Puppies need food that is small and easy to chew but also high in nutrients to support their early growth. 

Jack Russell Terrier puppy food needs to have a high moisture content while they are switching from their mother’s milk to solid food, much like babies, it takes their digestive system time to adjust to an adult diet.

A balanced diet of fresh dog safe food and biscuits or tinned is best.

What to avoid feeding a Jack Russell puppy

Some poorer quality or cheap food for Jack Russells can have substandard ingredients or fillers that aren’t important to a dogs diet.

These can cause issues with digestion and toilet habits, spending a little more in the short term can have much better outcomes long term and save costly vet bills. 

Lookout for these ingredients in your Jack Russells diet;

  • Generic meat – Look for specific meat like pork, beef or duck listed high on the ingredients label. Generic labelling of “meat” can mean it’s just factory leftovers, you don’t know what’s in it or where it came from.

  • E numbers – Preservatives and additives that aren’t natural aren’t any good for your dog’s health. Check the label for natural ingredients.

  • Cheap fillers – Manufacturers use cereals, corn and wheat to bulk out or hold together dog food. They are impossible for your dog to digest and, though it may seem cheaper, it’s just money down the toilet.

How much to feed a Jack Russell Terrier puppy

How much should I feed my 8 week old Jack Russell?

Adult dogs only need two meals per day, whereas Jack Russell puppies (up to 1-year-old) need more meals a day with a higher fat and protein content.

The recommended number of mealtimes for an 8 week old puppy is 4, spread evenly throughout the day.

This is because their stomachs are still very small and they can’t eat too much at once.

How much to feed a Jack Russell puppy really depends on age, weight and activity levels so best to check with a local vet if you are unsure.

Your dog food will have a personalised feeding guide, based on age and puppy weight in grams, on the back of the pack.

How much to feed 8 week old Jack Russell in grams?

It can be hard when you first get a puppy to know that you are giving them the right amount of food.

In our opinion, its better to overfeed than under feed your pup as long as its the right food; Puppies need protein not carbohydrates.

Try to avoid giving them human treats from your plate, it isn’t good for them and it will only lead to bad behaviours in the future.

They also need other vitamins and minerals which is why fruit and veg are great treats (carrots and cooked sweet potatoes are always popular super dog foods).

Avoid food that is sweet, salty or spicy as this can play havoc with your pups digestion.

And stick to unprocessed food to avoid hidden nasties like garlic and onion.

  • Check your pups parents for their expected adult weight.
  • Check the back of your dog food for puppy feeding guidelines or speak to your vet.
  • From 2 – 6 months split daily food into 3/4 meals spread evenly throughout the day, slowly increasing daily food amount as they get more active.
  • From 6 – 12 months reduce mealtimes to 2 meals per day, start decreasing meals as puppies growth slows down.

What is the best food for a Jack Russell puppy?

You can look out for puppy food that contains a good balance of vitamins and minerals like Calcium and Phosphorus for healthy bone growth and amino acids for muscle development.

Omega Fatty Acids are also important for the health of their skin, coat, eyes, and are important for early brain development.

Avoid supermarket brands that are packed with cereals and preservatives, all it means is more poop to clear up!

What human food can puppies eat?

Not all of the food that we eat is safe for dogs. Cooked meat and vegetables can be a great (and highly appreciated) addition to your JRs diet.

But raw meat can carry bacteria if not kept sterile, so if you wouldn’t eat it probably best not to feed it to your dog (unless its a specifically formulated raw diet).

Many fruits can also be a great addition to your pups diet, just make sure to avoid pips (like cherry stones that contain arsenic).

There are however some foods you should never give to your Jack Russell Terrier.
