What Happens If A Dog Gets Vaccinated Twice

What Happens If A Dog Gets Vaccinated Twice?

Your dog deserves to live healthy and strong, it’s not a privilege it is a right! However, it is important to know just how much care and vaccination is too much. Many have put man’s best friend in harm’s way all in a quest to remove them from the same.

This is why a lot of people wonder what happens if a dog gets vaccinated twice. The answer is not a direct one as there are a few factors that go into this situation and I believe by the time you follow me on this journey, you should be clearer as regards what to do.

What happens if a dog gets vaccinated twice?

Vaccinating your dog twice is certainly not an ideal thing to do even though it may not have any telling effects.  I’ve witnessed such situations before and more often than not, there are no telling side effects, however, it is advisable you keep a close watch on the dog per time. In the event of an allergic reaction, it usually occurs within 24 hours. It is, however, more of a concern when dealing with smaller dogs such as Yorkies or Chihuahuas because it may lead to an overload of their immune systems, hence the need to spread them apart.

If you have a puppy, keep in your mind that they require booster dosages once a month for four sessions.

What Are The Symptoms Of The Side Effects Of Vaccinations?

Before I shed light on this, I want you to know that the benefits of vaccinating your dogs far outweigh whatever risks that may arise. 

That, however, does not take away the possibility of side effects arising.  It is therefore advisable to vaccinate your dogs at a time when you feel you can closely monitor them.

If you have vaccinated your dog and still observe any of these symptoms, take him to the vet for a checkup.

  • Vomiting
  • Fever
  • Slowness
  • Swelling and pain of the part injected
  • Difficulty breathing as well as seizures

However, as in the case with humans, you may choose to ignore mild signs. Usually, the symptoms outlined are mild and don’t last long.

If you, however, feel the signs are more than usual, you may have to consult your veterinary doctor right away.

What Makes Vaccinating Your Dog So Important?

When the use of a thing is not fully known, abuse is certainly inevitable. Vaccines assist in prepping a dog’s immune system to defend them.

The vaccines are made up of antigens that imitate the disease organisms causing (non-problematic) diseases in the dog’s system.

What vaccines do is trigger the dogs’ immune system by making it identify the present antigens.

What this means is that when the dog is exposed to the main disease, their bodies will detect and face it.

How Do I Recognize The Core Vaccination For My Dog?

Let me start by saying vaccines are divided into two categories namely the core and non-core vaccines for the core vaccines we have a Hepatitis vaccine, Canine Parvovirus, and rabies.

For the non-core vaccines, we have Lyme Vaccine, Bordetella, Canine Influenza, and leptospirosis.

Even though some of the aforementioned vaccines may not be considered core vaccines, they are quite crucial for dogs that may have been exposed to several diseases.

What Are Vaccine-Induced Diseases?

One of the greatest challenges facing the health of dogs is the seeming focus on diseases; this has made vaccines to be rather counterproductive.

One of the major issues that arise from the use of vaccines is referred to as Vaccinosis.

What Does Vaccinosis Mean?

Vaccinosis stands for the symptoms that arise as a result of vaccine administration.

Some of these symptoms may be identified within a short period while others may take even years before they manifest. 

Although Vaccinosis is not a recognized disease, it puts the body in a state of dis-ease.

What Are The Main Symptoms Of Vaccinosis?

The symptoms of this condition range from a little too critical such as chronic anxiety. 

There are other symptoms such as seizures,  and death, which makes this terrible is that most of the chronic issues that arise may not be easy to trace back to the vaccine.

How Can You Avoid over-vaccinating Your Dog?

Vaccines are good especially when they are administered the right way. The big challenge in this situation is that you must be prepared with the right amount of information as regards what should and should not be done per time.

Basically, anyone can over-vaccinate a dog knowingly or unknowingly, but in the end.  Here are a few things to keep at the back of your mind as you vaccinate your dog.

Always Keep a dog vaccine record book or Record Card

Be equipped with your dog’s vaccination history

Taking your dog for checks only once in three years may not be the best strategy, you must take them for yearly checks. Instead of you throwing the doctor’s card away, keep it handy for the next check.

Yearly checkups assist the veterinary doctors to have a better understanding of your dog’s health. It should also help them to be able to notice changes in the health of your dog at times.

It is interesting to note that it is during these annual trips to your veterinary doctor that the issue of vaccination usually pops up. And even with our best intentions, most of us head to Vets office without knowing what to expect.

  • Space also provided to record worming dates.
  • Pkg of 10.

A lot of times, we get rather confusing recommendations of a long list of vaccines to use. It’s quite funny that several people simply agree to the recommendations of the vet even without full knowledge of the consequences.

I, however, advise pet owners to be prepared for embarking on that trip to the vet clinic. By preparation, I don’t mean just remembering things such as your dog’s collar, leash, and treats.

It is even beyond remembering the scheduled day and time or going along with the right dog. What then should be the most important thing to take along you may ask?

The answer to the aforementioned question is pretty straightforward; ensure you go along with the record and list of its history.

It is not in your best interest to assume that the vet clinic will be up to date in its records.

Having a record that indicates antibody test results, heartworm tests urinalysis test results, and the like with their dates is a good way to go.

I would recommend that you come up with a simple table that indicates the vaccines against the dates.

If you are however going to a new clinic, chances are high that they may request proof of your summary, hence you should go along with records from the previous vet.

There are a few other things you should be mindful of in this regard such as the following:

  • Be sure of what you want for your dog in terms of vaccinations while also ensuring you have a fair idea of what each vaccine is meant for. In a case where you are not sure, have a good understanding of the vaccines that are available and make sure to confirm from your vet if any of the vaccines are warranted as a result of conditions in your location.
  • Get more knowledge so you don’t always have to feel dumb when conversing with your vet on the different cons and pros of vaccinating your pet. Search for pet blogs and websites where you can get loads of relevant information.
  • Ensure to be in the loop concerning your dog’s health status so that you can be sure if it has any health issues you should know of.
  • You should be aware of what a visit to the vet would cost you to avoid any surprise or a situation where you may make decisions based on your pocket strength.
  • Never be scared to take your dog home if you are not comfortable with what you vet may be saying. You do not need to be in a hurry with making decisions. You can always politely let the vet know your stance on such matters.


Your dog deserves a good life regardless of the inherent cost.  However, in your quest to give your dog the best life, don’t be so overzealous that you vaccinate it twice.

As I pointed out earlier, the implications of such an action may not be pronounced, but it does leave behind a few negative effects.

It is therefore advisable that you have proper records of your dog’s health history to avoid such.
