Answer:
My dog is a vegetarian.
Step-by-step explanation:
In the original statement, the speaker says that their dog doesn't eat flesh. By converting this statement into an affirmative sentence, the speaker is providing a clear statement of what their dog does eat, which is vegetables or other non-animal-based food items. The sentence "My dog is a vegetarian" affirms that the dog's diet does not include meat or other animal products.
