Is it normal for a puppy to be tired and not eat after vaccines?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Milo. I agree, this does sound a bit excessive to me. I think if she is still acting this way in another 24 hours, I would take her back into the vet to get checked out again. I hope this helps!

Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Lethargy, fever and inappetence can occur 24-48 hours post-vaccination. This is not uncommon. If it has been longer than this, it is likely unrelated to the vaccines that a good reason to have Saski evaluated by your veterinarian to ensure that there is not something else going on. Good luck! Have a good evening!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Kane just recently had his first series of vaccinations, this could be an explanation as to why he is not moving around as much. If he is still eating and fine otherwise, I would keep an eye on him for another 24 hours. If he does not perk up or he worsens, then I would recommend having a veterinarian examine him so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Puppy's getting sleepy after their shots is a normal reaction to vaccinations. They can also have a low grade fever and/or one bout of vomiting/diarrhea normally that are no cause for concern. The concern arises when your pet is severely lethargic, not eating, non-responsive, pale gums, or excessive vomiting/diarrhea. If you notice any of these symptoms then it is best to take puppy to a vet asap for immediate care, because a mores serious vaccine reaction is occurring at that point.

Hi Shawn! You can see some lethargy up to 48 hours after a cat gets it's vaccines, and this is normal. It is concerning that Bugsy Malone (love his name!) is eating less, but hopefully he is eating something. Try to tempt him to eat with some boiled white meat chicken (no bones), or by soaking his dry food in tuna juice. The bumps will be localized reactions to the vaccines, and should disappear in a few weeks. If he is still lethargic and eating less tomorrow, then I would take him back into the vet for an exam. I hope this helps!

Some poor appetite can be considered normal after vaccinations. Vaccines stimulate the immune system to help protect your pet from common diseases they could be exposed to. Vaccines can sometimes cause minor changes in appetite or behavior. Usually I tell clients some decrease in appetite and decreased activity can be normal for 24 hours but for any issues lasting more than 24 hours they should call me ASAP. Some of the major issues (although rare) associated with vaccine reactions are trouble breathing and anaphylactic shock. If you notice any trouble breathing, severe lethargy or swelling of the face or at the vaccine site you should contact your veterinarian as soon as possible. If the poor appetite is still an issue after 24 hours or If any other issues are going on contact your veterinarian ASAP.

I'm sorry Milli isn't feeling well! It's relatively common for dogs to feel lethargic or sore after vaccines. It usually resolves on its own within 24 hours. If she has any vomiting, diarrhea, facial swelling or hives I would take her to the vet right away. Otherwise, make sure she has access to water but I'd call your vet tomorrow if she's not back to normal by then.
