Could my dog's pancreatitis be from neutering or anesthesia?

It is unlikely that the pancreatitis is caused by antibiotics, but we can give you more specific informations if you tell us the name of the antibiotic. Reglan is a an anti-emetic drug which will prevent any further vomiting episode and possibly promote gastrointestinal (first tract) motility. This is a common medication to give. It would be best to keep him on low fat diet (Chappie would be a good commercial diet for this purpose) for a but longer (at least two weeks after all the signs are resolved). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. Please find the time to give us a feedback about the consultation as that will be used to improve our service.

The elevated wbc count is common with both inflammation and infection of damaged tissues and although should be monitored is not abnormal given recent pancreatitis. An ultra low fat but not calorie restricted diet is generally considered best for recovery, liquid recuperation supplements are also very helpful as the gut recovers

Pancreatitis can present in many ways, the majority of which are nauseous and painful but not particularly weak and debilitated and respond favourably to symptomatic treatment and an ultra low fat diet. Severe pancreatitis is very rare and typically prevents with severe dehydration and collapse and can become life threatening, requiring hospital treatment

With pancreatitis, it is typically caused by them eating something that they were not supposed too. Usually from human food. I agree that changing Shadow's diet to a bland diet and keeping him on antibiotics (not long term) will be beneficial for him. Pancreatitis can be serious and is usually painful. Most dogs do very well on exactly what your vet is doing while more severe cases require intensive treatment and hospitalization. Here is some information on Pacreatitis. https://vcahospitals.com/know-your-pet/pancreatitis-in-dogs I hope Shadow feels better soon and thank you for using PetCoach.

Yes the medications (anesthetics and antibiotics if used) can cause digestive upsets fater surgery. Bland, small low fat meals fed little and often and a probioitc such as fortiflora can help. If he is weak and unwell you should have him checled by your vet to rule out a fever or infection of the wound

You will need to take your dog back to the vet for a recheck. The veterinarian should prescribe pain medicine for your dog. If he has not had an ultrasound exam yet, this may be the time to have one, in order to check out whether he has an abscess or tumor on his pancreas. By now he should not be in pain anymore, especially since his body functions have returned to normal (no vomiting, no diarrhea, and eating and drinking.).

Oh no. That was not very wise of him to eat all that peanut butter. Unfortunately whats done is done. The best thing you can do now is to feed him a very low fat diet for the next 7 days. I would recommend the Hill's Science diet I/D low fat. Boiled plain chicken and rice can be given tonight if you can't make it to your vet right away, but after that go with the prescription food only, then slowly transition him back to his normal diet. You will need a prescription from your vet to purchase the food at your local pet store. Best of luck with your Beagle and I sure hope he doesn't have another episode of pancreatitis. Best wishes and take care.
