Can Dogs Eat Parsley? Risks and Benefits of Parsley for Dogs

The parsley plant (genus Petroselinum) is an herb in the Apiaceae plant family. Primarily a garnish, parsley adds an attractive pop of green color and vegetal flavor, making it the perfect final touch in the cooking process. Chefs use it alongside other common herbs, such as thyme, rosemary, peppermint, and oregano. Although parsley is endemic to the Mediterranean region, its popularity in cuisine has led to its wide distribution across the globe.

It’s generally safe to serve your dog a small amount of fresh parsley tea or essential parsley oil; however, only a specific type of parsley—curly parsley—is safe for dogs. All other varieties of parsley carry toxins that endanger canines and could lead to several health problems.

To keep your pet from developing adverse effects, limit a serving to one tablespoon per twenty pounds of body weight. As with any new food, introduce the parsley gradually and always monitor your dog for allergic or gastrointestinal reactions.

The only parsley that is safe to feed to your dog is a small amount of curly parsley, which might offer a few health benefits, including:

1. 1. Better breath: If you want to improve your dog’s breath, allow your pet to nibble on a few sprigs or add a teaspoon of parsley oil to your dog’s water bowl.
2. 2. Boosted immunity: Your furry friend might benefit from the antimicrobial and anti-inflammatory properties of parsley. Eating this herb periodically in small amounts could help your dog defend itself against life-threatening bacteria, such as salmonella and listeria. Additionally, parsley is a diuretic, making it potentially doubly effective at helping your pet flush out the bacteria that causes urinary tract infections.
3. 3. Good cellular health: Curly parsley contains vitamin A, vitamin C, vitamin K, folic acid, and chlorophyll—antioxidants that could combat free radicals in your pet’s body, deterring cellular degeneration. Parsley also contains the essential minerals calcium, potassium, and magnesium, all of which your dog’s body requires to maintain healthy brain and muscle functions.

While it’s safe to feed your dog curly parsley on occasion, other types of parsley can contain toxins that are harmful to canines. With that in mind, consider these potential health risks before adding parsley to your dog’s meals:

1. 1. Blindness: Spring parsley, flat-leaf parsley, and Italian parsley can contain high amounts of furanocoumarins—a toxin that can cause blindness and dermatitis in dogs. The American Society for the Prevention of Cruelty to Animals (ASPCA) strongly recommends against feeding your dog any parsley except the curly variety for these reasons.
2. 2. Kidney problems: Avoid feeding large amounts of parsley to dogs that have kidney problems due to the herb’s high fiber content and diuretic properties, as these two things could exacerbate a pet’s already existing health issues.
3. 3. Pregnancy complications: Parsley can cause early contractions in pregnant dogs. These premature contractions can lead to delivery complications, putting the lives of both the mother and puppies at risk.

Certain human foods and beverages can cause adverse reactions in canines, so always consult your veterinarian to determine whether it is safe to add these items to your pet’s diet. This article is for educational and informational purposes and is not a substitute for medical or dietary advice.
