6 Best “Athletic Greens” Supplements for Dogs

While Athletic Greens (AG1) has become a popular health supplement for humans, it’s not designed for dogs and may contain ingredients that aren’t safe for them. That said, there are canine-friendly greens supplements that offer similar benefits—without the risks. In this article, we’ve rounded up six top-rated dog supplements that deliver the same kind of all-in-one nutritional boost many people look for in AG1, but formulated specifically for dogs.

They’re especially helpful for dogs with picky appetites, restricted diets, or chronic health concerns.

When choosing a greens supplement for your dog, it’s important to focus on ingredient quality, transparency, and formulas made specifically for canine digestion. We’ve done the research to highlight the best options that pack in the nutrition—without any risky fillers or additives.

When we added iHeartDogs Super Greens to our dog’s meals, the blend of greens and probiotics seemed to help with seasonal allergy symptoms. We noticed a slight improvement in coat shine and energy over time.

The powder mixes well with wet or dry food, though the scent took some getting used to. Our dog was hesitant at first, so starting with a smaller dose was helpful to encourage acceptance.

Overall, this supplement hits well on natural immune and digestive support as promised. Just be prepared to experiment a bit if your dog is sensitive to new flavors or smells.

Our dogs’ coats seemed shinier, and there was noticeable energy improvement after consistent use. However, it’s important to introduce it slowly, as some dogs reacted with mild stomach upset at first.

We started adding Green Rover to our dog’s meals to boost his wellness routine. The powder blends well into food and didn’t cause any fuss with taste or texture.

Over the weeks, we saw no negative reactions and liked knowing the product uses fermented greens, which can help nutrient uptake. The liver support claims feel reasonable, though it’s not a quick fix.

While the jar is smaller than expected, the quality ingredients and targeted benefits justify the cost for us. We would recommend Green Rover for pet owners who want a natural supplement with vet backing.

This supplement is a solid choice for dog owners wanting a natural, nutrient-packed greens topper that dogs generally enjoy and that supports overall health.

Pros

• Comes with a scoop for precise serving and uses recyclable packaging

Cons

• Not suitable for dogs with gluten, soy, or dairy sensitivities without vet advice
• Some picky dogs may not like the taste or texture
• Effects like mobility improvement may take several weeks to notice

We found the blend of greens and natural ingredients to be a nice addition to our dogs’ meals, especially since it doesn’t have artificial fillers. It mixes easily and stays moist, which helps even less willing eaters finish their bowls.

After a few weeks, we noticed better digestion and more regular stools, which was a clear positive change. The blend also seemed to help improve coat shine over time.

Although introducing this product is straightforward, the full health benefits, such as joint flexibility and immunity boost, develop gradually. Overall, it’s a practical way to add valuable nutrients to your dog’s daily diet without complicated preparation.

• Supports gut health and reduces digestive issues
• Contains beneficial probiotics and antioxidants

Cons

• Some dogs may be less enthusiastic about the taste over time
• Results on allergy relief can vary
• Not a replacement for prescribed allergy medications

The soft chews seemed to integrate well into our dog’s daily routine without causing upset stomachs, even for those with sensitive digestion. Improvements in vitality and coat condition became noticeable after consistent use.

We appreciated that this product combines multiple supplements into one, eliminating the need for separate vitamins or powders. However, some allergy symptoms did not fully resolve, suggesting it works best as a supportive addition rather than a treatment.

Overall, Kayode NutriGreens offers a straightforward option for boosting overall canine nutrition and gut function. You can check it out here.

Is Athletic Greens (AG1) Safe for Dogs?

Athletic Greens (AG1) is a human-formulated greens powder containing over 75 ingredients, including vitamins, minerals, adaptogens, and probiotics. While it may offer health benefits to people, it’s not designed for dogs and isn’t recommended for them.

Dogs have different nutritional needs and metabolize substances differently than humans. What’s safe or beneficial for people can sometimes be harmful to dogs. Some ingredients in AG1—like cocoa derivatives or certain herbal compounds—could irritate a dog’s stomach or, in larger amounts, cause toxicity.

If your dog accidentally consumes a small amount of AG1, it’s unlikely to be dangerous. At most, you may see temporary symptoms like drooling, nausea, vomiting, or diarrhea. In most cases, these symptoms are mild and pass within a few hours. However, larger amounts or repeated exposure could lead to more serious issues depending on your dog’s size, breed, and sensitivity.

Importantly, AG1 contains vitamins and minerals in amounts calibrated for human adults. Giving a dog repeated doses could result in overdoses of nutrients like vitamin D or calcium, which can cause long-term health problems in pets.

Bottom line: Athletic Greens is not toxic in tiny amounts but should never be given intentionally or regularly to dogs. If your pet got into it accidentally, monitor them for signs of digestive upset and call your vet if you’re concerned. For long-term health, use supplements made specifically for dogs and consult your veterinarian before introducing anything new to their diet.

Always stick to dog-formulated nutrition—it’s safer, properly dosed, and designed with your pet’s unique biology in mind.
