Deworming a dog: how to recognize the signs of infestation?
Deworming a dog is essential to preserve its digestive and general health. Yet, many owners wait for visible symptoms to appear before acting. However, internal parasites such as intestinal worms can remain discreet for several weeks.
Thus, recognizing early signs helps avoid complications. In this article, you will discover the 10 key symptoms that should alert you and prompt you to deworm your dog quickly.
The signs that should alert you

Why is deworming a dog important for its health?
Digestive worms directly impact the digestive system. However, they can also weaken the immune system. As a result, an infested dog becomes more vulnerable to infections.
Moreover, some parasites are transmissible to humans. It is therefore essential to adopt regular deworming, even in the absence of visible symptoms.
Causes, symptoms, or related concerns
Here are the 10 symptoms to watch closely:
- Unexplained weight loss despite a normal appetite
- Swollen belly, especially in puppies
- Frequent diarrhea or soft stools
- Regular vomiting
- Presence of worms in stools or around the anus
- Anal itching (dog rubbing itself on the ground)
- Dull coat in poor condition
- Unusual fatigue or decreased energy
- Increased or decreased appetite
- Growth delay in puppies
In some cases, symptoms remain subtle. However, even a dog that looks healthy can be infested. This is why regular prevention remains essential.

Frequently asked questions about dog dewormer
How often should you deworm a dog?
The deworming schedule depends on the dog's age, lifestyle and parasitic risk. It should be defined with the veterinarian; puppies require a program adapted to their development. Depending on the situation, stool tests may supplement monitoring or guide treatment. Do not automatically transpose the schedule from another animal. Check the ESCCAP guidelines on individual deworming.
Can you deworm a dog without symptoms?
Yes, and it is even recommended. Indeed, internal parasites can remain invisible for a long time. Preventive deworming avoids digestive complications and contaminations.
Are dog worms transmissible to humans?
Some worms, such as roundworms, can be transmitted to humans. Children are particularly exposed. Deworming a dog therefore also protects the whole family.
How do you know if the dewormer was effective?
After administration, worms may appear in the stools. However, their absence does not mean the treatment has failed. The treatment often works invisibly but effectively.
