Is tuna good for 6 week old puppy?

Tuna can be given to a 6-week-old puppy in small amounts, but it should not be a regular part of their diet. It's important to ensure the tuna is packed in water and free from added salt or spices. Always consult with your veterinarian before introducing new foods, as puppies have specific nutritional needs, and too much tuna can lead to Mercury exposure or other health issues. A balanced puppy food is the best option for their growth and development.
