Pancreatitis in Canine

Question
I have a 4 yr old female boxer that weight 57 lbs.  Yesterday, she was diagnosed with pancreatitis.  The vet said her pancreatic enzymes were 2500 - what is the normal range?  He also said it could be contributed to a diet high in fat.  She eats only Purina One (twice a day - no free feeding) and gets no table food and limited treats.  What other things might have contributed?  She didnt have any glucose in her urine and seems to be in NO pain - she runs and plays and acts fine other than the GI symptoms that prompted us taking her to the vet.

Answer
The normals for a dog for serum amylase are 270-1,462 units. For Lipase it is    200 - 700 U/L.
Her range is really high. However, pancreatitis is hallmarked by pain and usually vomiting bile.

While Purina One is a terrible food and high in fat, there are other causes that can raise these levels and not just pancreatitis. I am not going to go into them right now since pancreatitis is a very common disease.
Here is an example of what it is:
"Pancreatitis is an inflammation of the pancreatic gland which is situated very close to the origin of the small intestine (duodenum) near the pyloric area of the stomach.  This elongated, thin organ has numerous responsibilities including secreting hormones into the bloodstream  such as insulin and glucagon which act in concert to regulate blood sugar levels within rather narrow limits.  As well, life would not be possible for dogs or cats without digestive enzyme production and secretion into the lumen of the intestine.  These digestive enzymes can actually cause the demise of the dog or cat if they leak into pancreatic tissues or surrounding abdominal structures.  Therefore any inflammation of the pancreas has potentially life-threatening consequences.  Pancreatitis can result from trauma, sudden ingestion of fat, toxins, viruses and other unknown causes.  One usual consequence of pancreatitis is diarrhea and vomiting.  Pain is a hallmark of pancreatitis and it is always considered a priority for treatment by attending veterinarians."

You mention limited treats but not what kind. Treats, such as milk bones, snausages, etc, are like eating Snickers bars. Loaded with fat, empty calories and tons of sugar. So giving these, even a few a day, can really pack on the fat. Her weight seems reasonable for her age and gender, so she isn't obese, but I cannot see her either.

What was the vet's recommendation for diet? If she were my dog I would get her on Science Diet light Adult formula and switch her over in a seven day period. This food is a complete and balanced diet high in nutrients but low in fat. It is very nutrient dense which means that she will require less to meet her energy needs and you will have less stool to clean up also.
Low in fat for her pancreas  and yet all she needs to be fit, healthy and active. Hills has over 50 yrs of Veterinary research behind their foods and I have fed and recommended it for over 28 yrs so I know it works.

I don't know what else to tell you at this point. If you have any other questions about diet or whatever, please let me know.
I would love to hear how she is doing in a few weeks.
