My puppy is acting strange after rabies vaccine. Is it a reaction?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Male | unneutered | 3 months and 5 days old | 22 lbs

Chief had his third set of injections today which included his first rabies vaccine. He is acting very strange, he runs away from me, hasnt slept for quite a while, has been panting amd crying a lot and has been roaming the garden by himself as if he is looking for something. I am a little bit concerned as he is never like this. Thanks in Advance:)

Chief may be having a vaccine reaction or may just be having pain from the vaccine. I recommend to call your veterinarian and let them know what is happening. They may ask to see him again or they may have you give him an antihistamine. I hope he feels better quickly and please feel free to post any additional questions.
