If you are wondering if lettuce toxic to dogs, the answer is “no.” Lettuce is not harmful to dogs when served in moderation. However, certain greens can be toxic to dogs if they overeat it. That is because greens contain various fat-soluble vitamins like A. And too much of it can lead to internal organ damage.

With that being said, the lettuce is only bad for your dog if he ingests a lot of it. Besides containing those potentially dangerous vitamins, lettuce also contains a lot of water. In fact, water makes up 95% of the lettuce content.

That means the more lettuce your dog eats, the more water he ingests. In certain instances, too much water can cause a dog to experience water toxicity. If this happens, your dog will experience symptoms such as vomiting and diarrhea (and as a result – dehydration).

So being a responsible pet guardian, you must first consult with a veterinarian before deciding whether or not your dog should eat lettuce.
