Symptoms of dog poisoning after eating seafood:

1. Skin allergies. Seafood contains high salt content, which will cause a large amount of salt accumulation in the dog's body, disrupt kidney function and excretion, and undecomposed salt will transfer to the skin surface, causing rashes.

2. Vomiting. Seafood is a pungent food and can cause discomfort and vomiting if the stomach is not properly regulated.

3. Sick. Some seafood is rich in vitamin A. If the dog cannot fully absorb these nutrients, the dog will become sick.

Care methods for dogs poisoned by eating seafood:

1. Take anthelmintics. You can feed your dog some probiotics to help regulate his stomach, or you can buy some anthelmintics for your dog to take to eliminate parasites.

2. Take anti-inflammatory drugs. To prevent the dog from scratching and rubbing the skin, causing more serious trauma, use anti-allergic drugs and anti-inflammatory drugs to treat the dog.

3. Send to a doctor for gastric lavage. Take your dog to the pet hospital immediately and ask the veterinarian to wash its stomach and get it out of danger as soon as possible.
