What Vaccinations Must A Puppy Have Before They Sell?

And here are also the frequently asked questions about dog vaccinations.


What kind of vaccines must dogs have before they sell? 

Since most states have the regulation for the minimum age of a puppy to be sold at 8 weeks, that means the puppy has been vaccinated for Parvovirus, Distemper and Adenovirus (Hepatitis).

What if I don’t know if my dog has been vaccinated?

Reputable breeders can give you detailed information about the vaccines that have been shot to their dogs. But in case you are unsure, you can consult your vet to run a blood test to measure your dog’s antibodies.

Why do dogs need vaccinations? 

Vaccinations are important for dogs to protect them against deadly diseases since each injection contains several vaccines for several different diseases.

Since vaccinations are important for dogs, make sure to ask the question to the breeder of the dog you want to buy from whether the puppy you want has been shot, and what kind of vaccines the puppy has been shot. 

Is it illegal to sell a puppy before vaccinations?

In some states, people who want to sell their puppies need to vaccinate their dogs prior to offering them for sale. This is one of the dog laws in Florida

And here are some requested vaccinations: 

  • Canine distemper
  • Leptospirosis
  • Bordetella
  • Parainfluenza
  • Hepatitis
  • Canine parvo
  • Rabies
  • Roundworms
  • Hookworms

So if you are living in a state that has a regulation for dog vaccinations, you should ask the breed or seller for a copy of the vaccinations according to the law, and then follow up with your veterinarian for the next vaccines. 

How long do Puppy vaccines last?


Once you receive your adorable puppy you want from the breeder or seller, and the puppy you buy has been shot for vaccinations, you probably wonder if your puppy needs more vaccines or is it enough for your puppy to get vaccines from the breeder? 

Well, the answer depends on what kind of vaccines your puppy has been shot before while he/she was in the breeder’s hand. 

Core vaccines are mostly given to a puppy once he/she is at 52 weeks, and he keeps being injected every 3 years for revaccination and rabies. 

And for non-core vaccines, some people might skip that part, though it’s still recommended for a puppy to get non-core vaccines, especially Bordatella, Leptospirosis and Lyme Disease.

Once your puppy is vaccinated, you don’t need to revaccinate the same vaccines. Getting more vaccines for your puppy doesn’t mean it’s better. Immunity induced by vaccination is extremely long-lasting and, in most cases, lifelong.


It is important for dogs to get vaccinations to improve their immunity and also to protect them against deadly diseases. 

Once you decide to buy a puppy, make sure to ask the breeder or seller whether the puppy has been vaccinated before and what kind of vaccines that the puppy has been given. 

Also by asking whether the puppy has been vaccinated, you know the breeder is reputable or not since a reputable breeder will take care of their puppy’s health including giving the vaccinations to their puppies. 

And lastly, don’t forget to ask for a copy of the puppy’s vaccinations from the breeder, so you can consult your veterinarian to determine what and when the next vaccine is due.
