Many dogs with chronic pancreatitis and those prone to recurrent attacks of acute pancreatitis do better when fed diets that are low in fat (around 8%).
Dogs that suffered a single isolated bout of pancreatitis may be able to tolerate a slightly higher fat content in time, but it makes sense to take things slowly, allow your dog time to heal, & err on the side of caution by not feeding anything over 12% fat.
Also pay attention to the fat content in your treats because many can be very high in fat (as can table scraps!)
Similarly, if you own a breed prone to pancreatitis (e.g Cavalier King Charles Spaniel, Miniature Schnauzer, Collie,Boxer, Cocker Spaniel, Dachshund, Briard, Shetland Sheepdog, Miniature Poodle, German Shepherd, Yorkshire Terrier), opting for low-moderate fat foods may be a sensible precaution, as well as ensuring they stay a healthy weight & have lots of exercise.
Pancreatitis is a scary & painful condition which can cause lasting damage, but once the fat is managed most dogs can live the rest of their lives without ever having another incident.
The foods listed below range between 8% & 12% fat.
