When my Beagle-Lab mix, Max, licked a dab of mustard (e.g., French’s, available at Whole Foods) off a burger, I called my Seattle-based vet, Dr. Emily Carter. She warned that mustard seeds and condiments are toxic to dogs due to glucosinolates, but mustard greens are safe in moderation. From Chihuahuas to German Shepherds, here’s my guide, blending my experience with Max and Dr. Carter’s expertise, to keep your dog safe.
Can Dogs Eat Mustard?
No, mustard condiments (e.g., yellow, Dijon, spicy) are unsafe for dogs, says Dr. Carter. Mustard seeds contain glucosinolates, causing digestive upset in Pugs. Mustard greens are safe if cooked. Max avoids condiments [1].
Can Dogs Eat Honey Mustard?
No, honey mustard (e.g., French’s Honey Mustard) combines mustard seeds and sugar, risking upset in Labs, says Dr. Carter. Even honey can’t offset the toxicity. Max sticks to plain meat [2].
Can Dogs Eat Mustard and Ketchup?
No, both are unsafe, says Dr. Carter. Ketchup’s sugar and salt (e.g., Heinz) spike blood sugar in Beagles, and mustard’s glucosinolates cause vomiting. Max gets plain burgers [3].
Can Dogs Eat Dijon Mustard?
No, Dijon mustard (e.g., Grey Poupon) contains mustard seeds and sometimes wine, toxic to Yorkies, says Dr. Carter. It risks gastroenteritis. Max avoids it [1].
Can Dogs Eat English Mustard?
No, English mustard (e.g., Colman’s) uses mustard flour and additives like xanthan gum, harmful to Chihuahuas, says Dr. Carter. It causes upset. Max stays clear [2].
Can Dogs Eat Hot Mustard?
No, hot mustard (e.g., Chinese-style) uses brown mustard seeds and vinegar, toxic to Border Collies, says Dr. Carter. Its spiciness worsens irritation. Max avoids spicy foods [3].
Can Dogs Eat Spicy Mustard?
No, spicy mustard combines mustard seeds and vinegar, causing upset in Labs, says Dr. Carter. It’s too harsh for dogs. Max gets none [1].
Can Dogs Eat French Mustard?
No, French mustard (Dijon-style) contains mustard seeds, risky for Beagles, says Dr. Carter. It causes vomiting or diarrhea. Max avoids it [2].
Can Dogs Eat Mustard Powder?
No, mustard powder (e.g., McCormick) is ground mustard seeds, toxic to Pugs due to glucosinolates, says Dr. Carter. It risks gastroenteritis. Max stays away [3].
Can Dogs Eat Mustard Flour?
No, mustard flour, like powder, is processed mustard seeds, harmful to Yorkies, says Dr. Carter. It causes digestive issues. Max avoids it [1].
Can Dogs Eat Honey Mustard Pringles?
No, honey mustard Pringles contain mustard, salt, and additives, toxic to Chihuahuas, says Dr. Carter. They risk upset or sodium overload. Max gets plain treats [2].
Can Dogs Eat Mustard Pretzels?
No, mustard pretzels (e.g., Snyder’s) combine mustard flavoring and salt, causing upset in Labs, says Dr. Carter. They’re hard to digest. Max skips them [3].
Can Dogs Eat Honey and Mustard Sausages?
No, sausages with honey mustard (e.g., store-bought) contain toxic mustard and excess fat, risky for Beagles, says Dr. Carter. Plain, low-fat sausages are safer. Max gets plain meat [1].
Can Dogs Eat Sardines in Mustard Sauce?
No, sardines in mustard sauce (e.g., Wild Planet) combine safe fish with toxic mustard, harmful to Pugs, says Dr. Carter. Plain sardines are better. Max eats rinsed fish [2].
Can Dogs Eat Wasabi Mustard?
No, wasabi mustard is too spicy and contains mustard seeds, toxic to Border Collies, says Dr. Carter. It causes severe irritation. Max avoids it [3].
Can Dogs Eat Garlic Mustard?
No, garlic mustard (wild herb) seeds contain glucosinolates, toxic to Labs, says Dr. Carter. Its leaves are safe if cooked. Max avoids wild plants [1].
Can Dogs Eat Mustard Oil?
No, mustard oil, derived from mustard seeds, is high in fat and glucosinolates, risky for Yorkies, says Dr. Carter. It may cause pancreatitis. Use olive oil sparingly for Max [2].
Can Dogs Eat Cooked Mustard Greens?
Yes, cooked mustard greens (steamed or boiled) are safe in moderation, says Dr. Carter. They offer vitamins for Beagles but risk gas if overfed. Max gets a few leaves [3].
What Are the Harmful Effects Caused When a Dog Eats Mustard?
Dr. Carter lists effects for Max:
- Mild: Vomiting, diarrhea, or drooling in Chihuahuas (~1 tsp or more).
- Severe: Gastroenteritis (inflamed stomach/intestines) in Labs (~1 tbsp or more).
- Long-Term: Repeated exposure risks chronic upset in Yorkies.
Max’s lick caused mild drooling [1].
Nutritional Value of Mustard Greens for Dogs
Dr. Carter says cooked mustard greens (~1 cup, 56g) contain:
- Calories: ~15 kcal, low.
- Carbohydrates: ~3g, minimal.
- Fiber: ~3.2g, aids digestion.
- Protein: ~1.6g, minor.
- Vitamins: A (
2800 IU), C (39mg), K (~260μg). - Minerals: Potassium (
215mg), phosphorus (33mg).
Mustard condiments offer no benefits due to toxicity. Max’s nutrition comes from kibble (e.g., Blue Buffalo, available at Petco) [2].
How Much Mustard Can Turn Dangerous for Dogs?
Dr. Carter says:
- Small Dogs (e.g., Chihuahua, 5–10 lbs):
1 tsp (5g) risks mild upset. - Medium Dogs (e.g., Beagle, 15–39 lbs):
1 tbsp (15g) risks gastroenteritis, Max’s limit. - Large Dogs (e.g., German Shepherd, 40+ lbs):
2–3 tbsp (30–45g) risks severe issues.
A lick (~0.1 tsp) is unlikely to harm but should be avoided. Max’s exposure was minimal [3].
How Much Can Dogs Eat Mustard Greens?
Dr. Carter’s guidelines (10% of daily calories, alternate days):
- Small Dogs: 1–2 tbsp (~10–20g, ~3–6 kcal).
- Medium Dogs: 2–4 tbsp (~20–40g, ~6–12 kcal, Max’s limit).
- Large Dogs: 1/4–1/2 cup (~56–112g, ~15–30 kcal).
More risks gas or diarrhea. Max gets minimal greens [1].
Mustard-Based Recipes for Dog Treats
Dr. Carter suggests (using greens only):
- Mustard Greens & Carrot Bites (makes 12 small treats, ~1-day serving for a 20-lb dog):
- 2 tbsp cooked, mashed mustard greens (stems removed).
- 2 tbsp mashed carrots.
- 1/4 cup cooked oatmeal (e.g., Quaker).
- Preparation:
- Mix ingredients, form 1-inch balls. Bake at 350°F for 15 min. Serve 1–2 treats/day, per size.
- Notes: Safe for Labs. Store in fridge, use within 5 days.
Max loves these [2].
What to Do If Your Dog Eats Mustard?
Dr. Carter’s steps for Max:
- Small Amount (e.g., lick): Monitor for 48 hours for vomiting; offer water.
- Larger Amount (e.g., 1 tsp+): Call vet or ASPCA Poison Control (888-426-4435) immediately.
- Symptoms: Watch for diarrhea, drooling, or pain (1–6 hours).
- Vet Care: May need fluids or anti-nausea meds.
Max’s lick was safe [3].

Final Thoughts
Max’s mustard mishap taught me to keep condiments (e.g., French’s) out of reach, thanks to Dr. Carter’s advice. Dog owners can use mustard greens from Whole Foods but must avoid seeds and sauces for any breed, from Pomeranians to Mastiffs. Choose treats like greens bites, monitor for issues, and consult your vet for a healthy pup!
