Dogs are naturally curious creatures! They keep themselves occupied with sniffing, licking, and sometimes gobbling up anything that moves, including alive and dead animals, and bugs. While this behavior is usually harmless, not all insects are safe for your furry friend. Some bugs are fine to munch on occasionally, while others can cause anything from mild stomach upset to serious illness.
Remember that as a dog owner its your responsibility to keep an eye on your dog when they are inside and outside and failing to do so will result in an unnecessary and possibly costly vet visit.
Here’s a helpful guide to help you distinguish between dangerous and safe bugs for dogs to eat.
Why do dogs eat bugs?
Dogs often eat bugs out of natural curiosity and instinct. Their prey drive makes them attracted to small, fast-moving things like flies, moths, or spiders. This behavior is especially common in puppies, who explore the world with their mouths. The movement, smell, or even the taste and texture of certain bugs can be appealing or stimulating for dogs.
In many cases, bug-eating is harmless, but it can become risky if the insect is poisonous, carries parasites, or has been exposed to pesticides. While it’s a normal behavior, it’s a good idea to keep an eye on what your dog is snapping up, especially when outdoors.
Safe Bugs for Dogs to Eat
These bugs are generally considered non-toxic and won’t harm your dog if eaten occasionally:
1. Crickets
- Safe in small amounts.
- Why? High in protein and often used in pet treats and food.
- Note: Too many can cause mild digestive upset due to their exoskeletons.
2. Grasshoppers
- Safe, but feed in moderation.
- Why? Like crickets, they’re protein-rich and non-toxic.
- Caution: Wild grasshoppers might have been exposed to pesticides.
3. Flies
- Generally safe but not recommended.
- Why? Not toxic, but they may carry bacteria or parasites.
- Risk: Not dangerous unless eaten in large numbers or from unsanitary places.
4. Ants (non-fire)
- Mildly irritating, but safe.
- Why? Most ants are not toxic, but they can bite or cause slight stomach upset.
- Avoid: Red imported fire ants—they sting and can cause allergic reactions.
Dangerous Bugs for Dogs to Eat
These bugs should be avoided as they can be toxic or harmful to your dog’s health:
1. Spiders
- Dangerous, especially venomous ones like black widows or brown recluses.
- Why? Venom can cause serious symptoms like tremors, pain, or even death.
- Action: Seek vet help if your dog eats a spider and acts strangely.
2. Bees and Wasps
- Can sting the mouth or throat.
- Why? Stings can cause swelling or allergic reactions—potentially life-threatening if the throat swells shut.
- Tip: Monitor your dog if they catch a bee, and call your vet if there’s swelling or difficulty breathing.
3. Fireflies
- Highly toxic to dogs (and especially to smaller animals like lizards).
- Why? Contain lucibufagins—a chemical toxic to the heart and digestive system.
4. Ladybugs (especially Asian lady beetles)
- Can cause chemical burns in the mouth.
- Why? These bugs secrete a foul-tasting chemical that irritates the digestive tract.
5. Caterpillars
- Some are toxic, especially brightly colored or hairy species.
- Why? Some secrete venom or irritants that can cause drooling, vomiting, or worse.

6. Stink Bugs
- Not deadly but cause vomiting or drooling.
- Why? Their smelly defensive chemicals can irritate a dog’s mouth and gut.
Bugs Treated with Pesticides
Even safe bugs can become dangerous if they’ve been exposed to chemicals.
- Warning signs of pesticide poisoning: Vomiting, tremors, diarrhea, drooling, or seizures.
- Prevent exposure: Don’t let your dog eat bugs in treated yards, parks, or gardens.
What to Do If Your Dog Eats a Bug
Most of the time, a single bug isn’t a big deal. But call your vet if you notice:
- Vomiting or diarrhea
- Excessive drooling
- Lethargy or weakness
- Swelling of the face or throat
- Tremors , shaking, or difficulty walking
Final Tips for Pet Owners
Be sure to supervise your dog outdoors and avoid areas recently treated with pesticides. Keep your yard free of bug-attracting waste and don’t encourage bug-chasing as a game. If your dog feels like they’re getting praise for chasing a bug, they’re likely to do it again when you’re not watching.
Final Thoughts
It’s perfectly normal for dogs to snap at flying bugs or dig for creepy crawlies. While many insects are harmless, others can pose serious risks. Knowing the difference can help you keep your pup safe—and avoid a stressful trip to the vet.
When in doubt, it’s always best to err on the side of caution. If your dog has a habit of munching on mystery bugs, speak with your veterinarian about what’s safe in your local environment.
