glad you walked out. As I was reading your story, I was getting mad myself and thinking this place doesn't deserve to have any customers. How awful. They were probably just thinking they could make money on vaccinating your four dogs and not caring about anything else you had to say.
I hope you find another vet you can trust with your babies. I am exactly the same way - I have a list of questions with me and watch everything that goes on at our vets. I don't trust anyone with Kiki.
