Important Note About Tuna and This Food
Tuna is rich in nutrients like protein, omega-3 fatty acids, vitamin B12, selenium, and niacin. However, it also tends to contain higher levels of mercury compared to other fish. According to PetMD, tuna should only be given to dogs in moderation.
This recipe is intended as an occasional meal or special treat and not a regular part of your dog’s diet.
How to Store the Food and How Long It Will Last
Store leftovers in an airtight container in the refrigerator for up to 4 days.
For longer storage, freeze the casserole in individual portions using freezer-safe containers or plastic bags. It will last up to 3 months in the freezer. Thaw overnight in the fridge before serving.
You can warm it slightly in the microwave before serving, but make sure it’s not hot.
Is this recipe suitable for puppies?
No. Do not feed tuna to puppies. Their developing systems are more sensitive to mercury, and even small amounts could be harmful.
Can people eat this food?
Yes, everything in it is safe for human consumption. You may want to add a little seasoning to your portion, but there’s no reason you can’t give it a taste!

Nutrition
Serving Amount
The amount of food to feed your dog depends on size, breed, activity level, and overall health. A general guideline is 1 cup of food for every 20 pounds of body weight, but then goes down as the weight increases. Most dogs need 2-3% of their body weight in food daily. For personalized feeding advice, it’s always best to consult with your veterinarian.
And don’t forget, when introducing any new food, start with a small amount to make sure your dog tolerates it well.
