sorry to say but the shaking/shivering is most likely caused by being in pain. We had a dog who had severe kidney problems. A young dog at that who would shiver laying down on her side and pull her back legs forward. Hunched back slightly when she walked. Next time the dog takes a pee, get a good look at stream of urine. Note color. Real clear urine is not good neither is red tinged. Should be yellow. Also, did the dog get alot of turkey treats around christmas? My neighbors dog had issues from eating turkey and fatty skin.
What are the signs of pancreatitis?
The signs can vary from mild gastrointestinal upset to collapse and death. Most animals present with common gastrointestinal signs of upset, such as:
Vomiting
Not eating
Painful abdomen, hunched appearance (more common in dogs
Fever or below-normal body temperature
Diarrhea
Depression
Dehydration, evaluated by noting sunken eyes, dry mouth, and increased skin turgor (skin tents when pinched)
These signs are not specific for pancreatitis, and can be seen with many gastrointestinal diseases and conditions. All or some of the signs may be noted in an individual patient with pancreatitis. Cats can be especially difficult to diagnose due to the vague signs they exhibit with chronic pancreatitis - depression/lethargy and poor appetite are seen with regularity, and gastrointestinal signs of vomiting, diarrhea, and / or pain are seen intermittently.
How is pancreatitis diagnosed?
Your veterinarian will evaluate your pet's history (i.e. getting into the garbage, eating a lot of food they normally don't - especially fatty foods, etc.), do a thorough physical examination, and likely do blood tests to rule out other diseases and to check pancreatic enzymes. Radiographs may also be done to rule out a gastric or intestinal foreign body or other GI diseases or conditions.
I was always told plain pumpkin was good for dogs tummy. She had to also boil hamburger, to get out the fat, drain rinse and mix with some boiled rice to get her dog to eat
