How does a dog get the shivers

Dogs get the shivers by a couple of things that include: coming from a freezing cold environment into a warm environment immediately, another way is if your dog is eating any toxic things like for example the waste of an other animal or possibly itself, if your dog is aged it might have the shivers by being close to death, if your dog has an injury at any part of the body then you should get it checked out because it just might be in pain which causes the shivers. There are plenty of other reasons that dogs can have the shivers so I would go to the vet and have them check your dog if it is still having shivers after 2 or more days. Some dogs end up having to just get a needle, and then they will be fine. If your dog still has the shivers after getting a needle then there might be something seriously wrong with your dog.
