There are several bugs that are harmful to dogs due to bite or sting. You can probably guess most of them--they're detrimental to human health, as well.
Aside from bees, snakes and black widow spiders, dogs shouldn't consume caterpillars or centipedes. These bugs can be even more dangerous to dogs suffering from a more severe health condition.
Dogs are usually more likely to get into other harmful things like household chemicals and cleaners, chocolate and pesticides.
If your dog has ingested a bug or other substance and exhibits signs of illness, observe your dog and call the vet. Check your household chemicals to see what the dog might have consumed if it wasn't organic.
