My dog eats snails and slugs. How to prevent lungworm disease?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | unneutered | 5 months and 29 days old

I treat my dog with Advocate spot on flea and worm treatment every month, I noticed he has stated picking snails/slugs up from the garden and I'm worried about lung disease. Is there anything that can prevent this? I try to keep an eye on him in the garden but it's difficult, he's due his next treatment tomorrow. If there is a serious risk of him getting the disease by picking up snails/slugs can it be prevented through medication?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Ziggy loves the snails and slugs huh? Advocate is labeled to treat lungworms outside of the US. We have Advantage Multi and if I'm correct I don't think it's labeled for that here. So it appears that one of the active ingredients (imidacloprid or moxidectin) treats lungworms. Other than being a gross habit hopefully you won't see any problems with his odd taste in treats. It is possible that the medicine doesn't kill 100% of anything that it is labeled for so keep a close eye on him for coughing or other signs related to vomiting, diarrhea, etc. Good luck with Ziggy. Maybe he will grow out of this.
