Can dogs eat katydid and not hurt them?

Yes, dogs can generally eat katydids without harm, as these insects are not toxic to them. However, it's important to ensure that the katydids are free from pesticides or other chemicals that could be harmful. Additionally, dogs may have individual sensitivities, so it's best to introduce any new food, including insects, gradually and in moderation. Always consult with a veterinarian if you have concerns about your dog's diet.
