My dog ate a spider killed by bug spray. He's fine, should I worry?

Updated On September 23rd, 2025

Pet's info: Dog | Boston Terrier | Male | neutered | 7 months and 7 days old

My dog might have eaten a spider that was killed by using insecticide. I am not sure if he did, maybe the spyder has mannaged to crawl away. But I am worried that he might have eaten it. It has been a day since this happened and my dog seems to be feeling fine. Should I be worried?

In general, most over the counter pesticides when dry, will not harm pets. The most common signs seen will be some transient vomiting, possible drooling, and possibly diarrhea when ingested in small amounts. Obviously there are many different kinds of pesticides available and the signs associated with them can vary greatly. The label on the original container for the pesticide should have a phone number to contact incase of concerns and more specific guidance may be found there. Ingestion of dead spiders is not likely to lead to any significant illness. As your dog is reportedly fine, it is unlikely you will see any problems at this time. Of course, if you notice your dog acting ill, please seek veterinary attention.
