๐Ÿ“ Summary

Most bugs are harmless to dogs, but a few can cause real harm. Learn which insects are safe, which are dangerous, and what symptoms to watch for.

1 Overview

What do bugs mean to a dog?

Rest assured, most bugs are harmless and can even be an occasional, if unreliable, source of protein.

The odors inside a bug tell a dog what it just ate, so few dogs actually enjoy eating them.

Why dogs eat bugs

The main reason is curiosity, though some dogs simply like a certain bug’s texture or smell.

Which bugs can dogs not eat?

True, most are harmless, but a few can affect a dog’s health.

Which bugs are unsafe?

Any bug that contacts feces is dangerous. Cockroaches, dung beetles and the like can pass worms to your dog and burden its stomach.

Swallowing harmful bugs causes vomiting, diarrhea, drooling, weakness, and lethargy. Large amounts can cause abnormal heart rate, seizures, dilated pupils, even death.

Can dogs eat these bugs?

Ants

Yes, ants provide protein and are rich in vitamin C.

Common ants are fine, but if your dog eats fire ants, have it checked by a vet. They can sting the nose and mouth, just as they do in humans.

Beetles

Most beetles are safe for dogs.

But ladybugs may upset a dog’s stomach.

Cicadas

Dogs can get oddly hooked on cicadas, though no one knows exactly why.

But long-term cicada eating can overwhelm a dog’s digestion.

Cockroaches

They carry all kinds of bacteria.

Grasshoppers

Common near farms, so do not let your dog eat them.

They may carry crop pesticides.

Stink bugs

Eating one occasionally is fine, but many can burden the stomach.

By the way, do not dogs find them smelly?

Slugs

Avoid them. They carry lung-fluke larvae.

If your dog eats one, seek a vet immediately.

Spiders

Most spiders are harmless to dogs.

The only worry is the black widow, and wild ones are rare in China.

Bees

The only danger to a dog is the stinger on the bee’s tail.

So do not let dogs eat bees. Anyone who has been stung knows how painful it is.

Butterflies

They visit flower buds that may carry substances your dog is allergic to.

Luckily butterflies are hard for dogs to catch, and they taste bitter, so you need not worry.

Flies

Strictly speaking, eating one is fine; frequent eating needs caution.

Moths

Like flies, occasional is fine, but frequent eating causes stomach problems.

Earthworms

They may carry various soil bacteria.

So it is best to keep dogs away from them.
