Do dogs shiver after getting shots?

Dogs might shiver after receiving shots due to the body's natural response to the vaccine. Vaccines may cause a mild immune response in dogs, which occasionally results in temporary side effects such as fever, shivering, or lethargy. These side effects are typically mild and go away within 24-48 hours. Some dogs may also shiver from the stress of being at the vet or receiving an injection. If you're concerned about your dog's shivering, talk to your veterinarian.
