Why is my dog lethargic and sad after his rabies shot and moving?

Updated on September 23rd, 2025

Pet's info: Dog | Labradoodle | Male | neutered | 120 lbs

Hey there! My dog had a rabies shot one week ago and he doesn’t seem very well. He seems very lethargic and somewhat sad. He still eats and drinks normally and likes his walks but he seems off. Do you think it is because of his shot? He is 8. Also, we are selling the house so for the past two weeks he was with my dad but is now home. Do you think he is upset about being moved? Please let me know

Sometimes vaccines can cause dogs to feel a bit groggy, a bit like a person getting their inoculations. However it doesn't tend to be that pronounced. Dogs are very sensitive to new environments and stress so so wouldn't be surprised if a lot of it is down to the changes occurring. Whilst he is eating and drinking normally I wouldn't worry too much. However if he deteriorates or dies not return to his usual self in a few days it would be best to get him examined.

Why is my dog lethargic, not eating or drinking after his shots?

Hi and thank you for using Petco Pet Education Center, formerly Petcoach. He may be having a vaccine reaction. Sometimes it can be painful at the injection site and dogs can be sore. I would recommend calling your veterinarian tonight and letting them know that Wolfie is not feeling great. They may prescribed him some anti-inflammatory medication, fluids or anti-nausea medication to help him feel a little better. Good luck!

My dog got a rabies shot too soon. Is he okay? Why is he tired?

This is absolutely no problem. We often vaccinate against rabies more often when dogs need to travel abroad and need to show a particularly high vaccination titer. It is a normal side effect that your dog is a bit tired after the vaccination.

My puppy is lethargic and not eating after vaccine. Is this normal?

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.

Why is my dog lethargic, not eating, and eye discharge post-vaccine?

Unfortunately these symptoms are vague and could be a sign of a number of different diseases. He could have some kind of infection, organ damage, or an autoimmune disease. I think the rabies vaccine was likely unrelated especially if he was showing some symptoms prior to vaccination. I’d recommend rechecking with your vet if Hurshy still isn’t improving - they may want to check blood work or perform some other tests since he hasn’t responded to treatment.

My dog is sick after vaccines: fever, tired, not eating. Is it normal?

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!

Is my dog lethargic & not eating due to rabies shot after being lost?

She could just be worn out but since you said she isn't very responsive, I would recommend to take her to the vet. The vet may want to run some blood work on her to ensure she didn't get into any toxins or poison while she was missing. They will also be sure she is well hydrated and doesn't need any additional treatment. I hope this helps and she starts to feel better soon. I am so glad you found her.

Is my cat's tiredness and sleeping a side effect of a rabies vaccine?

Hi. Poor Sunny. I know it may seem abnormal, but it is common and normal to have a patient be quiet, lethargic, hide, skip a meal, and ecen be sore and whiny after a vaccine. Some vaccines affect patients more then others. I would not worry unless Sunny starts vlmiting, having excessive lethargy, hives, swelling, or trouble breathing. I would monitor and call your veterinarian if any further signs occur.
