* Food poisoning: Rotten shrimp can contain bacteria such as E. coli and Salmonella, which can cause food poisoning in dogs. Symptoms of food poisoning can include vomiting, diarrhea, abdominal pain, fever, and lethargy.
* Nutritional deficiencies: Rotten shrimp may not provide the nutrients that your dog needs, which can lead to nutritional deficiencies. Symptoms of nutritional deficiencies can vary depending on the nutrient that is lacking, but may include weight loss, poor coat condition, skin problems, and decreased energy levels.
* Allergies: Some dogs are allergic to shrimp, and eating rotten shrimp can trigger an allergic reaction. Symptoms of an allergic reaction can include itching, swelling, difficulty breathing, and vomiting.
If you think your dog has eaten rotten shrimp, it is important to contact your veterinarian immediately. Treatment will depend on the symptoms that your dog is experiencing.
