Can dogs eat tuna?

Overview

Tuna is a popular fish consumed by humans, but it's essential to determine whether it's safe for canine consumption. Dogs have different nutritional needs than humans, and tuna's mercury content and potential allergens make it a food that requires careful consideration.

Benefits

None

Risks

• Mercury toxicity: Tuna contains high levels of mercury, a toxic substance that can accumulate in a dog's body and cause harm. Mercury poisoning can lead to symptoms like vomiting, diarrhea, and seizures.
• Allergies and sensitivities: Some dogs may be allergic or sensitive to tuna, which can cause skin issues, digestive problems, and ear infections.
• Thiamine deficiency: Tuna is low in thiamine, a vital nutrient for dogs. A thiamine deficiency can lead to symptoms like seizures, paralysis, and heart problems.

Guidelines

• Choose low-mercury tuna: Opt for skipjack or albacore tuna, which have lower mercury levels than bluefin or yellowfin tuna.
• Cook or rinse canned tuna: Canned tuna can contain high levels of salt and preservatives. Cooking or rinsing the tuna can help reduce these risks.
• Feed in moderation: If you decide to feed your dog tuna, do so in small amounts (about 1-2 tablespoons per 10 pounds of body weight) and only as an occasional treat.
• Consult with your veterinarian: Before introducing tuna into your dog's diet, consult with your veterinarian to determine the best course of action and ensure your dog is not at risk of mercury toxicity or other adverse reactions.
