What Jack Russell Terriers need most from their food

The Jack Russell’s relentless energy and working drive shape their nutritional needs:

Energy & Stamina

One of the highest-energy breeds. Bioavailable, high-quality protein fuels sustained activity better than starch-heavy kibble.

Lean Muscle

Athletic, muscular terriers need quality protein to maintain lean muscle mass.

Dental Health

Prone to dental issues. A clean, low-starch diet reduces plaque-promoting sugars.

Digestive Efficiency

Active dogs benefit from highly digestible food — more absorbed, less wasted.

Why freeze-dried raw is right for Jack Russell TerriersJack Russell Terriers

Jack Russell Terriers are among the highest-energy breeds — tireless, athletic working dogs bred to hunt. That drive requires real fuel. Freeze-dried raw delivers high-quality, highly digestible protein in its most usable form, supporting sustained energy and lean muscle far better than the starch-heavy kibble most dogs are fed.

The high digestibility means more of the nutrition is absorbed and used — efficient fuel for an active body. The clean, low-starch profile also supports the dental health terriers are prone to. Loyal Saints provides whole-food nutrition with no fillers and no synthetic premix.

The standard is King.

Loyal Saints was built because of one dog. King’s digestive sensitivities pushed Kristina Voltin to question the ingredients, processing and nutrition behind every bowl. She formulated a whole-food, freeze-dried raw diet from human-grade quality ingredients — food she felt confident feeding King every day. Every formula is held to that standard: would I feed this to King?

For Jack Russell Terriers owners navigating the same questions Kristina faced — about ingredients, about what’s really in the bag, about whether the food is actually good — Loyal Saints is the answer she built for them.

Frequently Asked Questions

What is the best food for a high-energy Jack Russell?

High-quality, highly digestible protein is the priority. Beef is the top pick — rich, high-protein, with organ meats that fuel sustained energy and lean muscle. Freeze-dried raw delivers protein in its most usable form, supporting activity better than starch-heavy kibble.

How much should I feed my Jack Russell Terrier?

Jack Russells typically weigh 13–17 lbs and, given their high activity, need about 1⅓–1½ cups of freeze-dried raw a day as a complete meal (Beef or Turkey + Salmon; 1½–1⅔ cups of Chicken), split into two meals. Very active working dogs may need more — monitor body condition and adjust to maintain a lean, muscular frame.

Does freeze-dried raw give dogs more energy?

Many owners report increased, more stable energy after switching from kibble — the result of higher protein bioavailability and the absence of starch-driven blood-sugar spikes. For a high-drive breed like the Jack Russell, that means better-sustained energy for activity.

Is freeze-dried raw worth it for an active dog?

Yes. Active dogs do well on highly digestible nutrition — and freeze-dried raw measured 94% protein digestibility in a 2024 controlled study. The high-quality protein supports lean muscle, and the clean profile avoids the starch fillers that provide empty calories.
