Let’s assume that you have adequately described CPV to your clients and you explain that Brooklyn will need to be vaccinated today (at 8 weeks of age), again at 11-12 weeks old, again at 15-16 weeks old, and once more at 19-20 weeks old. Your clients seem taken back. “Isn’t that a LOT?” they ask. “Why so many vaccines?" by UA CVM Professional Skills

Slowly maturating the immune system, so it will be ready once the mother’s protective protein is no longer active in the puppy

We want to ensure Brooklyn is fully protected against everything in the environment. And this will ensure she gets full coverage without the possibility of infection. It does seem like a lot, but this is what has been proven to work.

Mom's antibody's are still in the puppies system, and as the puppy ages, the amount of antibodies goes down. The frequency of vaccination allows for the puppy to maintain the antibodies that were lost from mom.

Your pet is not fully protected with one vaccine, and this covers the risk window for when mom’s antibodies no longer protect the puppy. We want to keep her protected, safe, and healthy!

It may seem like a lot but they need the vaccines to fight against different diseases.

Currently her maternal antibodies are wearing off, and her immune system needs to be reintroduced to CPV in order to build immunity. Booster vaccines are required to ensure that there is enough protection

2026-06-15 23:27:53 UTC

This is the necessary schedule to ensure that Brooklyn will be covered/protected by these vaccines and that you are getting the most out of what you’re spending here today.

That’s a valid concern! It is best to see Brooklyn back every 4 weeks because many vaccines need boosters. This would ensure that she develops a proper immune response to keep her protected

2026-06-15 23:28:07 UTC

We want to ensure they have enough to adequately fight the virus. Since we cannot be exactly sure how much or how long the immunity from mom is, we want to make sure we protect her properly. It’s like teaching the immune system to walk you can’t do it in a day

2026-06-15 23:28:17 UTC

We want to expose your pet multiple times so that they have the best chance of building up their immunity. After these puppy vaccines, we can booster yearly

2026-06-15 23:28:37 UTC

The vaccine series will help the immune system slowly build the ability to better fight infections

They have maternal antibodies interfering so we need to wait until 16wks

There are many diseases out there

2026-06-15 23:30:32 UTC

We are training the immune system to identify and fight the virus. We don’t know the exact time that the mothers antibodies will fade so we want to make sure that the patient is protected by the vaccine to minimize the window of susceptibility.

Repeated exposure

2026-06-15 23:32:33 UTC

We want to Brooklyn to have a few chances to expose her system to different viruses. Her body needs to fight the virus a few times to know what to do if they ever experience the real virus.
