Which Hydrolysed Dog Food Recipe Is Right for Your Dog? A Guide to the Ultimate Plus Range


If you have decided that hydrolysed dog food is the right direction for your dog — or you are seriously considering it — the next question is usually: which one?

The Ultimate Plus range has five hydrolysed recipes, and they are not interchangeable. Each one uses the same Freshtrusion HDP manufacturing process and the same grain-free, no-prescription foundation, but the functional ingredients, peptide profiles, and health targets are different. Choosing the right recipe for your dog's specific needs makes a real difference to how quickly you see results.

This guide will help you find the right match. Start with the quick symptom table below if you want a straight answer, or read through the individual recipe sections for the full picture.

All five recipes are available without a vet prescription, from £20 for a 1.5 kg bag and £80 for a 10 kg bag (Healthy Living from £25.99 / £85.99). All are complete and balanced for everyday long-term feeding.

Quick Answer: Match Your Dog's Symptoms to the Right Recipe

If you know what your dog's main issue is, this table will point you straight to the most appropriate recipe. More detail on each recipe follows below.

Your dog's main issue Start with
Loose stools, gas, or bloating Digestive Care
IBD, chronic gastroenteritis, or poor nutrient absorption Digestive Care
Recovering from antibiotics, illness, or dietary upset Digestive Care
Chronically smelly stools Digestive Care
Itchy skin, hot spots, or recurring ear infections Skin & Coat
Dull, dry, or flaky coat Skin & Coat
Skin reactions — face, paws, or groin itching after eating Skin & Coat
Overweight with reduced mobility Weight Control & Joint
Arthritis, hip dysplasia, or joint stiffness Weight Control & Joint
No specific condition — owner wants a cleaner everyday food Healthy Living
History of sensitivity but currently symptom-free Healthy Living
Plaque, red gums, bad breath, or dental disease Dental Care

If your dog has more than one issue — for example, digestive problems alongside skin reactions — start with the recipe that targets their most disruptive symptom first. Many owners start with Digestive Care and find that skin symptoms improve as a secondary benefit once the gut is functioning better.


What Every Recipe in the Range Has in Common

  • Freshtrusion HDP process — freshly prepared meat or fish is hydrolysed using natural plant enzymes before the kibble is made. The finished kibble contains genuinely pre-hydrolysed protein throughout.
  • Grain free — no wheat, corn, soya, or dairy. All five recipes use sweet potato and potato as the carbohydrate base.
  • No prescription required — available to buy directly. All recipes meet FEDIAF nutritional standards for everyday complete feeding.
  • Independently tested peptide profiles — every recipe has been independently analysed for peptide molecular weight distribution.
  • Made in the UK — produced at G.A. Pet Food Partners' BRC Grade A accredited facility in Chorley, Lancashire.

Side-by-Side Comparison — All Five Recipes

The sub-0.5 kDa figure shows the percentage of protein in the finished kibble that is in the most digestible, most easily absorbed form — dipeptides and tripeptides. A higher figure means a higher degree of hydrolysis, calibrated to each recipe's specific health goal.

Recipe Primary goal Sub-0.5 kDa peptides No prescription Price from
Digestive Care Gut & digestion 52% £20 / £80
Skin & Coat Skin & immunity 64% £20 / £80
Weight & Joint Weight & mobility 60% £20 / £80
Healthy Living Everyday health 64% £25.99 / £85.99
Dental Care Teeth & gums 69% £20 / £80

All recipes are grain free and available without prescription. Sub-0.5 kDa figures represent minimum confirmed percentages from independent laboratory analysis of finished kibble.


The Five Recipes in Detail

Each section below covers who the recipe is designed for, what it is not suited for, and the functional ingredients that make it different from the others in the range.

1. Digestive Care

For dogs whose gut is the starting point for everything

52%
of peptides below 0.5 kDa — most digestible fraction
From £20
1.5 kg · From £80 for 10 kg
Best for
  • Loose or inconsistent stools that don't resolve on a standard sensitive food
  • Excessive gas, bloating, or gut sounds after eating
  • IBD, chronic gastroenteritis, or poor nutrient absorption
  • Dogs recovering from antibiotics, illness, or a dietary upset
  • Chronically smelly stools
  • Food intolerances or allergies with a digestive component
Less suited for
  • Dogs whose primary issue is skin — Skin & Coat is a better starting point
  • Dogs needing joint support as the main goal — Weight Control & Joint targets this more directly
Key functional ingredients
  • Hydrolysed turkey (26% freshly prepared + 11.5% dried) — pre-digested protein at 52% sub-0.5 kDa for maximum gut absorption with minimal digestive workload
  • TruPet™ postbiotic — studied in dogs, shown to increase beneficial gut bacteria, reduce faecal odour compounds, and support a calmer gut immune response
  • Collagen peptides (1.9%) — help protect the gut wall lining, which can break down in dogs with chronic digestive inflammation
  • Lignocellulose (2.5%) — natural plant fibre with high water-holding capacity, firms loose stools without causing constipation

What If My Dog Has More Than One Issue?

This is common — dogs with food sensitivities rarely have just one symptom. Here is how to approach the most frequent combinations:

Digestive problems + skin reactions

Start with Digestive Care. The gut is the root of most immune-mediated food reactions — improving gut barrier function often reduces skin symptoms as a secondary benefit. Give it eight weeks before assessing whether Skin & Coat would be a better fit.

Skin reactions + joint stiffness

If skin is the primary concern, start with Skin & Coat — the high hydrolysis profile benefits both skin and joint inflammation. If joint mobility is the priority, start with Weight Control & Joint, particularly if your dog is carrying extra weight.

General sensitivity + weight management

Start with Weight Control & Joint. The hydrolysed protein base reduces systemic inflammation — both an allergy management strategy and a metabolic support strategy — while L-carnitine and marine collagen peptides address weight and joint function.

Everything seems fine — you just want better

Healthy Living. Designed for dogs who are not unwell but whose owners want a food that genuinely earns its place in the bowl.


How Quickly Will You See Results?

  • Digestive Care Firmer stools and reduced gas typically within 2–3 weeks. Full gut health assessment needs 6–8 weeks.
  • Skin & Coat Coat shine often improves within 3–4 weeks. Itching, redness, and ear infections typically take 6–8 weeks. This is normal.
  • Weight & Joint Joint comfort improvements — increased willingness to walk, reduced stiffness — typically within 6–8 weeks.
  • Healthy Living Gradual maintenance improvements. Better stool consistency and coat condition within 3–4 weeks.
  • Dental Care Breath improvement often noticed within a few weeks. Gum health changes take 6–8 weeks.

For any recipe used as a food trial, feed exclusively for a minimum of eight weeks — no other protein sources, flavoured treats, or chews. Mixing with other foods during a trial prevents accurate assessment.


How to Transition to Any Ultimate Plus Recipe

Introduce gradually over two weeks to give your dog's gut time to adjust:

Days 1–4
25 / 75
25% Ultimate Plus, 75% current food
Days 5–8
50 / 50
Equal mix of both foods
Days 9–12
75 / 25
75% Ultimate Plus, 25% current food
Days 13–14
100%
Full Ultimate Plus

For dogs with very sensitive stomachs, extend each phase to 5–6 days. Some temporary softening of stools during transition is normal and usually settles within the first week of full feeding.


Frequently Asked Questions

Can I switch between recipes if my dog's needs change?

Yes. All five recipes share the same manufacturing process and similar ingredient foundations, so switching between them is straightforward. Transition over one week rather than two when switching within the range. Many owners start with a therapeutic recipe and move to Healthy Living once symptoms have resolved.

Do all five recipes require a prescription?

None of them do. All five Ultimate Plus hydrolysed recipes are available to purchase directly without vet authorisation. They are formulated to the same standard of protein hydrolysis as leading prescription diets but are not restricted to vet-only supply.

Why does Healthy Living cost slightly more?

Healthy Living is formulated as a premium everyday diet with a wider range of functional ingredients to support general immune, digestive, and skin health simultaneously. The difference is £5.99 per 1.5 kg bag compared to the rest of the range.

What is the sub-0.5 kDa figure and why does it vary between recipes?

Sub-0.5 kDa refers to the proportion of protein in the finished kibble that consists of dipeptides and tripeptides — the shortest possible protein chains, absorbed most quickly through the gut wall. A higher figure means a higher degree of hydrolysis. Each recipe's figure is calibrated to its health goal: the Dental Care recipe has the highest (69%) because reducing systemic immune load is critical for periodontal health; the Digestive Care recipe has the lowest (52%) because gut absorption benefits from a broader mix of peptide sizes.

Is it safe to feed these recipes long term?

Yes. All five recipes are nutritionally complete to FEDIAF European pet food standards for all life stages and are designed for everyday long-term feeding. Many dogs remain on hydrolysed food for life with no concerns.

Can I try a sample before committing to a full bag?

Yes. A sample pack is available from the hydrolysed range collection page — a good starting point if you are not sure which recipe your dog will prefer in terms of palatability.
