Sometimes — with care
Cooked, peeled shrimp are fine for most dogs as an occasional treat — high protein, low fat. Raw shrimp and shells are the problems.
Shrimp offer protein, vitamin B12, niacin and antioxidants with very little fat, which makes them a decent training-treat upgrade. Cook them through: raw shellfish can carry bacteria like vibrio and listeria. Remove shell, head and tail — they’re choking hazards and can scratch the digestive tract, particularly in small breeds. Shrimp are also relatively high in cholesterol, so they’re an occasional treat rather than a meal-topper, and fried, garlic-butter, or breaded shrimp are off the table.
One or two shrimp for a small dog, three or four for a large dog, now and then. Introduce slowly — shellfish allergies exist in dogs, just as in people. Stop and call your vet if you see swelling, hives or vomiting after the first taste.
Plain cooked white fish (cod, hake) is a gentler seafood option; tuna only in small amounts.
