Please just remember that because slippery elm is so good at coating and soothing the digestive tract it may also inhibit the absorption of important nutrients and medicines. I have read that it is best to only use it short-term and to try and give it separate from meals and any medicines you are giving.
I agree that you should find a new vet if you are not happy with your current one and it is ridiculous to say that sickness is induced by vets in order to make money. However, I do agree that there are definitely some that are better than others.
Good luck to you. I hope your pups get better soon.
