I will. I think what they don't understand is that any one thinking of going raw for their pets has most likely done a fair amount of research already. I mean it is way more convenient to open a can or bag of dry food than to go through the whole process of making it, and the decision is usually made after we see a health crisis in one of our pets and are looking for ways to make things better! It's certainly not an easy process, not just the making but the effort of trying to switch them over to it!
I have a feeling that a lot of vets don't recommend raw for that reason--it's hard to get right, and they don't want to see pets who are raw fed by owners throwing random pieces of only muscle meat into the dish.
You might tell your vet about the existence of premixes the next time you see him. It would be interesting to get his reaction.
