Why Do Puppies Sometimes Develop Parasites or Upset Stomachs After Going Home?


Bringing a puppy home is exciting — and sometimes surprising.  One of the most misunderstood realities of puppy ownership is this:

✔️Even when breeders follow excellent protocols, puppies can still experience…
●parasites
●loose stools, or
●tummy changes
shortly after arriving in their new home.

Not because the breeder failed — but because stress changes biology.


✔️The Puppy Immune System Is Still Developing

Like toddlers, puppies experience and adapt to the world through exposure.

That means:
●their gut microbiome is still forming
●they shed what no longer serves them
●they pick up what they come into contact with

This is normal, not a defect.


✔️The Change of Environment Is a Trigger…
●new home
●new people
●new food
●new routines
●new water
●new bacteria
●new stressors

Even good stress (love, excitement, learning) can temporarily lower immunity and activate organisms that were previously dormant.


✔️Parasites Often Live Quietly Until Stress Activates Them

Conditions like…
●coccidia
●giardia
●roundworms
●hookworms
can be present in very small, inactive quantities that don’t show on tests and produce no symptoms — until immunity dips.

✔️This Does NOT Mean:

🚫 the breeder didn’t treat
🚫 the breeder is dirty
🚫 the breeder lied
🚫 the puppy was sick before

It means the puppy transitioned — and nature took its course.


✔️What We Do Before Puppies Leave…

●apply protocols set by our veterinarian
●give two Neopar Parvo Boosters before going home
●follow a preventative parasite schedule
●have a veterinary examination with 1st vaccinations
●send puppies home at 9-10 weeks old
●if 2nd and 3rd vaccinations are due while a puppy remains with us, we purchase from our vet and administer ourselves
●we continue vet care when necessary
●have our vet administer a microchip
●send all records home with puppy
●continue education for buyers


✔️What You Can Expect as a New Puppy Owner

Almost all puppies will, at some point, experience:
●diarrhea or soft stools
●a brief appetite change
●a parasite that requires treatment

This is why it’s important to maintain:
●communication with your breeder
●established veterinary support
●a calm environment
●proper sanitation
●not switching foods too quickly


✔️The Loving Truth

A healthy puppy isn’t one who never experiences anything — it is one who:
●develops immunity
●adapts
●recovers
●learns resilience

And breeders who tell you it “never happens” — usually don’t say it publicly because they fear being judged.


✔️Your Role in Supporting Their Health
✅️schedule your new puppy exam when retainer is made
✅️follow treatment recommendations
✅️notify us if symptoms arise
✅️understand this is a normal part of development

We are here to help you succeed — together.


🤎 Final Thought

Transparency shouldn’t be punished — it should be valued.

When breeders AND families understand this reality, we replace shame with partnership and fear with teamwork.

Your puppy is not defective —
🤎they are growing,
🤎exposed to the world, and
🤎learning how to thrive.
