Side Effects of Canine Distemper Vaccine

Distemper is a very contagious viral disease that dogs can contract. Besides dogs, cats and wild animals like foxes, raccoons and skunks and also contract it. Once an animal gets distemper, it is invariably fatal.

The virus that causes the disease adversely affects the respiratory system, the gastrointestinal system and the nervous system of the dog. It usually affects the respiratory system first. That is why it is imperative that dog owners vaccinate their pets against this disease.

Dogs are vaccinated against distemper between the ages of four weeks and twenty weeks. Although this vaccination is a living saving one, it also has some side effects. However, not all dogs show the side effects of the vaccine.

Here are some side effects of distemper vaccine that are commonly seen in dogs:
Usually pups after being given the vaccine end up feeling lethargic. They may just lie and appear as though they are exhausted. Usually this lethargy lasts for around 2 to 3 days. It is quite common for pups to also get mild fever. Although it is nothing to get worried about, you should immediately rush your puppy to the vet if the fever increases.

The injection site may get swollen. In fact, invariably a lump forms, but it disappears in a day or so. However, if the face of the pups is swollen after receiving the vaccination, you should immediately take your pup to the vet.

Many pups are known to lose their appetite after receiving the distemper shot. This, in turn, causes weight loss as well as temporary weakness. At times diarrhea or vomiting might ensue. In case the puppy is not drinking any water or eating food, you will have to take it to the vet to prevent onset of dehydration.

While the above mentioned side effects are rather mild and not life threatening, some of the side effects can be dangerous and fatal. One such side effect is an allergic reaction. Here your puppy may start vomiting, suffering from diarrhea, get hives, have low blood pressure, and also have a fast heart beat. In case the throat swells, the puppy may find it difficult to breathe. Usually the reaction will appear immediately after the puppy receives the shot. However, at times, it can take as long as twenty-four hours to develop. Either way, your pup needs immediate medical attention or it can die.
