If your dog recently ate a slug, you may be worried about whether it will cause any health issues. Slugs can potentially carry parasites that could make dogs sick, but in most cases there is little cause for concern as long as it was just a one-time occurrence.
What are the risks of dogs eating slugs?
The biggest risk from dogs eating slugs or snails comes from the potential exposure to parasitic worms known as lungworms or helminths. Lungworm larvae can be carried by slugs and snails, and if a dog accidentally eats an infected slug, the larvae can then mature inside the dog and cause a lungworm infection.
Lungworm infections are relatively rare in dogs, but when they do occur they can potentially lead to coughing, breathing difficulties, bleeding issues, heart problems, and pneumonia in severe cases. So lungworms are the main health concern to be aware of if your dog ate a slug.
What are the chances my dog will get sick?
While lungworm infection is possible, the actual chances of your dog becoming ill from eating a slug are quite low. Here are a few reasons the risk is limited:
- Not all slugs and snails carry lungworm – even in areas where lungworm is common, only around 20% of slugs are typically infected.
- Dogs need to eat infected slugs raw to be exposed – cooked or partially digested slugs will not transmit the parasite.
- A single slug is unlikely to have a high enough larvae count to cause infection.
- Most healthy dogs are able to fight off small amounts of larvae before they mature and cause issues.
So while eating slugs and snails does introduce some level of risk, a single incident is very unlikely to make your dog sick in most cases.
Are certain dogs at higher risk?
Puppies under 6 months old, as well as pregnant and nursing dogs, may be at higher risk for developing a lungworm infection. This is because their immune systems are not yet fully developed, making it harder for them to fight off larvae exposure.
Dogs with other health issues like diabetes, kidney disease, or cancer also have increased susceptibility to lungworms. If your dog falls into one of these higher risk categories, it’s a good idea to contact your vet for advice if they ate a slug.
What symptoms should I watch for?
If your dog did ingest a substantial amount of slugs, it’s a good idea to monitor them carefully over the following weeks for any signs of illness. Contact your vet immediately if you notice any of the following symptoms, as they could indicate a lungworm infection:
- Coughing
- Gagging or breathing difficulties
- Lethargy
- Loss of appetite
- Weight loss
- Bleeding issues – bloody urine, stool, vomit, or nosebleeds
- Neurological issues – wobbliness, circling, seizures
You should also watch for symptoms of gastrointestinal upset like vomiting or diarrhea, as slugs can sometimes carry other parasites and bacteria that may cause these issues.
How is lungworm infection diagnosed and treated?
If you suspect your dog may have a slug-related illness, the vet will start by considering any potential exposure to slugs/snails along with your dog’s vaccination history. They can then run various diagnostic tests such as:
- Fecal exam – Checks for lungworm larvae in your dog’s stool.
- Blood test – Checks for antibodies against lungworms.
- Chest x-rays – Helps identify lung inflammation and abnormalities.
- Bronchoscopy – Uses a tiny camera inserted into airways to inspect lungs directly.
Once diagnosed, lungworm is treatable. The most common medications prescribed are:
- Fenbendazole – Antiparasitic medication that kills larval and adult lungworms.
- Milbemycin – Another deworming medication that also prevents heartworm.
- Moxidectin – Kills lungworm larvae before they develop into adults.
These drugs are usually given daily for 1-2 weeks to treat active infections. In mild cases, symptoms improve quickly with treatment, but more severe infections can take longer to resolve and may need extensive supportive care.
How can I prevent this in the future?
Here are some tips to protect your dog from slugs/snails going forward:
- Use slug and snail bait around your yard to control populations.
- Clear any slug/snail hiding spots like tall grass, piles of debris, or mulch around your property.
- Consider a mesh barrier around your fence line to prevent slugs from entering your yard.
- Pick up any slugs or snails you notice in your garden and discard them.
- Supervise your dog when outside, especially in damp/overgrown areas.
- Train your dog to avoid eating slugs and snails.
- Ask your vet about lungworm prevention medications.
Prevention is the best approach to avoid lungworm infection in dogs. But even with precautions, the occasional slug or snail encounter is unlikely to make your dog sick.
Will my dog recover completely?
The prognosis for dogs with lungworm infection is generally very good with prompt treatment. Most dogs make a full recovery and do not experience any long-term effects.
In cases where significant lung inflammation, bleeding, or secondary pneumonia occurs, it may take some extra time for your dog to fully bounce back. But with supportive veterinary care, complete recovery is expected in otherwise healthy dogs.
Young puppies are more prone to complications from heavy parasite burdens, and may need close monitoring. But again, with proper treatment the vast majority will recover without issues.
Key Takeaways
- Lungworm infection is the main health concern when dogs eat slugs and snails.
- The risk from a single incident is very low in most healthy adult dogs.
- Monitor for coughing, breathing issues, bleeding, diarrhea in the weeks after exposure.
- Contact your vet right away if any symptoms develop.
- Lungworm is very treatable, and most dogs recover fully with prompt care.
The Bottom Line
While slugs and snails have the potential to transmit parasites, dogs are unlikely to become seriously ill from eating the occasional slug. Monitor for concerning symptoms over the next few weeks, but in most cases you can rest assured your dog will be just fine. Use common sense precautions to avoid exposure going forward.
If you have any concerns about possible slug/snail ingestion, always reach out to your vet for guidance. With prompt treatment if needed, the prognosis is excellent for a full recovery.

If your dog ate a slug, seek immediate veterinary attention if any concerning symptoms develop. But in most cases, there is no cause for major concern and your dog will remain perfectly healthy.
