Parasites
Parasites in Dogs
Not all dogs have the same risk
Fleas, ticks, worms, and other parasites are a part of dog life, but the risk isn’t the same for all dogs.
Where your dog spends its time, what it eats, whether it travels abroad, and which parasites are present in the local area all influence our recommendations.
In Zealand, there are two parasites we pay extra attention to: heartworm/lungworm and Giardia.
We Take Heartworm and Lungworm Seriously
In Zealand, we regularly see infections with French heartworm and lungworm.
Snails act as intermediate hosts, so dogs can become infected through contact with snails or snail material.
Infection with French heartworm may initially show no clear symptoms.
Look out for, among other things
- coughing
- reduced stamina
- fatigue
- breathing problems
- bleeding tendencies
- weight loss
However, because symptoms can be non-specific – and some dogs don’t show clear signs early on – a fecal examination may be relevant.
Three Samples Provide a Better Picture
When testing for heartworm and lungworm, we recommend fecal samples from three consecutive days.
This is because larvae are not necessarily shed in the same quantity every day. By examining samples from multiple days, we increase the likelihood of detecting an infection.
You can pick up a collection kit from us at the clinic.
Giardia
Giardia is a microscopic intestinal parasite that can cause stomach and intestinal problems.
It is especially common in younger dogs and in environments where many dogs are in close contact.
Symptoms can vary, but diarrhea – often recurring or fluctuating in consistency – is typically something that makes us consider Giardia.
If we suspect Giardia, a fecal sample may be part of the diagnostic process.
What About Fleas and Ticks?
The risk of fleas and ticks depends on factors such as the season, environment, and your dog’s lifestyle.
There are various options for prevention and treatment, and we are happy to help assess what makes sense for your dog.
Is Your Dog Traveling on Vacation?
When dogs travel abroad, they can be exposed to parasites that we don’t normally see – or see less frequently – in Denmark.
The relevant protection depends on factors such as the destination and the nature of the trip.
Additionally, there may be legal requirements for treatment against certain parasites upon entry into some countries.
Should Your Dog Be Tested for Parasites?
If you are unsure about symptoms, risk of infection, or the need for a fecal sample, we are happy to help assess what makes sense for your dog.
If testing for heartworm and lungworm is needed, you can pick up a collection kit at the clinic.
