If your dog has already eaten crab
If a dog eats raw crab, crab shell, or a large/seasoned portion, monitor for vomiting, diarrhea, lethargy, or signs of GI obstruction (repeated vomiting, straining, abdominal pain, refusal to eat); shell ingestion or suspected blockage/choking warrants contacting a veterinarian promptly.

What actually goes wrong
- High sodium, cholesterol, and iodine that become unhealthy in large or frequent amounts; the shell is sharp and indigestible, risking mouth injury, choking, or intestinal blockage/injury; raw crab (e.g., found on a beach) can carry parasites; occasional allergic reactions are possible, especially in iodine-sensitive dogs. Seasoned, buttered, or salted crab, plus imitation crab and crab cakes, carry added risks beyond plain crab meat.

How much counts as too much
All treats combined should generally stay within 10% of daily calories for a healthy adult dog in ideal body condition; individual needs vary.
