Lungworm Test for Dogs

Further information

Our Dog Lungworm Test provides extended laboratory screening for canine respiratory and nasal parasites using specialist faecal testing methods.

To do this, our laboratory team examines faecal samples for relevant larvae and eggs associated with five parasite targets. As a result, this screening supports a test-led approach to lungworm monitoring and helps you make informed decisions about your dog’s health.

What does the Dog Lungworm Test include?

Our extended lungworm screen covers the following parasites:

  • Angiostrongylus vasorum – French heartworm.
  • Crenosoma vulpis – fox lungworm.
  • Oslerus osleri – tracheal lungworm.
  • Filaroides hirthi – pulmonary lungworm.
  • Eucoleus spp. – respiratory and nasal capillarids.

Who is this test suitable for?

Lungworm screening can be particularly useful for dogs with increased exposure risks. For example, we recommend considering this test for:

  • Dogs that spend significant time outdoors.
  • Dogs that may encounter slugs or snails.
  • Dogs that hunt, scavenge or explore areas frequented by wildlife.
  • Dogs with a previous history of lungworm infection.
  • Owners who want to include lungworm monitoring in a regular parasite screening programme.

How does the testing process work?

Each kit includes clear instructions and the materials needed to collect and return your dog’s faecal samples to our laboratory.

Collect small faecal samples over three consecutive days. This is essential because parasite larvae and eggs may be shed intermittently. Therefore, samples collected over all three days are required for the lungworm screen.

During collection, keep the lungworm samples in a cool place. Do not refrigerate or freeze them.

Once your samples arrive, our trained laboratory team carries out the appropriate screening procedures. We then email your results on the next working day following arrival at our laboratory.

In addition, every Dog Lungworm Test includes a clear laboratory report and free after-test advice where required.

Looking for gastrointestinal worm screening too?

If you would also like to screen for gastrointestinal worms, our Combined Worm Count and Lungworm Test for Dogs includes both screens in one convenient package. This provides broader parasite screening while keeping the sample collection process straightforward.

Our Dog Lungworm Test is an extended faecal screen for respiratory and nasal parasites in dogs.

Extended Canine Lungworm Screen

Our trained laboratory team uses specialist methods to examine the submitted faecal sample for lungworm larvae and relevant parasite eggs.

The screen covers the five canine respiratory parasite targets listed in the results section. A routine gastrointestinal worm count does not replace this specialist screen.

Sample Collection

Collect faecal samples over three consecutive days. This is essential for the lungworm screen because parasite shedding can be intermittent.

Laboratory Reporting

Our team reviews the findings before emailing a clear report. Free after-test advice is available where required.

We report whether lungworm larvae or relevant parasite eggs were detected in the submitted faecal sample.

Extended Lungworm Screen Results

Our extended canine lungworm screen uses specialist laboratory methods to look for respiratory and nasal parasites that may shed larvae or eggs in faeces. The screen includes:

  • Angiostrongylus vasorum – French heartworm.
  • Crenosoma vulpis – fox lungworm.
  • Oslerus osleri – tracheal lungworm.
  • Filaroides hirthi – pulmonary lungworm.
  • Eucoleus spp. – respiratory and nasal capillarids.

We report whether relevant larvae or eggs were detected and, where appropriate, identify the parasite and assess the findings.

Lungworm larvae and eggs may be shed intermittently. Faecal samples collected over three consecutive days are essential for this screening procedure.

Understanding Your Results

Where appropriate, we provide parasite identification and an assessment of the findings. If we detect no parasites above the detectable limits, we state this clearly.

Please note: Lungworm shedding can be intermittent, so a negative result does not completely exclude infection. If your dog has concerning symptoms, please consult your veterinary surgeon.

Your report is emailed to you, and free after-test advice is available where required.

Turnaround time: We issue lungworm results on the next working day following arrival at our laboratory.

Lungworm sample collection: Collect faecal samples over three consecutive days. This is an essential requirement for the lungworm screen. Keep samples in a cool place. Do not refrigerate or freeze lungworm samples.

After treatment: If you are using the test as a post-treatment check, we generally recommend retesting around three weeks after treatment.

Results: We email your report once the laboratory examination and review are complete.

Your kit includes the materials needed to collect and return your faecal sample(s) to our laboratory:

  • A recyclable padded return envelope with prepaid Tracked 24 return postage.
  • Laboratory request forms and clear sample collection instructions.
  • Recyclable sample collection containers and resealable write-on bag(s).
  • Biodegradable secondary sealable bagS.
  • Biodegradable natural wood sampling spoon.

Each kit is for one dog. Please follow the sample collection instructions supplied.
