Dogs can eat crab (and bell peppers) as they are not toxic. That being said, a dog that consumes any food product that is not part of their normal diet can (and usually does) have digestive upset as a result. Diarrhea, flatulence and vomiting would be the most common side effects.
As long as she is drinking, you can try a few home care remedies to try to avoid a vet visit. First stop all food, treats and table food. I would feed her a diet of chicken and rice only (1/3 chicken, 2/3 rice- no spices no fat) to ease the stomach and help prevent/stop diarrhea. Chicken and rice is highly digestible and should not irritate the stomach. This can be fed over the next few days and slowly weaned onto a regular diet if she improves. I would also add some canned pumpkin (not spiced) 1 tablespoon per meal to bulk up the stools and calm the intestine. Pumpkin is a very safe natural remedy that will help regulate the digestive tract. It can be used for both diarrhea or soft stools and constipation.
The most important thing is to ensure that she is drinking well- it is very important that he remains hydrated. Offer room temperature water only as cold water can aggravate the stomach and induce vomiting.
If she vomits. Withhold all food and water until 2-3 hours after she stops vomiting. At that time introduce water in very small (tablespoon amounts) waiting 30 minutes in between to ensure she keeps it down. You can also offer her small amounts of Pedialyte or Smart Water electrolyte solutions- also room temperature. This will help replace the electrolytes she loses in the vomiting. After keeping water down, food can be introduced 6-12 hours after vomiting- also in small portions waiting 30 minutes to ensure there is no vomiting.
If at any time she begins violently vomiting, becomes severely lethargic, strains to defecate without production, stomach becomes tight or distended, gums become pale, or has any additional symptoms, I would have her seen today. Otherwise, she should begin to improve over the next 12 hours. If her symptoms persist or worsen, I would have her evaluated by a vet.
