Can Dogs Eat Anchovies? Small Fish, Big Benefits
Yes — dogs can eat anchovies in moderation when prepared safely; they’re nutrient-dense but can be risky if salty, oily, or spoiled.
Quick Safety Summary>
- Verdict: Yes — conditional. Plain, well-prepared anchovies can be a healthy occasional treat for most dogs; salty, canned, spiced, or rancid anchovies are not safe.
- Major benefits: high-quality protein, omega-3 fatty acids (EPA/DHA), calcium (if eaten with bones), vitamin D.
- Major risks: high sodium (especially canned/salted anchovies), bones/choking, spoiled fish (histamine), parasites/pathogens if raw, and rancid oil leading to pansteatitis.
- If your dog shows vomiting, diarrhea, excessive thirst, tremors, seizures, or collapse after eating anchovies or salty fish — contact your veterinarian or ASPCA Animal Poison Control immediately: (888) 426-4435.
Quick Verdict (first thing)
Yes — dogs can eat anchovies in moderation and when they are prepared safely (plain, low-salt, cooked or preserved in a pet-safe way). Anchovies are nutrient-dense small fish that can be a healthy occasional addition to a dog’s diet, but there are important caveats about sodium, bones, spoilage, and preparation.Why anchovies can be good for dogs
Anchovies are oily, small fish that are rich in nutrients useful for dogs:- High-quality animal protein that supports muscles and tissue repair.
- Omega-3 fatty acids (EPA and DHA) that reduce inflammation and support skin, coat, joint, and heart health.
- Vitamins and minerals including vitamin D, calcium (especially if small bones are consumed), phosphorus, and selenium.
- Calories: ~130 kcal
- Protein: ~20 g
- Total fat: ~4–6 g
- EPA + DHA (combined omega-3s): ~800–1,200 mg (varies)
- Calcium: 100–250 mg (higher if small bones eaten)
- Sodium: naturally low (~100 mg) but skyrockets if salted/canned
Risks and toxicology details
Understanding the hazards helps you decide how to offer anchovies safely.1. High sodium (salt) — the biggest practical risk
Canned or salted anchovies often contain very high sodium — sometimes thousands of milligrams per 100 g. Dogs are far more sensitive to salt overload than humans. Salt toxicity can cause vomiting, diarrhea, excessive thirst, tremors, disorientation, seizures, and even death in severe cases. Puppies, small breeds, and dogs with heart or kidney disease are at higher risk.If your dog eats salted or canned anchovies and shows signs of salt toxicity, contact your veterinarian or the ASPCA Animal Poison Control immediately. (ASPCA Animal Poison Control: https://www.aspca.org/pet-care/animal-poison-control)
2. Bones and choking/obstruction
Anchovies are small and have many tiny bones. Cooked fish bones can splinter and cause throat injury, esophageal or intestinal perforation, choking, or obstruction. For safety:- Offer anchovies boneless (remove bones) or well-chopped; canned anchovies packed in oil often have soft bones but canned varieties are usually high in salt.
- Monitor for coughing, gagging, retching, vomiting, abdominal pain, or blood in stool after eating bones.
3. Spoilage, histamine (scombroid) poisoning, and pathogens
Improperly stored or spoiled fish can cause histamine-mediated food poisoning (scombroid), which in dogs can present as vomiting, diarrhea, and allergic-type signs. Raw fish also carries a risk of bacterial pathogens (Salmonella, Listeria) and parasites. The American Veterinary Medical Association (AVMA) points out risks of raw diets and raw seafood; cooking reduces infectious risk (https://www.avma.org).4. Rancid oil and pansteatitis (yellow fat disease)
Feeding large amounts of oily fish, especially if oils are oxidized/rancid (e.g., spoiled canned fish, old fish oil), can contribute to pansteatitis — an inflammatory condition of body fat seen most commonly in cats but reported in dogs. Signs include painful, hardened fat, lethargy, and anorexia.5. Heavy metals (mercury)
Anchovies are small, short-lived fish and generally have low mercury compared with larger predatory fish (tuna, swordfish). Occasional feeding of anchovies is not likely to produce mercury toxicity. For heavy, frequent feeding of fish to dogs, consult your veterinarian.Preparation and feeding recommendations
Follow these simple rules to make anchovies a safe treat:- Prefer fresh, plain, cooked anchovies or rinsed, low-salt canned anchovies packed in water (not oil or heavy sauce).
- Avoid salted, spiced, marinated, smoked, or anchovy paste with added salt, garlic, or onion — garlic and onion are toxic to dogs (AVMA/ASPCA note).
- Remove large bones or finely chop small fish so bones are unlikely to cause harm.
- Serve plain, without oil, lemon, or seasonings.
- Start with very small amounts to test tolerance and watch for gastrointestinal upset.
Cooking methods
Pan-sear, bake, or poach anchovies briefly until cooked through. Baking or broiling on a sheet with parchment is easy. Avoid frying in large amounts of oil or using spices.Serving sizes by dog weight (guidelines)
These are occasional treat portion suggestions for plain, cooked, or properly rinsed low-sodium anchovies (not canned in heavy salt/oil). Use these as treats only — do not replace balanced diet.- Toy/small dogs (<10 lb / <4.5 kg): 1 small anchovy (or 5–10 g) once or twice a week
- Small/medium dogs (10–25 lb / 4.5–11 kg): 2–3 anchovies (10–20 g) once or twice a week
- Medium/large dogs (25–50 lb / 11–23 kg): 3–5 anchovies (20–40 g) once or twice a week
- Large/giant dogs (>50 lb / >23 kg): 5–8 anchovies (40–80 g) once or twice a week
What about canned anchovies or anchovy paste?
Canned anchovies and anchovy paste are common in human kitchens but are frequently high in salt and sometimes preserved in oil or spices. These are not ideal for dogs. If you use canned anchovies:- Rinse them thoroughly under running water to remove surface salt.
- Choose versions packed in water with low added salt if available.
- Use very small amounts and infrequently.
When to call the vet or poison control — emergency steps
If your dog consumes a large quantity of salted/canned anchovies, anchovy paste with onion/garlic, or shows any troubling signs after eating anchovies, act quickly:Be prepared to give details: type of anchovies (fresh vs. canned/salted), amount consumed, your dog’s weight, and time since ingestion.
Practical feeding ideas and recipes
- Small training treats: lightly cooked and chopped anchovy pieces mixed with a small amount of plain cooked rice or pumpkin.
- Topping: a single finely chopped, rinsed anchovy over kibble occasionally for flavor and omega-3 boost.
- Homemade fish treats: bake mashed anchovy mixed with whole oats and egg (no added salt), cool, and break into small pieces.

- Use small, weight-adjusted servings and consult your veterinarian if you plan to use fish regularly or for therapeutic omega-3 dosing.
Frequently Asked Questions
Can dogs eat canned anchovies?
Canned anchovies are often high in salt and sometimes packed in oil or contain added seasonings (including garlic or onion). If you use canned anchovies, rinse them thoroughly, choose low-sodium/water-packed varieties, offer very small amounts infrequently, and avoid any seasoned varieties. In general, fresh, plain, cooked anchovies are safer.
Are anchovy bones dangerous to dogs?
Small anchovy bones can pose a choking hazard or may splinter and injure the throat or digestive tract. Remove bones where possible, finely chop small fish, or use boneless preparations. Monitor your dog after feeding and seek veterinary care if you see coughing, gagging, vomiting, abdominal pain, or blood in stool.
Can I feed my dog raw anchovies?
Raw anchovies carry risks of bacterial pathogens and parasites. While some owners feed raw fish, the safest option for most dogs is cooked, plain anchovies. If you feed raw fish, discuss the risks and appropriate handling with your veterinarian.
How often can I give my dog anchovies?
Treats should be occasional. For most dogs, 1–2 times per week in small amounts (see serving guidelines by weight) is reasonable. If you plan frequent feeding for therapeutic reasons, consult your veterinarian for controlled dosing and monitoring.
