Can Dogs Eat Parsley? A Complete Guide for Pet Owners
Find out how a common herb can freshen breath, boost vitamins, and avoid risky compounds.
Parsley is a popular culinary herb prized for its fresh flavor and nutritional value. But as a dog owner, you may wonder: Can dogs eat parsley? The short answer is that certain types of parsley can be a healthy treat for dogs when fed in moderation and with care. However, not all parsley varieties are created equal, and there are important safety considerations to keep in mind.
Understanding Parsley: What Is It?
Parsley (Petroselinum crispum) is a leafy green herb commonly used in cooking, garnishes, and salads. Its bright taste comes with a pack of vitamins and minerals, making it popular for both people and pets. There are two main varieties found in kitchens and gardens:
- Curly parsley: Has tightly curled, ruffled leaves; this is the variety most often considered safe for dogs in moderation.
- Flat-leaf parsley (Italian parsley): Features flat leaves; this variety is commonly used in cooking but has safety concerns for pets.
Is Parsley Safe For Dogs?
The safety of parsley for dogs depends on the type and amount consumed:
- Curly parsley: Safe in small, fresh amounts as an occasional treat or food topper for most healthy dogs.
- Flat-leaf (Italian) parsley: Toxic to dogs in significant amounts due to a compound called furanocoumarin, which can cause skin issues and other health risks.
Veterinarians and the ASPCA warn that large amounts of flat-leaf parsley can increase sensitivity to sunlight (photosensitization), resulting in a higher risk of sunburn and dermatitis. All forms of parsleyâif consumed in excessive quantitiesâcan cause digestive upset.
Parsley Varieties at a Glance
| Parsley Variety | Safe for Dogs? | Key Cautions |
|---|---|---|
| Curly Parsley | Yes, in small amounts | Feed only as occasional treat; monitor for reactions |
| Flat-leaf (Italian) Parsley | No | Contains furanocoumarin, can cause skin issues, photosensitivity |
| Spring Parsley | No | Contains compounds linked to toxicity and vision risks |
Health Benefits of Parsley for Dogs
When used correctly and in moderation, curly parsley can offer dogs several nutritional and medicinal benefits. The main advantages include:
- Freshens breath: Parsley’s natural antimicrobial properties help decrease odors and freshen your dog’s breath.
- Vitamins and minerals: Source of vitamins A, C, and K, plus folic acid, chlorophyll, and minerals like potassium, calcium, and magnesium.
- Antioxidant boost: Rich in antioxidants that combat cell-damaging free radicals, supporting immune function and cellular health.
- Supports kidney health (for healthy dogs): Acts as a mild diuretic, promoting urination and potentially helping to flush out urinary tract bacteria. (Note: Dogs with kidney disease should NOT be fed parsley.)
- Anti-inflammatory properties: Traditionally used to reduce inflammation and support joint health.
Key Nutrients in Parsley (per 5g fresh serving):
- Vitamin A: Supports vision and immune health
- Vitamin C: Immune system and collagen production
- Vitamin K: Bone and blood health
- Folic acid
- Calcium and Magnesium
- Antioxidants (chlorophyll, flavonoids)
Risks and Precautions: When Is Parsley Bad for Dogs?
What others are reading
Despite its benefits, parsley comes with several risks if the wrong type or too much is fed. Key risks include:
- Toxicity from Flat-leaf/Italian Parsley: Contains toxins that can cause increased sun sensitivity, dermatitis, and potentially more severe health issues.
- Digestive upset: Overeating parsley of any kind may cause vomiting, diarrhea, or stomach upset.
- Furanocoumarins: Especially in some non-curly varieties, these compounds are linked to toxicity, particularly if ingested in substantial amounts.
- Allergies and sensitivities: Some dogs may experience itching, swelling, or gastrointestinal reactions even to small quantities.
- Diuretic effects: Parsley can increase urination, which may be problematic for dogs with kidney disorders or on certain medications.
- Reproductive risks: Parsley acts as a uterine stimulant; pregnant or lactating dogs should not be given parsley due to the risk of complications.
Dogs That Should NOT Eat Parsley
- Pregnant or lactating dogs
- Dogs with kidney disease or a history of urinary stones
- Dogs with known parsley or plant allergies
- Dogs on diuretics or certain medications (consult your vet first)
How to Safely Feed Parsley to Your Dog
If you plan to introduce parsley to your dogâs diet, follow these vet-approved guidelines:
- Choose only curly parsley: Avoid flat-leaf or spring parsley altogether.
- Source fresh, organic parsley: This reduces pesticide exposure and maximizes nutrient content.
- Start with a small amount: 1/4 teaspoon finely chopped for small dogs, up to 1 teaspoon for large dogs, mixed with food.
- Avoid stems and seeds: Both can be tough to digest or potentially irritating.
- Skip parsley oils, extracts, or concentrated supplements: These forms are much more potent and can be dangerous.
- Monitor for adverse reactions: Watch for vomiting, diarrhea, itching, swelling, or behavioral changes.
- Consult your vet: Especially if your dog has any pre-existing health conditions or if youâre uncertain about suitability.
Tip: Parsley can also be blended into homemade dog treats or mixed with yogurt for a fresh, nutritious boost. Always adhere to moderation!
Sample Recipe: Parsley Breath-Freshening Dog Treats
- 1/2 cup chopped fresh curly parsley
- 1 cup whole wheat flour
- 1/4 cup grated carrot
- 1 egg
- Water as needed
Mix, roll out, cut into shapes, and bake at 325°F for 20â25 minutes. Cool before servingâtreats should be given sparingly.
How Much Parsley Is Safe?
The right portion depends on your dogâs size and health:
- Small dogs (under 20 lbs): Up to 1/4 teaspoon, 2â3 times per week
- Medium dogs (20â50 lbs): 1/2 teaspoon, 2â3 times per week
- Large dogs (over 50 lbs): 1 teaspoon, 2â3 times per week
Never exceed 1 tablespoon of finely chopped curly parsley per 20 pounds of body weight in a single serving. Introduce smaller servings first to check for tolerance.

Frequently Asked Questions (FAQs)
Can I give my dog parsley every day?
It is best to offer parsley as an occasional treat rather than a daily supplement. Regular small amounts can help freshen breath and provide nutrients, but frequent or large servings increase the risk of digestive upset or other health issues.
What if my dog accidentally eats flat-leaf parsley?
If your dog ingests flat-leaf (Italian) parsley, monitor closely for vomiting, diarrhea, excessive scratching, or sun sensitivity. For large amounts or severe symptoms, contact your veterinarian immediately.
How do I spot an allergic reaction to parsley?
Watch for itching, redness, swelling, vomiting, diarrhea, or difficulty breathing. Discontinue parsley and seek veterinary care if symptoms are significant.
Are parsley seeds safe for dogs?
There is no verified research confirming the safety of parsley seeds for dogs. Many sources warn that seeds may be especially toxic. Avoid parsley seeds entirely.
What other herbs are safe for dogs?
Several culinary herbs, such as basil, mint, and rosemary, are generally safe in small amounts. But always double-check each herb and consult with your veterinarian before introducing new foods to your dogâs diet.
Is dried parsley safe?
Dried curly parsley is less nutritious but can still be used sparingly for breath-freshening or flavor. Stick with moderate amounts and avoid dried Italian parsley.
Can parsley be used to treat bad breath in dogs?
Curly parsleyâs antimicrobial properties make it a popular ingredient in commercial dog treats and breath-freshening products. However, it should never replace regular dental care and veterinary check-ups.
