Puppy vomiting & breathing hard after vet shots. Is it a reaction?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern! Any time I have administered a vaccination and the animal then begins vomiting or exhibiting any other abnormal symptoms, I treat as a potential adverse vaccination reaction. I would recommend taking him back to the veterinarian that performed the vaccination to have him examined and treated for a potential vaccination reaction. This may have nothing to do with the vaccination but it would be best to have him examined and go from there. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Thank you for using Petco Pet Education Center, formerly Petcoach. I’m sorry Theo isn’t feeling well. This is not a normal vaccine reaction and Theo really needs to go to the vet ASAP. If it is not the vet who vaccinated him make sure to let them know he had a reaction so they can note in his chart and report it to the vaccine company. I hope Theo feels better soon.

Hello there, and thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear that Snapple isn't feeling well. It isn't entirely uncommon for dogs to feel sore and puny after a round of vaccines - just like people can. They can cause soreness at the area of injection and mild general malaise, which would explain Snapple's unwillingness to move and whimpering when you try to touch her. This will probably abate over the next day, but if you notice any other symptoms such as swelling, difficulty breathing, vomiting, or diarrhea, please call your vet as these may indicate a more serious reaction. This is very unlikely as most severe vaccine reactions occur within an hour of the shots, but it is always better to be safe than sorry. If she's still acting puny tomorrow, feel free to call your vet and let them know. They may be able to recommend or prescribe an anti-inflammatory/pain reliever that will make her feel much better. Do not give her anything over the counter as it may not be safe for her. Good luck, and I hope that Snapple gets back on her feet soon!

Poor girl! If your vet gave her something for the vaccine reaction, it was likely Benadryl or a steroid or both. I would try to contact your vet to let them know she still isn't acting right and ask if you should give her anything tonight like another dose of Benadryl. If she is just tired, then this is to be expected. If she is labored breathing or vomiting or if you are really concerned, I would have her seen again by your vet immediately or take her to your local emergency clinic. I hope this helps and she perks up soon!

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.

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. Thanks for using Petco Pet Education Center, formerly Petcoach.

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.
