Can Dogs Eat Spring Mix? Vet-Approved Facts & FAQ

Spring mix is typically a mixture of different greens, such as romaine lettuce, iceberg lettuce, bibb lettuce, spinach, arugula, mustard green, and other various greens. If you have a dog that eyeballs you when you eat spring mix, you may wonder if it’s safe to let your dog eat spring mix. The answer is not straightforward, however. Why? Because it depends on what exactly is in the spring mix.

Let’s dive deeper into spring mix and determine what kinds are safe for your canine pal to share with you.


Can Dogs Eat Spring Mix?

Dogs can eat spring mix in moderation only if it contains safe ingredients. Let’s break down the safe ingredients commonly found in spring mix to see what you can feed to your dog.

Iceberg Lettuce

Lettuce can provide nutritional benefits for your dog, including vitamins A and K, and it can also provide potassium. Even so, not all lettuce is the same. Iceberg lettuce provides the least amount of nutrition, as it is 90% water. While it’s not toxic to your dog, it does little in the way of added nutrition.

Romaine Lettuce

Romaine lettuce offers a little more nutritional benefit. It’s low in calories and high in minerals, including calcium, phosphorus, potassium, and magnesium. It’s also packed with vitamins C, K, and B.


Spinach is high in vitamins A, B, C, and K. It also contains antioxidants, iron, beta-carotene, and fiber. It’s important to note that dogs should not eat a large amount of spinach due to its oxalic acid content. If ingested in large amounts, it could cause your dog to have a metabolic imbalance. This means that soluble oxalates, which contain oxalic acid, bind with calcium and magnesium in the blood. When this happens, it limits the body’s ability to absorb calcium, leading to kidney damage and even kidney failure in extreme cases.

Most healthy dogs can eat spinach in small amounts occasionally without worry. However, dogs with kidney disease are more at risk of developing serious issues from eating too much oxalic acid.


Arugula is perfectly safe for dogs in moderation. It’s packed with vitamins, minerals, and fiber. It’s also a good source of calcium and potassium. Arugula also contains oxalate acid but not as much as spinach. Still, arugula should only be given in moderation.

Mustard Greens

Mustard greens contain calcium, vitamin K, and lots of fiber to promote bone health and a healthy metabolism. However, mustard greens must be cooked before feeding to your dog. Raw mustard greens may be tricky for your dog to digest, leading to tummy upset.

Is Salad Dressing Safe for My Dog?

Salad dressing is not safe for your dog. It has too many unsafe ingredients, and some are even toxic to dogs, such as balsamic vinegar, garlic, and onion. Salad dressing is also processed with salt, oils, vinegar, and spices, to name a few, and your dog simply should not eat it. Let’s just add that salad dressing can be high in fat and calories as well, two things your dog just doesn’t need.

How to Feed Spring Mix Safely to Your Dog

If your pooch shows interest in eating spring mix, ensure you wash all leafy greens thoroughly before feeding any to your pooch due to possible pesticide contamination.

Only give small amounts in moderation, no more than once a week. You can add a little to your dog’s regular food, and be sure to chop up the greens for easier digestion. If you feed mustard greens, cook them first. Dogs receive all the necessary nutrients from their typical diet, and leafy greens should never replace your dog’s regular diet.

Tips for a Healthy Doggie Diet

Dogs require a complete and balanced diet consisting of proteins, fats, carbs, vitamins, minerals, and water. The dog food you feed should be high quality without artificial preservatives or fillers. Always feed according to the feeding guidelines on the food packaging to prevent obesity, and consult your veterinarian if you’re unsure how much or which food to feed daily.


Final Thoughts

Not all dogs care for spring mix, and that’s okay. If your dog is like mine, she’ll look at you when you place it in her bowl with a look like, “Hey, where’s the good stuff?” However, if your dog shows interest, you can safely give them a little in moderation, as long as all the ingredients in the spring mix are safe for dogs to eat, like the ones mentioned above.

If you buy spring mix in a package, check all ingredients to ensure they are safe, as some spring mix ingredients may vary depending on the manufacturer. If you make it yourself, it’s safe to use the ingredients mentioned above; just remember to cook mustard greens beforehand and avoid feeding salad dressing of any kind.
