Feeding Instructions

Puppy Weight Daily Feeding (cup)
5 - 15 lbs 1/2 - 3
16 - 30 lbs 3 - 6
31 - 50 lbs 6 - 8
51 - 75 lbs 8 - 10
76 - 100 lbs 10 - 13

These feeding guidelines are suggested only. Feeding amounts may vary by breed, activity level, temperament and climate.

Puppies can begin nibbling on moistened Natural BalanceĀ® Synergy Dry Dog Food before they are weaned. From 6 weeks to 6 months, feed 3 times a day. You may want to add a small amount of Natural BalanceĀ® Canned Dog Food for ease of feeding. The amount of canned dog food can be gradually decreased as the puppy matures. After 6 months, it is recommended to feed twice daily.

Adult Weight Daily Feeding (cup)
Up to 10 lbs 1/2 - 1
10 - 20 lbs 1 - 1 1/2
20 - 30 lbs 1 1/2 - 2
30 - 40 lbs 2 - 2 1/2
40 - 60 lbs 2 1/2 - 3 1/2
60 - 80 lbs 3 1/2 - 4 1/4
80 - 100 lbs 4 1/4 - 5

The amounts in the table are intended as guidelines only. The food intake should be adjusted according to the age, weight, breed, temperature, climate and activity level of your dog. Consult a veterinarian for specific weight recommendations.

Adult dogs should be fed either once or twice per day. When you first start feeding Synergy Dry Dog Food, we suggest starting with the amounts recommended in the table. Energy requirements vary with environmental conditions, temperature and activity of your dog. The amount of food should always be adjusted to suit your dog's needs.

For pregnant females: A minimal increase is needed during the first 6 weeks. Increase the amount fed up to 25% during weeks 7, 8, and 9. For lactating females: Immediately after whelping, the nutritional demand increases by 50% compared to maintenance levels. Feed in 3 equal meals per day. For working dogs: Based on the work your dog will be asked to perform, the nutritional requirements will vary accordingly. As the workload increases, the demand for protein and fat increases proportionally. Dogs in hard training will generally require twice the maintenance levels. For older dogs: As your dog begins to age, his energy expenditure will decrease. Decreasing the amount of food accordingly will allow for the maintenance of proper body weight for a less active dog.

We recommend that you do not add vitamins, minerals, or any other supplements, except upon the advice of a veterinarian. The maintenance of proper body weight is most important for your dog's health. Consult your veterinarian for specific weight recommendations for your dog.

Remember, fresh clean water should be available at all times!

Transition Instructions

When switching your dog's diet, the change should be made gradually by replacing the current food with increasing portions of Synergy Dry Dog Food. The change should be completed after 5 - 7 days.

  • Weird Smell, Darker Color

    By on

    This bag of food came later than two days. It shipped the 11th and I didn't receive it until the 16th. Upon opening the bag, it had a very different smell; a weird smell. I was and still am very hesitant to feed this to my dog. I purchase this food all the time and I have never smelt this particular scent. Because I did not receive my food in 2 days, I had to go to PetSmart and buy my dog a small bag of food. This smelt like all other bags and the color was the same as every other bag that I had. I am not sure what to do in this case. I really do not want to feed my dog this bag.

  • Perfect for our Greyhounds

    By on

    We have two greyhounds; one was on prescription dog food for her sensitive stomach which was quite expensive. We finally found this dog food over 2 years ago and it has been great. It is really hard to find in stores I have noticed. I hope Natural Balance keeps this making this!

  • Great food, HUGE kibbles

    By on

    This food was perfect for my yorkie that we recently discovered has an allergy to peas. It's a great quality food and my dogs seemed to really like the taste. My only issue is that the kibbles are huge. They are way too large for a smaller breed dog like my yorkie and shih tzu. Would definitely recommend for medium/large breed dogs!

  • Excellent for a picky eater with sensitive tummy

    By on

    My puggle loves this food. It took me years to find a food he would actually eat and that wouldn't give him foul poops. He is so excited for dinner time now! He used to always have something mixed in his food (yogurt, pumpkin, etc) now he just gobbles it up dry. Loves it and no issues with his bowel movements!

    It's the only dog food we buy. We had to experiment with other brands for digestibility when we first got our puppy. She will be 9 years old in October. We'll continue buying this dog food.

  • Super shiny coat

    By on

    I rotate foods and when Chewy stopped carrying Nutrisource, I tried this one in its place. Not only do they love it, their coats are super shiny. They've always licked their bowls clean regardless of which food, but with this one my boxer licks her bowl, the other dogs bowl, back to her bowl, and every time she walks pass her bowl she checks to see if there is anything to lick... she didnt do that with other foods.

  • New dry food

    By on Top 1000 Contributor

    Gracie has been fed ONLY Natural Balance Duck & Potato foods since she was 8 weeks old .. she will be 13 this year. Beautiful coat and no health issues I credit back to this brand. I tried Synergy since the dry Duck & Potato was on back order. Much to my surprise she licked her dish clean ... She is a very picky eater.
