My dog vomited after Lepto vaccine today. Should I be concerned?

Getting vaccines can be stressful and painful to the dog, and Scrappy may be feeling a little off from all the stress of the day. I would continue to monitor him, and I would be worried if he starts having protected vomiting or diarrhea, develops a swollen face and muzzle, and starts having trouble breathing. Those can be signs of a rare but serious vaccine reaction, and in that case, I'd take him into a vet right away. Try putting a cold compress on where he received his lepto vaccine to see if that helps him. You can apply for 5-10 minutes a couple of times a day. Typically a dog is back to normal within 24-48 hours after a vaccine. Best of luck, I hope this helps.

Well that depends on the severity of the adverse reaction. If she is having a mild vaccine reaction (1 bout of vomiting, loose stool), then an anti-histamine (i.e. Benadryl) can be given in most cases and will calm the reaction down. However if she is having a more severe adverse reaction (i.e. continuous vomiting, anaphylaxis, severe lethargy, anorexia), then she will need an antihistamine shot (for immediate reversal), +/- steroid shot from your vet , +/- fluid therapy and close monitoring to ensure that the reaction subsides and that she remains stable.

The safest thing would be to contact your veterinarian who is familiar with the case so that they can recommend further. Have a great day!

While not considered a "core" vaccine, the leptospirosis vaccine is highly recommended for dogs who may be at risk for contracting leptospirosis, as it is a disease that can lead to agonizing deaths in both animals and humans.

My suspicion is that this is injection-site pain and not a "true" vaccine reaction, however I do know that dogs (especially small ones) can be pretty painful in the limb they were vaccinated in for up to 36 hours afterwards. I wouldn't call it "normal" but we definitely see it - both of my own small dogs were painful after their last lepto vaccine. Because they can be pretty miserable, I would recommend calling your vet and asking if they might dispense a bit of pain relief - perhaps only 2 - 3 days worth - to make sure Ted is comfortable over the weekend. And if you see other more concerning signs - swelling about the head or face, difficulty breathing, vomiting, collapse - take him right into an emergency facility.

Hello. It is not unusual for a puppy to feel a little unwell after receiving vaccinations, but these reactions rarely require treatment. Most symptoms will pass in 12-24 hours. If Baxter is otherwise feeling OK, or sleeping quietly, then leave him be. But if the vomiting is intractable, or he develops any diarrhea, quits eating & becomes significantly lethargic please see your veterinarian as soon as possible.

Hello, sorry to hear about Ella. It sounds like she may need continued medical support to get over the allergic reaction she had to her vaccines. This may be in the form of fluids, benadryl or potentially more steroids. She should also have her pancreas enzymes checked to ensure she is not having pancreatitis. The lepto vaccine has definitely been associated with adverse reactions. It would be best to have Ella evaluated by a veterinarian if she is not doing well. Hope this helps and best of luck.
