How Many Cockroaches Will It Take to Make My Dog Sick?

Usually, eating one cockroach won’t cause serious harm to your pooch. As long as the animals aren’t carrying any diseases or dangerous substances, the most these pests will do is cause some mild indigestion. Of course, if your dog feasts on several roaches, he’s more likely to have an upset stomach. 

When cockroaches harbor pathogenic bacteria or parasites, they can infect your dog. Fortunately, it takes more than one insect to harm most healthy pooches. Of course, dogs that have regular check-ups and are up-to-date on their vaccinations will be best equipped to fight off potential infections. 

In the case of secondary poisoning, one critter is also usually not enough to make your pup seriously ill. However, if you suspect your dog ate a poisoned cockroach, you should call your veterinarian.

Why Are Roaches Potentially Harmful to Dogs?

Cockroaches are one of the most common pests in America, and some dogs love to eat them. Even though these pesky critters aren’t inherently harmful, they can harbor disease-causing bacteria like Salmonella or Staphylococcus. And if you use roach bait, the annoying insect may have some poison on its body. Finally, roaches can be intermediate hosts for parasites like roundworms and stomach worms.

  • Induce vomiting
  • Administer activated charcoal
  • Provide IV fluids as supportive care
  • Give anticonvulsant medications if your dog is seizing or has tremors
  • Provide oxygen if your pooch is having difficulty breathing

  • Administer IV fluids for support
  • Treat your pooch with antibiotics based on a blood culture
