There is plenty of information on the web about pancreatitis.
I don't know where the author of that article got the information so I don't know how accurate some of the claims are. The one claim that there are more cases is dogs on processed food concerns me a bit and I am not so sure it is a fact. I also was a bit bothered by the claim that moderate cases do not require IV therapy. I have seen dogs die from pancreatitis that was not even considered severe. One of them belonged to my son. A dog's condition can turn on a dime when they have pancreatitis...it is nothing to play with! I do agree that any dog on IV fluids should be monitored 24/7. I take mine straight to the IMS if pancreatitis is the diagnosis.
The article you are posting is written by someone selling supplements so I do find it to be a bit concerning.
