Tuna is a common protein-rich fish fed to both humans and animals. Many pet owners wonder if it is safe and nutritious to feed tuna to nursing or lactating dogs. While tuna can provide important nutrients, there are some potential risks and precautions to keep in mind.
This article covers the key aspects of feeding tuna to nursing dogs. Topics include the nutritional needs of lactating dogs, benefits and risks of tuna, recommended tuna servings, tips for preparation, signs of allergic reaction, and consulting a veterinarian.
The goal is to give an overview of the content that will be covered in a comprehensive, objective manner. Let me know if you would like me to modify or expand the introduction section.
Nutritional Needs of Lactating Dogs
When dogs are nursing puppies, their calorie needs dramatically increase. According to the Purina Institute, the energy requirement for a lactating dog is typically two to three times higher than normal maintenance levels (source). This is because milk production requires large amounts of energy and nutrients.
In addition to calories, lactating dogs need increased protein, fat, vitamins, and minerals. According to one study, lactating dogs should consume a diet with at least 29% protein and 17% fat to meet nutritional demands (source). High quality sources of protein and fat like chicken, beef, eggs, and fish can help meet these needs.
Vitamins and minerals like calcium, phosphorus, magnesium, and B vitamins are also crucial for milk production and the health of nursing dogs and puppies. Therefore, lactating dogs benefit from specially formulated lactation diets or puppy foods which provide complete, balanced nutrition.
Benefits of Tuna for Nursing Dogs
Tuna can provide some beneficial nutrients for lactating dogs. According to the AKC, tuna is high in protein and omega-3 fatty acids, both of which are important for nursing dogs [1]. Nursing dogs need extra protein to support milk production and puppy growth. Omega-3s also help support the immune system and provide DHA for brain development in puppies.
The high protein content in tuna makes it a good occasional addition to a nursing dog’s diet. Just 3 ounces of canned tuna provides about 20 grams of protein. Combining tuna with the dog’s regular food can help boost overall protein intake. Additionally, the omega-3s from tuna support the nursing dog’s coat and skin health while providing nourishing fats for her puppies.
Potential Concerns with Feeding Tuna
While tuna can be a nutritious occasional snack for nursing dogs, there are some potential concerns to be aware of.
One of the biggest risks associated with feeding tuna is the mercury content. As referenced in this AKC article, tuna contains higher levels of mercury than many other types of fish. Consuming too much mercury can result in mercury poisoning, which can lead to severe health complications in dogs, including kidney failure and even death. Pregnant and nursing dogs are especially susceptible to mercury toxicity.
Another potential concern is the sodium content in canned tuna packed in oil or water. As noted in this Purina article, the sodium content can be quite high, which is not ideal for nursing dogs who need to watch their salt intake. Excess sodium can put strain on dogs’ kidneys and lead to dehydration.
To mitigate these risks, it’s recommended to only feed tuna to nursing dogs in strict moderation and opt for low-sodium varieties when possible. Consulting your veterinarian can help determine safe tuna serving sizes for your individual dog.
Recommended Tuna Servings
When feeding tuna to nursing dogs, it’s important to stick to recommended serving sizes and frequency.
The general guideline is to limit tuna to no more than 2 servings per week. A single serving for a medium-sized dog is around 1-2 ounces of canned tuna. For smaller dogs, give just 1 ounce or less. Larger breeds may be able to handle up to 3 ounces. But more than 3 ounces at a time is not recommended.
Aim to incorporate tuna as part of your dog’s regular, balanced diet. Tuna should be an occasional treat, not a staple protein source. Feeding more than 2 servings a week significantly increases potential risks.
Tips for Preparing Tuna
When preparing tuna for your nursing dog, there are some important considerations to keep in mind.
Canned tuna generally contains more sodium than fresh tuna, so it’s best to opt for fresh when possible. Look for tuna steaks or fillets and aim to cook them plain without any seasoning. Steaming, baking, or grilling are all healthy preparation methods. If using canned tuna, choose options packed in water rather than oil and make sure to drain and rinse it before serving (source).
Be sure to remove any small bones as well as skin, which could present a choking hazard. Flaking the tuna into small pieces will make it easier for your dog to chew and digest. You’ll also want to limit or avoid adding oils when cooking fresh tuna, as the high fat content can lead to pancreatitis.
Refrigerate any leftover tuna to avoid spoilage and don’t leave it out for more than 2 hours. Proper storage and handling is important when feeding any raw fish to dogs.
Other Nutritious Options
While tuna can be a healthy choice for nursing dogs, there are many other nutritious options to consider as part of a balanced diet. Some great alternatives to tuna include:
Lean Meats: Chicken, turkey, and lean beef are excellent sources of high-quality protein and nutrients for lactating dogs. Look for minimally processed, unseasoned options. Lean meats also provide iron, zinc and B vitamins.1
Eggs: Whole eggs are an affordable and nutritious choice. The high protein and healthy fat help support milk production. Eggs also provide vitamin A, iron and choline.2
Dairy: Small amounts of plain yogurt or cottage cheese offer probiotics, calcium, protein and vitamins. Just introducing dairy slowly to avoid gastrointestinal upset.
Oatmeal: Whole grain oats provide B vitamins, iron and fiber. Look for minimally processed options and cook before feeding.
Fruits & Veggies: Fresh or frozen options like carrots, broccoli, apples and blueberries provide antioxidants, vitamins and minerals. Only feed in moderation.
Overall, focus on quality nutrition from natural, minimally processed sources. And be sure to also feed a premium puppy food formulated for nursing mothers to provide complete and balanced daily nutrition.
Signs of an Allergic Reaction
Some dogs can develop an allergy or sensitivity to tuna. According to WagWalking, symptoms to watch out for include itchy skin, skin infection, ear infection, obsessive chewing/licking of feet, loss of fur, and vomiting. The Dodo also notes that signs of an allergic reaction can include swelling, hives, diarrhea, and reddened skin. If your dog experiences any of these symptoms after eating tuna, stop feeding it and contact your vet. Mild allergic reactions may be treated with antihistamines, but more severe reactions could require steroids or other medications prescribed by your vet.
Consulting Your Vet
It’s important to consult your veterinarian before feeding tuna to a nursing dog. Vets can provide guidance on proper nutrition for lactating dogs and approve if tuna can be part of a balanced diet. They will consider the dog’s health history, age, breed size, and other factors.
Veterinary monitoring is advised when introducing any new food to a nursing dog’s diet. Signs of an allergic reaction or digestive issues should be reported to the vet immediately. Some dogs have sensitivities to fish and may experience vomiting, diarrhea, or skin irritation.
Your vet can suggest how much tuna to feed, if any, while nursing. They may recommend limiting tuna to small servings 1-2 times per week due to potential mercury exposure. More frequent tuna meals could lead to mercury building up in the mother dog and puppies. Veterinary guidance helps balance the benefits of tuna with the potential risks.
Schedule a vet visit if you have any concerns about your nursing dog’s diet. Your vet can analyze the dog’s nutritional needs and create a personalized meal plan. With vet supervision, tuna can potentially be included as an occasional supplement to support the increased protein and calcium needs of a lactating dog.

Conclusion
In summary, tuna can be a healthy supplement for nursing dogs when fed in moderation. The high protein and omega-3 content can help meet the increased nutritional demands during lactation. However, tuna lacks some nutrients like calcium that are vital for milk production. Additionally, issues like mercury exposure and allergies need to be considered.
The recommended serving for tuna is around 3 to 4 ounces per day. Focus on light tuna and skip albacore and large, predatory fish that accumulate more mercury. Choose tuna canned in water and drain the liquid to reduce sodium. Pair tuna with foods like yogurt, eggs, and dark leafy greens to round out the diet. Monitor your dog for signs of food allergy.
Consult your veterinarian if you have concerns about your dog’s nutrition during nursing. They can provide tailored advice based on your dog’s health history and needs. With some precautions, tuna can be a beneficial addition during lactation. But other nutrient-dense foods may be preferable if tuna raises any issues for your dog.
