A Smart, Practical Approach to Raising a Healthy Dog
Bringing home a puppy is one of life’s great joys. Chewed shoes and all. Along with vaccinations and training, proper parasite control is one of the most important steps in setting your puppy up for a strong, healthy future.
Intestinal parasites are extremely common in puppies — even those that appear perfectly healthy. A thoughtful, evidence-based deworming plan (not guesswork) is the right way to protect both your puppy and your family.
Why Puppies Commonly Have Worms
Most puppies are born with parasites or acquire them shortly after birth.
Common intestinal parasites include:
- Roundworms – often transmitted from mother to puppies before birth
- Hookworms – can be transmitted through nursing
- Whipworms – acquired from contaminated environments
- Coccidia & Giardia – protozoal parasites commonly seen in young dogs
Some of these parasites can also infect people, especially children. That’s one more reason we take this seriously.
The Importance of Fecal Testing Before Deworming
It may seem logical to “just give a dewormer,” but proper veterinary medicine means knowing what we’re treating.
Why fecal testing matters:
- Identifies the specific parasite present
Not all dewormers treat all parasites. Using the wrong medication may do nothing. - Prevents unnecessary medication use
Responsible medicine means treating based on evidence — not assumption. - Detects protozoal parasites
Giardia and Coccidia require completely different medications than standard dewormers. - Establishes a baseline
A negative fecal test after treatment confirms success.
At Country Care Veterinary Center, we strongly recommend a fecal exam at the first puppy visit — even if your breeder or shelter already “dewormed.”
Recommended Deworming Schedule for Puppies
While individual plans may vary slightly depending on risk and lifestyle, a traditional and effective schedule looks like this:
🐶 2 Weeks of Age
- First deworming (typically performed by breeder)
🐶 4 Weeks of Age
- Second deworming
🐶 6 Weeks of Age
- Third deworming
- First fecal exam if coming into veterinary care
🐶 8 Weeks of Age
- Repeat deworming
- Fecal test recommended
🐶 12 Weeks of Age
- Fecal recheck
- Additional treatment if needed
🐶 16 Weeks of Age
- Final puppy fecal test
- Transition to monthly heartworm prevention (which also controls common intestinal worms)
Why Multiple Treatments Are Necessary
Here’s the key: most dewormers only kill adult worms.
They do not kill immature larvae. Those larvae mature over the next couple of weeks — which is why we repeat treatments at set intervals.
This isn’t over-treatment. It’s completing the life-cycle break properly.
After 16 Weeks: What Happens Next?
Once your puppy completes their initial series:
- Fecal testing is recommended at least annually
- Monthly heartworm prevention continues to control common intestinal parasites
- Additional testing may be advised for:
- Dogs who frequent dog parks
- Hunting or farm dogs
- Puppies in daycare or boarding
- Dogs with diarrhea
Signs Your Puppy May Have Worms
Some puppies show no symptoms. Others may experience:
- Pot-bellied appearance
- Diarrhea
- Weight loss
- Vomiting
- Scooting
- Poor coat quality
But remember — absence of symptoms does not mean absence of parasites.
A Practical, Responsible Approach
Deworming is not about guessing. It’s about:
✔ Testing
✔ Targeted treatment
✔ Rechecking
✔ Ongoing prevention
Good preventive medicine today avoids bigger problems tomorrow.
