Evidence: research-led. Dog Product Reviews has not run feeding, palatability, stool, skin or allergy trials on these foods. We checked the linked official UK product pages, WSAVA food-selection guidance, UK Pet Food definitions and PDSA food-trial guidance on 21 September 2026. Labels and manufacturer instructions are evidence of intended use, not proof of an individual dog’s outcome. Check the exact current pack before feeding. How we assess products.
PRO PLAN Medium Adult Sensitive Digestion Lamb Dry Dog Food, 14kg
Complete dry food for adult medium dogs in the 10–25kg band.
Evidence: research-led
Main drawback: Despite the lamb name, the published composition includes poultry protein. It is not a hydrolysed diet, a prescription food or a substitute for a vet-led allergy trial.
Skip if: Puppies unless the exact product is labelled complete for growth or puppy use.
There is no evidence-based rule that every Cockapoo needs a grain-free, high-meat or breed-labelled diet. Start with a food labelled complete for the dog's life stage, make sure its stated size range fits the dog's expected or ideal adult weight, and use the pack feeding guide as a starting point rather than a fixed prescription.
WSAVA's food-selection guide recommends looking beyond marketing and ingredient-list impressions to who formulates the diet, quality control, nutrition research and whether the company can answer technical questions. UK Pet Food explains that a complete food supplies all required nutrients in the correct proportions; a complementary product does not do that by itself.
The four options below are therefore different fit choices, not a claim that one recipe will suit every Cockapoo. Persistent diarrhoea, vomiting, weight change, itching or recurrent ear problems need veterinary assessment rather than repeated food switching or an assumed grain or chicken allergy.
Quick answer:
For an adult Cockapoo in the 10–25kg band with no diagnosed condition: Purina Pro Plan Medium Adult Sensitive Digestion Lamb is a complete dry option with an exact manufacturer size range and feeding table. It still contains poultry protein, so it is not an elimination diet.
For a healthy adult weighing 11–25kg: Royal Canin Medium Adult is a complete standard adult diet with an activity-based feeding guide. It is not a hypoallergenic or veterinary diet.
For a smaller adult and smaller bag: Lily's Kitchen Adult Small Breed Chicken & Duck is a complete 2.5kg option. It is grain-free, but that is a recipe feature—not evidence that it is better or allergy-safe.
For complete wet feeding: Forthglade Chicken with Butternut Squash & Vegetables is labelled complete and can be fed alone. Confirm the complete version because Forthglade also sells complementary “Just” trays.

What actually matters here
Complete-food status for the relevant life stage; complementary foods are not shortlisted as sole diets.
Exact size and age fit rather than assuming the word Cockapoo determines nutritional needs.
A usable manufacturer feeding guide and clear current UK product identity.
Evidence and quality-control questions recommended by WSAVA, not ingredient-list or “premium” marketing alone.
A retailer destination checked against the exact name, life stage and current UK pack.
Who this is for
Owners choosing a complete everyday food for a generally healthy Cockapoo.
Owners comparing dry, small-breed dry and complete wet formats without assuming one is universally superior.
People willing to weigh portions, monitor body condition and change food gradually.
Who should skip
Puppies unless the exact product is labelled complete for growth or puppy use.
Dogs on a veterinary or prescription diet unless the vet approves a change.
Dogs with persistent digestive, skin, ear or weight symptoms until a vet has investigated the cause.
Owners running a food-allergy trial: use the exact diet and duration prescribed by the vet, not this general shortlist.
A Cockapoo does not have one automatic “best” diet
Cockapoos vary because both parent breeds and the Poodle size used in the cross vary. Age, ideal adult weight, neuter status, activity, body condition, health and the rest of the daily diet all affect the choice. A 7kg adult and a 16kg adult should not automatically receive the same product or portion because both are called Cockapoos.
For a healthy dog, the practical first filter is a complete diet for the correct life stage and size band. If the dog is thriving on its current complete food, has a stable healthy body condition and normal stools, a more expensive recipe is not automatically an upgrade.
How to read a UK dog-food label
Look first for complete and the life stage. UK Pet Food says a complete product can provide the full daily diet, while a complementary product must be fed with something else. This distinction is more important than whether a tray looks meaty or a bag uses words such as natural or premium.
Ingredient categories such as “meat and animal derivatives” do not by themselves prove poor quality. UK Pet Food's labelling guide explains that manufacturers can list ingredients by category or by specific names. WSAVA likewise warns that ingredient lists can be misunderstood and do not reveal ingredient quality or the expertise behind a formulation.
Useful manufacturer questions include: who formulates the food and what are their qualifications; what quality-control checks are used; whether the company conducts or publishes nutrition research; whether it supplies a typical analysis and calorie value; and whether someone qualified can answer nutrition questions.
Sensitive digestion and suspected food allergy are different decisions
A retail product called “sensitive digestion” is not an allergy test. The Purina pick is included because its exact size range and complete-food status fit many medium adults, not because this site has verified a medical benefit. It contains poultry protein, and the other three picks contain poultry too.
PDSA describes a food trial as a vet-led process using a prescribed special diet for at least 6–12 weeks with nothing unapproved added. Proteins, as well as some other ingredients, can cause allergies. Follow the vet’s exact plan rather than selecting a trial diet from this shortlist.
Do not treat itchy skin, ear problems, vomiting or diarrhoea by hopping between commercial foods every few days. Those signs have several possible causes. Record the food, treats and symptoms, then take that history to the vet so any trial is controlled and nutritionally appropriate.
How much should an adult Cockapoo eat?
There is no reliable single gram figure for the breed. Products differ in energy density, and Cockapoos differ in ideal weight and activity. Use the feeding table on the exact pack for the dog's ideal, not automatically current, weight. Weigh the daily ration on kitchen scales and include treats, chews and toppers in the total.
For example, Royal Canin currently lists different portions for low, moderate and high activity at each target weight. Purina also publishes activity-based quantities. Those figures are starting points; monitor body condition and weight, then ask the vet or veterinary nurse for an individual target if the dog is gaining or losing.
If dry and wet foods are mixed, do not feed the full daily allowance of both. Use the manufacturer's mixed-feeding guide or ask the company for the correct combination.
Puppies, seniors and weight-management diets
A puppy needs a complete growth/puppy food matched to expected adult size; none of the adult picks should be substituted just because its kibble looks small. UK Pet Food advises following the puppy product's guide and changing gradually when the dog reaches the appropriate maturity.
Senior is not a single nutritional diagnosis. A healthy older dog may need different energy intake, while kidney, gastrointestinal, dental or weight problems may call for a veterinary diet. Do not cut protein, choose a prescription food or reduce portions substantially from age alone without professional advice.
Change food gradually and monitor one variable
Follow the manufacturer’s transition instructions for the exact new food, unless your vet advises otherwise. Change gradually, keep other food changes limited and contact the vet if symptoms develop or persist; a generic transition timetable cannot resolve a medical problem.
Do not label diarrhoea or vomiting “normal” and push through it. Stop and ask the vet promptly if signs are severe, repeated, include blood, accompany pain or lethargy, affect a puppy, or the dog cannot keep water down. Contact the practice when milder signs persist rather than continuing to experiment.
Quick questions before you buy
What is the best food for a Cockapoo in the UK?
There is no universal breed winner. Choose a complete food for the dog's life stage and stated adult-weight band, then use its feeding guide and monitor body condition. This shortlist separates medium-adult, small-breed dry and complete-wet options so the fit is visible before the affiliate click.
Does a Cockapoo need grain-free food?
No. A Cockapoo does not need grain-free food solely because of its breed, and grain-free is not a general quality or allergy guarantee. If an allergy is suspected, ask a vet about a controlled food trial rather than removing grains at random.
Complete dry food for adult medium dogs in the 10–25kg band
Despite the lamb name, the published composition includes poultry protein. It is not a hydrolysed diet, a prescription food or a substitute for a vet-led allergy trial.
Standard complete dry diet for healthy adults weighing 11–25kg
It is a standard retail formula, not a veterinary gastrointestinal or hypoallergenic diet. It is also outside its stated size band for a smaller Cockapoo below 11kg.
Smaller adult Cockapoos needing small-breed kibble and a smaller bag
It contains chicken and duck. Its grain-free formulation is not proof of superior nutrition and does not make it suitable for a dog with a suspected poultry allergy.
Complete wet feeding for adult dogs aged one year and over
The brand also sells complementary “Just” recipes in similar trays, so check the received label says complete. This recipe contains chicken and its grain-free label is not an allergy claim.

Best for: Complete wet feeding for adult dogs aged one year and over
Forthglade Complete Chicken with Butternut Squash & Vegetables Wet Dog Food

Pros
Complete adult wet food.
Published 395g tray format; verify the selected pack count.
Can be used as the sole diet when fed to its guide.
Cons
Contains chicken.
Heavier and bulkier per feeding day than dry food.
Similar complementary trays make label checking essential.
There is no universal breed winner. Choose a complete food for the dog's life stage and stated adult-weight band, then use its feeding guide and monitor body condition. This shortlist separates medium-adult, small-breed dry and complete-wet options so the fit is visible before the affiliate click.
Does a Cockapoo need grain-free food?
No. A Cockapoo does not need grain-free food solely because of its breed, and grain-free is not a general quality or allergy guarantee. If an allergy is suspected, ask a vet about a controlled food trial rather than removing grains at random.
How much food does a Cockapoo need daily?
Use the exact product's table for the dog's ideal weight, age and activity, then weigh the ration and adjust with professional advice based on body condition. There is no single accurate Cockapoo gram allowance because foods have different energy densities and adult sizes vary.
Are Cockapoos prone to food allergies?
This guide found no sound basis for claiming every Cockapoo is unusually allergy-prone. Itching, ear problems and digestive signs have multiple causes. PDSA says diagnosis normally uses a strict 6–12 week vet-led diet trial; proteins are common triggers, and unapproved treats can invalidate the trial.
Can a Cockapoo eat wet food every day?
Yes, if the exact wet food is labelled complete for the correct life stage and the daily amount meets the dog's needs. Complementary wet food is not a complete sole diet. If wet and dry are mixed, reduce each using a mixed-feeding guide rather than serving two full allowances.
What should a Cockapoo puppy eat?
A Cockapoo puppy should eat a complete puppy or growth food matched to expected adult size. Follow that product's age-and-weight feeding table and ask the vet or breeder when to move to adult food; do not use an adult pick merely because the kibble is small.
How do I switch a Cockapoo to new food?
Follow the exact manufacturer’s gradual-transition instructions unless the vet gives a different plan. Keep other dietary changes limited and do not dismiss vomiting or diarrhoea as normal. Seek prompt veterinary advice for severe, repeated or persistent symptoms.

Weighing the daily ration is more reliable than estimating it with a cup, especially when treats and toppers are also fed.
