Can dogs eat shellfish? Squid, clams and calamari too

The American Kennel Club says dogs can eat shrimp in moderation, as long as it is cooked and the shell is removed, and it warns that raw, uncooked shellfish carry harmful pathogens (AKC, Can Dogs Eat Shrimp?, updated February 2025, opened 2026-10-16). Squid, clams and calamari are less well covered by the big groups, so the sensible rule is the same one: plain, small, supervised, and a call to your veterinarian if your dog is on a special feeding plan. This page covers shellfish only. Fish with fins is a different subject.

What counts as shellfish

Shellfish is a kitchen word, not a tidy biology one. It covers two groups. Crustaceans, such as shrimp, wear a hard outer shell. Mollusks include clams and mussels with their two-part shells, and also soft-bodied squid and octopus. Scallops are mollusks too. When a bag says "contains shrimp" or "contains clam," that tells you which group your dog is meeting.

Plain, cooked and raw

For the people-food version, the AKC's advice on shrimp is a useful template for any shellfish: cook it thoroughly, take the shell off completely (it calls shells a choking hazard), and skip fried or breaded versions, which add fats and oils a dog does not need (same AKC article). The ASPCA separately warns that raw meat and raw eggs can carry bacteria such as Salmonella and E. coli, and lists onion, garlic and chives, plus very salty foods, among things to keep away from pets (ASPCA, People Foods to Avoid, opened 2026-10-16). That is why a plate of seafood from the table, cooked with garlic, butter or a lot of salt, is not a good thing to hand over.

Squid, calamari and clams

Honest note: when we looked, we did not find an AKC, VCA or ASPCA page written about squid, calamari or clams. So the following is our reading of the shellfish rules above, not a quote from any of them.

• Squid: plain and cooked is the only form we would consider. Cut it small and stay close while your dog eats.
• Calamari: the restaurant version is usually battered and fried, so it runs into the AKC advice against fried and breaded shrimp, which we apply to other shellfish. It often comes with seasoning and sauce too.
• Clams: shells off, plain, cooked. Clams in a sauce, a chowder or a clam bake are people food, not dog food.

The one-at-a-time rule

VCA tells owners to bring in new things slowly and one at a time, and to start with a small piece of any new treat (VCA, Dog Treats, opened 2026-10-16). If a dog has stomach trouble after shrimp, the AKC's advice is to stop, and it suggests talking with your veterinarian before any shellfish becomes a regular part of the diet. Treats also have a share to respect: VCA puts them at about 10 percent of daily calories.

Shellfish can also be a source of trouble for an individual dog, as any food can. If a veterinarian has your dog on a feeding plan, check with them before you add a new protein. We cannot tell you whether a given seafood suits your dog.

Captain's Catch, our five-ingredient medley

Every other bag we sell here holds one protein. Captain's Catch holds five, listed on the label as squid, octopus, shrimp, clam and mussel, and nothing else. No fish, no grains, no fillers, no dyes. The bag is 1.5 oz and comes out of our small-batch freeze dryers in Malvern, Pennsylvania. Captain's Catch includes imported seafood.

With five animals in one bag, expect big and small pieces, chewy and crisp ones, and no uniform shape. Break them up for a small dog, use the little ones as rewards, or crumble some over a meal. It is a treat or topper, not a complete diet, and the same bag is sold for dogs and cats.

If any one of the five has given your dog trouble before, choose a single-ingredient bag instead, where you know exactly what is in it.

• Shrimp, one ingredient
• Scallops, one ingredient
• Blue-lipped mussels, one ingredient
• Baby octopus, one ingredient

On the label: crude protein 67% minimum, crude fat 4% minimum, crude fiber 18% maximum, moisture 16% maximum, and about 64.4 kcal per ounce. Seal it between uses, keep it out of heat and damp, and set out fresh water. Treats are for intermittent or supplemental feeding, not a complete diet.
