Official Japanese ingredient statement
Kept in Japanese to avoid changing the meaning of the manufacturer’s label. Match this text against the latest package before feeding.
ラム(肉)*2、玄米*3、ラムミール*4、粗挽き米、米糠、オートミール*3、エンドウタンパク、タンパク加水分解物、鶏脂*1、ビートパルプ、大豆油*1、ひまわり油*1*5、フィッシュオイル*1*6、ビタミン類(A、B1、B2、B6、B12、C、D3、E、コリン、ナイアシン、パントテン酸、ビオチン、葉酸)、ミネラル類(カリウム、クロライド、セレン、ナトリウム、マンガン、ヨウ素、亜鉛、鉄、銅)、アミノ酸類(タウリン、メチオニン)、酸化防止剤(ミックストコフェロール、ローズマリー抽出物、クエン酸) * ミックストコフェロールで保存 *2 ビタミンB群、亜鉛含、*3 食物繊維含、*4 グルコサミン、コンドロイチン含、*5 オメガ6脂肪酸含、*6 オメガ3脂肪酸含
Purpose, intended life stage and differences within the range
Nutro Natural Choice Medium and Large Breed Senior Lamb and Brown Rice, 2 kg is dry dog food from Mars Japan Limited. Intended stage: senior medium/large breeds aged seven years+, expected adult weight at least 10 kg, as declared by the seller. Stated nutritional purpose: complete food intended for senior dogs. Net content: 2 kg. JAN: 4562358786808. Manufacturing-country verification: United States, as declared by the matched seller. A Japanese manufacturer’s address, the food’s factory country and the origin of each raw ingredient are separate facts. A Japanese-language pack or brand name alone does not establish Japan-made status.
Lamb-first senior food also contains rice/oats, legumes, chicken fat and fish oil. No explicit small-kibble statement was verified, so the common medium/large rule applies. The maker’s fat 13.0% minimum is recorded.
Read the stage wording, nutritional purpose, kibble declaration and full recipe together. Flavour, stage and selected weight identify a specific product. A few matching protein/fat figures cannot establish identical formulations across the range. Complete-food wording, where stated, is retained for its declared stage rather than expanded to stages absent from the maker’s directions. Product-relative health-maintenance descriptions are not individual veterinary treatment claims.
Complete ingredients and the evidence behind the checklist
English reading aid preserving all declared ingredient groups, order and parenthetical details:
lamb (meat)*2, brown rice*3, lamb meal*4, coarsely ground rice, rice bran, oatmeal*3, pea protein, hydrolysed protein, chicken fat*1, beet pulp, soybean oil*1, sunflower oil*1*5, fish oil*1*6, vitamins(A, B1, B2, B6, B12, C, D3, E, choline, niacin, pantothenic acid, biotin, folic acid), minerals(potassium, chloride, selenium, sodium, manganese, iodine, zinc, iron, copper), amino acids(taurine, methionine), antioxidants(mixed tocopherols, rosemary extract, citric acid) * mixed tocopherols for preservation *2 contains B vitamins and zinc, *3 contains dietary fibre, *4 contains glucosamine and chondroitin, *5 contains omega-6 fatty acids, *6 contains omega-3 fatty acids
The complete original Japanese ingredient statement is also retained on this product page. Processing ingredients, colourants, minerals, vitamin groups and antioxidants are not omitted to make a shorter-looking or apparently simpler recipe. A flavour word is not a reliable substitute for that statement. The first ingredient, the first member of an animal-ingredient group and the food pictured on the pack can refer to different things.
Presence categories follow the complete declaration, including chicken fat, fish oil, legumes, grains and vegetables/fruit beyond the flavour name. Egg is not classified as dairy; a lamb flavour does not certify chicken-free composition. Natural-ingredient or no-colourant wording does not remove the declared vitamin/mineral groups or antioxidants and is not expanded to an unrestricted additive-free claim.
An unchecked ingredient category does not certify zero trace presence, absence of factory cross-contact or suitability for a particular dog. Where a generic term such as animal oils/fats does not name the species, an unknown species is not supplied. For a medically necessary restriction, use the full current pack statement and product/lot details when asking the maker and veterinary team. The checklist organises documented facts for searching and comparison; it does not approve a food for an individual animal.
Guaranteed analysis, representative analysis and energy units
The individual official guaranteed-analysis table follows. “Minimum” preserves Japanese 以上 and “maximum” preserves 以下; the numbers are not converted into exact measured average contents.
| Item | Manufacturer declaration |
|---|---|
| Protein | 23.0% minimum |
| Fat | 13.0% minimum |
| Crude fibre | 4.0% maximum |
| Ash | 10.0% maximum |
| Moisture | 9.0% maximum |
The maker’s separately headed “Other contained components” table retains its stated limits and units:
| Item | Manufacturer declaration |
|---|---|
| Vitamin E | 60IU/kg minimum |
| Selenium | 0.35mg/kg minimum |
| DHA | 0.05% minimum |
| Omega-3 fatty acids | 0.5% minimum |
| Omega-6 fatty acids | 3.5% minimum |
| Alpha-linolenic acid | 0.1% minimum |
| Chondroitin | 350mg/kg minimum |
| Glucosamine | 100mg/kg minimum |
A separate representative-analysis table was not verified in this individual declaration.
Protein at least 23% and fat at least 13% are lower guarantees. In particular, a fat minimum cannot be used as a fat ceiling for a veterinary restriction. Fibre, ash and moisture retain their own original guarantee boundaries. Percentages, IU/kg and mg/kg are different units. A vitamin declaration in IU/kg is not a percentage, and a representative mineral figure is not silently substituted into the guarantee table.
Energy: 350 kcal per 100 g. The explicit per-100-g basis and any approximate qualifier are preserved. This is distinct from total tray or seller-set energy. Moisture is included in the declared percentages. Wet and dry label percentages are not ranked as if they were measurements on the same dry-matter basis. A moisture maximum is not the measured moisture needed to produce a precise dry-matter calculation. Preserve both numerical boundaries and the stated weight basis before comparing figures.
Feeding guide, kibble classification and storage
The individual manufacturer page provides a feeding guide as an image. Open this product’s original feeding table. Check the body-weight, puppy-age and per-day headings. A shared capacity-range guide is distinct from another flavour or stage. Numbers have not been guessed or transcribed from unreadable text; compare the original table with the received package before using it. The table is in Japanese; use the page’s life-stage and unit explanations as a reading aid.
Kibble: medium/large browsing classification; an explicit small-kibble statement was not verified. The catalogue checks small only when small-kibble wording is explicit. Otherwise medium/large is the site’s consistent browsing classification, not a measurement. The dog illustration, breed name and external bag dimensions are not used to invent millimetre-sized grains. A category does not guarantee comfortable chewing or safe swallowing for every individual dog.
Before using a feeding table, distinguish daily total from each meal, product net weight from the seller’s purchase set, and age/body-weight headings from a similarly named formula. Treats and toppers contribute to the whole diet; the principal food’s guarantee alone does not describe everything consumed. Keep fresh drinking water available. Use the received directions and veterinary guidance when adjusting for body condition, activity or illness instead of extrapolating a missing table or giving an unsupported individual prescription.
After opening, the maker advises avoiding direct sunlight, high heat and humidity, using the food promptly and sealing securely to prevent insect entry. An unopened best-before date is not an after-opening storage period; check the received pack instructions.
Online analysis is dated information. A label, recipe, portion guide or package can change while a merchant photograph remains unchanged. Keep the received name, JAN, lot and best-before details available when querying a discrepancy. Where an exact direction was not verified, it is explicitly left unrecorded; an authoritative-looking number is not inserted from memory or another flavour. Health concerns require the individual dog’s history and current product declaration, not a single filter, age badge or ingredient term.
Differences from the Rakuten listing and the actual purchase unit
The name, formulation, stage, capacity and JAN were matched; recipe, guaranteed analysis and energy conditions were checked. Origin is attributed to the corresponding merchant declaration. The seller declares fat 12.0% minimum versus the current maker’s 13.0%. The maker gives 350 kcal per 100 g and the seller qualifies the number as approximate. Current official guarantees and full recipe are recorded.
The sale is the single 2 kg product. The purchase button links to the corresponding Rakuten merchant product. This page includes affiliate advertising; the site may receive a commission from a purchase. Check current price, stock, selected variant, pack count, shipping fee, delivery region and best-before details at the merchant before ordering. Where maker and seller declarations differ, the discrepancy is recorded so that the buyer can confirm the actual offered package rather than treating the two statements as one identical formula.
The product image comes from the corresponding linked Rakuten listing and is credited to Rakuten Ichiba. Photographs and illustrations help identify a food; they cannot supply ingredient or feeding text that is absent or unreadable in an image. Packaging can change, so confirm the offered name, JAN and life stage with the seller where the picture differs from a current declaration. The received ingredient statement and directions remain necessary. A Japanese Rakuten listing does not establish international delivery, customs admissibility or permission to import the food into another country. Ordering, payment, delivery, returns and live seller terms are handled by the merchant.
Review date and original sources
The individual official information and corresponding Rakuten listing were reviewed on 18 September 2026. This is dated product-label information rather than a diagnosis or ration prescription. Match the received name, JAN, life stage, full ingredients, analysis boundaries, feeding guide and handling directions before relying on a stored entry. If the declaration changes, use the updated maker information and current physical package. During treatment or where veterinary dietary restrictions apply, bring the complete current label to the responsible veterinary team.
How to use this information
Start with the life stage and feeding purpose shown on the package. Compare guaranteed protein and fat together with energy per 100 g; a lower percentage alone does not make one food better for every dog. Product names such as “beef” or “fish” do not necessarily mean a single animal-protein source, so use the ingredient flags and original statement together.
If your dog has an allergy, illness or prescribed diet, do not rely on this comparison page alone. Check the current package and contact the manufacturer or your veterinarian.
