Can Dogs Safely eat Crab Shells? Exploring the Facts

Crab is a tasty treat many dog owners want to share with their furry friends. However, while crab meat is excellent for dogs, the hard outer shells are another story. Crab shells are sharp, splintery, and pose a significant health hazard. So, can dog eat crab shells? The short answer is no. Read on to learn why crab shells are dangerous for dogs and how to feed your pup seafood safely.

Dogs should never eat crab shells. The rigid exoskeletons can damage a dog’s mouth, throat, and digestive tract. Swallowing crab shells whole or eating shell fragments can cause lacerations, choking, blockages, vomiting, and severe abdominal pain. Larger pieces may require surgery to remove. While tiny flakes may pass through the digestive system, it’s impossible to predict, so it’s best to play it safe. Keep all crab shells away from your dog to avoid any risks of injury, choking, or gastrointestinal obstruction. Only feed the meat, not the shell.

Crab shells have no nutritional value for dogs. They are indigestible and mainly composed of calcium carbonate and chitin. These minerals are not harmful in small amounts, but large quantities can potentially cause an upset stomach. The sharp, rigid texture is the main danger, as crab shells can lacerate internally and cause obstructions. Put, crab shells provide zero dog benefits and pose substantial physical hazards. There is no reason to feed crab shells intentionally.

Sharp crab shell edges pose many risks:

  • Cuts and puncture wounds in mouth, throat, stomach
  • Choking hazard
  • Intestinal blockages
  • Vomiting, diarrhea, loss of appetite, lethargy
  • Abdominal pain, bloody stools
  • Infection from puncture wounds
  • Possible need for emergency surgery if obstruction occurs

It is potentially fatal if left untreated. With no benefits and substantial dangers, it’s clear that crab shells have no place in a dog’s diet. Stick with crab meat for safe seafood.

If your dog accidentally eats a crab shell, watch them closely for signs of distress like choking, vomiting, or abdominal pain. Do not induce vomiting due to the risk of re-injury. Call your vet right away if you notice any concerning symptoms. Your vet may recommend an endoscope or surgery to remove lodged shell pieces. Early treatment gives the best chance of recovery.


Dog cannot eat crab shells. Crab shells are a dangerous hazard for curious canines. While shellfish meat is delicate in moderation, shells should be discarded where dogs can’t reach them. Avoid any risk of choking, obstruction, or internal damage by keeping your dog far away from crab shells. Only offer the meat for a safe treat.
