Why is my dog shaking and lethargic after pancreatitis treatment?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 9 years and 1 month old

My dog just came home from the vet after being treated with pancreatitis. We were given Cerenia, clavamox and tramadol as medications for his home stay. He has a vet checkup again on Monday. However, he is currently shaking as he inhales and has been rather lethargic all day. Is this normal ? I should also mention he was on IV medication during his stay at the vet.

Pmcreatitis is very painful, so the shaking could be interpreted as an expression of pain. Unfortunately Tramadol does not work very well for pain, not as good as in people. The Cerenia works a lot better for visceral pain. Being lethargic is also normal with pancreatitis. Under normal circumstances we hospitalize dogs with pancreatitis, however this is not always possible depending on the area where you live and whether such facilities are available. If Bombon deteriorates or gets much worse you will need to take her to a vet before Monday, or a Pet ER.
