We all know that ensuring a Jack Russell Terrier diet is just right is the key to having a healthy dog, but just what are the factors to consider when working out the correct diet?

Basic Information on a JRT Diet

When deciding on the best JRT diet, some basic principles should be stuck to. It goes without saying that a Jack Russell should always have access to a clean water supply, and it is also incredibly obvious that food should be made available to the dog on a regular basis – although it is equally important not to overfeed as well. Every owner of a Jack Russell Terrier should already be aware of the previous two facts, but many are not aware of the different specific requirements when it comes to vitamins, portion sizes and other nutrition, so what exactly are they?


Although the correct provision of vitamins is important to a Jack Russell of any age, puppies are particularly in need of these in correct quantities. There are a number of different vitamins that every JRT diet should include and they can often be found in specific sources. For example, Niacinamide and Biotin are two good supplements to feed, as are Folic Acid and Beta Carotene. The specific amount of vitamins that each dog will need varies, so the best advice can be gained from a vet or other professional in the field.

On a cautionary note, it is important that a JRT diet should not include any Vitamin C supplements, such as ascorbic acid and calcium ascorbate. This is because excessive Vitamin C can cause serious damage to a Jack Russell’s liver and kidneys.


Just like vitamins, the correct mineral supplements are also incredibly important in a Jack Russell Terrier diet. These supplements can be bought from nearly every good pet store and will increase the health of your Jack Russell no end! Some of the most effective mineral supplements to include in a Jack Russell Terrier diet include sea kelp (a good source of iodine), Gluconate (copper) and Zinc-GLuconate (zinc). There are also a number of other supplements that can be used; a vet will be able to advise on all of these.

As with vitamins, there is one warning regarding what minerals to feed your Jack Russell. There are a number of different sources for every mineral, yet the source could well be harmful to some breeds of dogs, while suitable for others. This is why it is incredibly important to ascertain whether a specific supplement is correct for the specific breed – if this is not done then the results could be disastrous.

Portion Size

Giving a specific figure regarding the portion size that a Jack Russell Terrier diet should have is impossible, as every single dog has a different weight and a different physiological make up. Only a professional who has examined your dog can tell exactly the correct quantity. Remember though that many dog foods already contain vitamins and minerals in them, so don’t supplement a Jack Russell Terrier diet should the quota already be fulfilled by their regular food.
