Jackson possibly got pancreatitis after a family BBQ too. I think it was the sausage that did it.
I say possibly because I'm still not 100% sure if it was or if it was just upset GI system.
I had to take him to a different vet because it was of course on a Sunday and a REALLY long story short... they were total rip-offs and scared me very badly and I ended up doing a bunch of unnecessary visits/tests. When they finally told me that a cPL test existed to test for pancreatitis, we did that, and it came back negative. So even though his lipase levels were high in the bloodwork, I didn't have any prior bloodwork to base it on so it could've just been his normal bloodwork. Anyway once I talked to my regular vet and showed her everything, she assumed it just a bad GI upset.
Jackson ended up staying overnight on IV's all night at the 'other' vet and I regret that because I think he would've been perfectly fine at home with some sub-q fluids (which they had me come in for 3x during that week, and charged for each visit, etc). It ended up being a $1500 ordeal.
We did the really low fat diet for a few months afterward just to be safe anyway but I was never happy with his body condition or hair, so we just went back to a regular diet. I still avoid super high fat things in general (I won't buy dog treats extremely high in fat) and he's not allowed any fatty table scraps (ham, bacon, sausage, etc) but other than that, everything has been normal thus far. I think this was 3yrs ago now.
I do know that pancreatitis CAN be very dangerous for certain dogs, and it depends on if it's a chronic issue or not.
It seems Blaze had a REASON for the attack, too, and you know what it is, so it's probably a one-time thing, but I too would just stick on the safe side and keep food and treats low fat. Ex: treats, I use Cloud Star Buddy Biscuits. Most of them are no higher than 5-8% fat or so. Any treats over like 12% fat, I won't do. Dog food, I won't go over about 18%, but I'd prefer to stay in the 14-16% range. For dogs with chronic issues, you usually don't want to go over like 10-12%.
