Deworming your dog: why deworming is essential all year round
Deworming your dog is an essential step in maintaining their digestive health. Intestinal parasites are common in dogs, even without visible symptoms.
Digestive worms can cause:
- digestive disorders
- weight loss
- growth delay
- fatigue
- reduced immunity
In addition, some parasites can be transmitted to humans. This is known as zoonoses. Deworming therefore also protects your family.
Dogs are easily contaminated during walks. They can swallow parasite eggs present in the environment.
Thus, following a deworming schedule remains essential all year round.
Deworming your dog: what frequency according to age and lifestyle?
Why is it important to deworm your dog regularly for their health?
Digestive parasites can remain invisible for a long time. However, they progressively weaken the body.
Regular deworming helps:
- protect digestion
- prevent complications
- support the puppy's growth
- limit environmental contamination
- reduce zoonotic risks
The protocol must be adapted to each situation.
Causes, symptoms and issues associated with parasitic infestations
Dogs can become infested in many situations:
- ingestion of contaminated grass
- contact with faeces
- ingestion of prey
- presence of fleas
- maternal transmission in puppies
Certain signs should raise concern:
- diarrhoea
- vomiting
- bloated abdomen
- anal itching
- unusual fatigue
- dull coat
However, the absence of symptoms does not mean the absence of parasites.
Recommended veterinary solutions to effectively deworm your dog
The frequency mainly depends on the dog's age.
In puppies
- every 15 days until 2 months old
- then once a month until 6 months old
A puppy can be contaminated before birth. Early deworming remains essential.

An adult dog must be dewormed at least every 3 months.
However, some dogs require a higher frequency:
- dogs living with children
- hunting dogs
- dogs living in groups
- dogs living in rural areas
In these situations, deworming every 2 months is recommended.

An adult dog must be dewormed at least every three months. However, a dog living with children or regularly exposed to the outdoor environment may need more frequent deworming to limit parasitic risks.

Yes. Most parasitic infestations remain invisible for several weeks. Deworming your dog regularly helps avoid digestive complications and reduces the risk of transmission to humans.

What is the best time to deworm your dog?
The dewormer can be given in the morning, often on an empty stomach depending on the product used. However, some tablets can be given with food. It therefore remains important to follow the manufacturer's or veterinarian's recommendations.
