What Happened

A while back, I decided to start giving my 10-year-old golden retriever, Max, some fish oil supplements. I heard they were great for his skin and coat, so I figured why not give it a shot? I followed the recommended dosage for his size and started giving him one capsule a day.

At first, Max seemed to be thriving on the fish oil. His coat got super shiny, and he had a ton of energy. But then, after a few weeks, things took a turn. Max became sluggish, stopped eating, and started having tummy troubles like diarrhea and vomiting.

I rushed Max to the vet, who gave him the diagnosis: pancreatitis. It’s a serious inflammation of the pancreas, and it can be really dangerous if not treated right away. Turns out, the fish oil supplements were likely the culprit behind Max’s pancreatitis scare.
