Harringtons advanced science diet is a complete food for all dogs aged 8 weeks onwards. The recommended daily servings shown in the chart are a guide only. How much you feed depends on age, breed and level of activity and you should use your own judgement to determine the correct amount of food needed for your dog. For active dogs add 10% more food. Young and growing dogs require feeding little and often and to appetite. Always make sure that your dog has access to fresh water at all times. When changing dog foods, we recommend that you do so gradually. Store in a cool, dry place and fold down the top of the bag after opening.

Help & Advice


My pet is over 7 years old, is this product still suitable?

Yes - although our packaging states 1-7 years, this product is still suitable for older dogs

What is the difference between small dog food and another adult food except for the size of the kibbles?

Small dogs can benefit from extra protein in their diet, which the small breed dog food gives them.

What are the phosphorous levels of your dry foods?

We do not measure phosphorous levels in our foods. If your dog requires a low/high phosphorous
level on advice from your vet, you will need a specialist food. Your vet should be able to advise you.

When do you change a puppy from puppy food to adult food?

The point at when you change over from puppy to adult food is a personal choice. General advice is to begin to make the change once your puppy is around three-quarters expected adult size and
many people choose to do so at some point between 9 and 18 months. 

The main difference between our puppy and adult varieties is that puppy contains higher levels of protein to assist with the high growth rate associated with that life stage. Our adult varieties are suitable to feed from the age of 8 weeks, although when feeding an adult variety to a growing puppy we do advise that you feed according to your puppy's appetite. This ensures they grow at the correct rate and consume enough nutrients to support this.

Do you make a food for a diabetic dog?

We do not add sugar to our Harringtons dog food but there are natural sugars present in the
ingredients. Usually complex carbohydrates such as those found in whole grain are best as these are broken down in the digestive system slowly and so avoid peaks and troughs in the sugar levels in the body. In most of our foods we do use whole grain wheat and/or maize which take longer to digest. We therefore do not recommend grain free food for diabetic dogs.

It is often a good idea to feed your dog small portions of food more often as this will also help to keep sugar levels stable.
