Menthol vs. Nicotine

There is no information available on the toxicity of e-cigarette capsules with menthol flavors, but the menthol part of the cartridge is not very toxic, unlike the nicotine which we know is very dangerous to your pets. Like all toxins, it is dose-related, so a small amount for a big dog is not as significant as a large amount for a small dog.

Sugar vs. Xylitol

If you are talking about a puppy eating a peppermint or menthol cough drop, the main reason I would be worried is that the candy might be "diet" and have xylitol instead of sugar. Xylitol can kill your dog, whereas the menthol will just make him a little nauseous and may even cause him to vomit.

The Bottom Line

The toxic dose is so high that the only way menthol could kill your dog is if it were vaporized and pumped into the lungs.

Menthol e-cigarettes, however, may kill your dog through nicotine poisoning, so keep them out of reach of your dog or, better yet, just stop using them.
