How old does a puppy have to be so it get parvo without shots?

It's important to understand that puppies are not born immune to parvovirus. They are highly susceptible to the disease, which can be fatal.

Here's the breakdown:

* Puppies are vulnerable to parvovirus from the moment they are born. Their immune systems are not yet developed enough to fight off the virus.

* The risk of parvovirus infection is highest between 6 and 20 weeks of age. This is because their maternal antibodies (passed from the mother) begin to wane, and they haven't yet built up their own immunity through vaccinations.

* Even after vaccination, puppies are not fully protected until they have completed the entire series. This typically involves a series of three shots, with the final one administered around 16 weeks of age.

It's critical to:

* Vaccinate your puppy against parvovirus as soon as possible. Your veterinarian will recommend the appropriate vaccination schedule for your puppy based on their age and health status.

* Keep your puppy away from other unvaccinated dogs. This includes public parks, dog parks, and areas where other dogs may have been.

* Practice good hygiene. Wash your hands frequently and avoid touching your puppy's mouth or nose after handling other dogs.

Parvovirus is a serious disease that can be fatal. It's crucial to take all necessary precautions to protect your puppy. Consult your veterinarian for more information and guidance on preventing parvovirus.
