Risks and Precautions
Shellfish Allergies
Some dogs are allergic to shellfish. Reactions range from mild (itching, hives) to severe (facial swelling, difficulty breathing). Introduce crab with only a tiny piece first and watch for 24-48 hours.
High Sodium Content
Crab contains over 900mg of sodium per 3-ounce serving even without added salt. Dogs with heart disease, kidney disease, or high blood pressure should avoid crab entirely. For healthy dogs, this is the main reason to limit portions.
Raw Crab Dangers
Raw crab can harbor harmful bacteria and parasites, including lung flukes. Always cook crab thoroughly -- the meat should be completely opaque and white.
Crab vs Other Seafood for Dogs
| Factor | Crab | Shrimp | Lobster |
|---|---|---|---|
| Protein (3oz) | 20g | 20.4g | 16g |
| Omega-3 | High (351mg) | Low-Moderate | Moderate |
| Sodium | Very High (911mg) | Moderate (292mg) | High (413mg) |
| Zinc | Very High (6.5mg) | Moderate (1.3mg) | Low (0.7mg) |
All three shellfish are safe when properly prepared. Shrimp has the lowest sodium, lobster falls in between, and crab offers the best zinc. For more omega-3 benefits, consider salmon.
