**Why do EPI dogs have a bad smell after starting powdered pancreatic enzymes?**
The bad smell comes from putrefaction, which is the process of decay in organic matter.
Until now, many of the foods your dog ate were not digested well, leading to a buildup of undigested food that fermented. Now that your dog is using enzymes, these nutrients break down better, releasing those trapped particles and causing the smell. It wont last.
Researchers have also found that EPI dogs have higher levels of putrescine and spermidine in their blood, which are known for their foul odor. Changes in these molecules may explain the smell some EPI dogs have when they start enzyme supplements. *
