Can Unvaccinated Puppies be Around Vaccinated Dogs? [are vaccinations bad for dogs?]
Pet owners may wonder if there is a risk when you have an unvaccinated puppy around a vaccinated dog? Is there a chance the unvaccinated puppy will get sick? The answer is yes, they can.
Since the early 1900’s the medical profession has been using vaccines on dogs to prevent them from getting Bordetella Bronchiseptica, Canine Distemper, Canine Parvovirus (parvo), Infectious Canine Hepatitis, Rabies, Lyme disease, and other illnesses.

Are Puppies Born With Natural Protection From Diseases?
There is something called maternal antibodies that puppies get from their mother while they are still in the womb. It can last up to around three months or so after birth and it helps protect the puppy against diseases.
This will help protect the puppy from diseases for several months to maybe a little longer depending on the individual dog.
Puppies Immune System
At some point though, usually by the 16th week, there are no protective antibodies left from the puppy’s mother in their bloodstream.

So yes, you could have a vaccinated dog around an unvaccinated puppy and they may not get sick. But your young dog’s immune system is not perfect.
It’s possible that if given enough exposure to an infected dog while being unprotected themselves, your puppies may catch something.
When Should Puppies Get Their First Shots?
New puppy owners should contact their vet right away for recommendations on puppy vaccinations. In general, vets usually start the first round of vaccinations at six to eight weeks of age.
They will probably set up a puppy vaccination schedule for you with a recommended series of shots that take place during the first year of the puppy’s life.

NOTE: Keep in mind that if you purchased your puppy from a breeder or you adopted from an animal shelter they may have already gotten some or all of their needed shots.
Make sure you ask and also get a copy of any existing medical records for your new pup!
What Types of Shots Should My Puppy Get?
There is a large variety of shots your veterinarian may recommend for your new puppy. In general, every dog will not need to be immunized against all possible ailments.
Your vet will customize your puppies shot regiment based on several factors including:
- Age of your dog
- Their living environment
- Any health issues they may have
- If they will be traveling and to where
- How often they are exposed to other dogs
How Much Do Puppy Shots Cost?
The cost of shots for your puppy’s first year of life can vary by where you live and where you get the shots. If a shelter administers the shots it is usually much less expensive.

In general, first-year puppy shots can cost between $100 and $200 based on a survey of several vets we called.
How Long Do Puppy Shots Stay Effective?
Most puppy shots will be effective for about a year but it can vary based on what the shot is for.
Remember, an adult dog needs the protection of a vaccination to help fight off diseases.
How Do I Know If My Dog Needs to Be Re-Vaccinated?
Always consult your vet for specific guidance concerning how often your dog should get immunizations.
There are differing opinions about how often a dog should be vaccinated throughout its life.
What are the Risks for Unvaccinated Puppies When in Contact with a Vaccinated Dog?
The key here is the word ‘vaccinated’ and what that means to different dog owners.
Since it is very difficult to really know if a dog has been fully vaccinated (and when) by simply asking the dog’s owner it is better to err on the side of caution.
Contact your vet and ask but it makes sense to just keep your healthy puppy away from other dogs until they are fully vaccinated and protected.
Ways to Protect an Unvaccinated Puppy
The risk of catching something from another dog will be lower if:
- The other dog has been completely vaccinated for more than two weeks.
- Your dog does not come in direct contact with the other dog (is that even possible?)
- The two dogs stay more than five feet apart at all times.
- Don’t let the two dogs play with each other. Avoid public places.
- Don’t take your unvaccinated puppy to dog parks, doggie daycare, or boarding kennels.
- Avoid unvaccinated dogs of all ages
Is It Healthy For a New Puppy to Be Sheltered from Other Animals?
This is a great question! There is always a risk versus reward type of scenario.
While your natural instinct is to protect your puppies’ health, the American Veterinary Society of Animal Behavior has published some interesting information on this very topic!
They point out that the most important time of a dog’s life is the first three months as far as socialization goes.
Behavioral problems are the greatest threat to the owner-dog bond. In fact, behavioral problems are the number one cause of relinquishment to shelters.
Behavioral issues, not infectious diseases, are the number one cause of death for dogs under three years of age.
While puppies’ immune systems are still developing during these early months, the combination of maternal immunity, primary vaccination, and appropriate care makes the risk of infection relatively small compared to the chance of death from a behavior problem.

Definitely something to keep in mind! Again, ask your local vet for guidance.
