Hill's Science Plan Large Breed Adult Dog Food with Chicken

Hill's Science Plan — Large Breed Adult Dog Food with Chicken | 2.5kg & 14kg

Veterinarian recommended. ActivBiome+ Multi Benefit. Supports immune system, healthy joints & lean muscles. The science built for dogs that live large.

Hill's Science Plan Large Breed Adult Dog Food with Chicken is the complete dry food formulated for the specific physiological needs of large breed adult dogs — dogs weighing 25kg and above, aged 1 to 5 years. Large breed dogs are not simply scaled-up medium dogs. Their joints bear significantly greater mechanical load, their muscle mass requirements are fundamentally different, their immune systems face distinct challenges, and their caloric needs per kilogram of body weight are lower than smaller breeds. Hill's addresses every one of these differences: real chicken as the primary protein, ActivBiome+ technology delivering 3 essential benefits, and a formula clinically formulated to support the three areas large breed adults need most — immune system health, joint integrity, and lean muscle maintenance. Not artificially preserved. No synthetic colours. No artificial flavours.

One 14kg bag provides 37 days of food for a 40kg large breed dog. From the brand that has helped over 14 million shelter pets worldwide find a forever home. Available in 2.5kg and 14kg. From Hill's Pet Nutrition, available at petfast.shop in Egypt.

Why Hill's Science Plan Large Breed Adult with Chicken Is the Best Choice

• Veterinarian recommended — the #1 vet-recommended dog food brand globally — Hill's Science Plan is developed by over 220 in-house veterinarians, PhD nutritionists, and food scientists; it is the most recommended adult dog food brand by veterinarians worldwide across all breed sizes
• ActivBiome+ Multi Benefit — 3 Essential Benefits precisely targeting large breed adult needs — the three benefits are not generic; they are specifically chosen to address the three most clinically significant long-term health challenges for large breed adult dogs: immune system function, joint health, and lean muscle maintenance
• "Supports immune system, healthy joints and lean muscles" — the exact core claim on the packaging; this triple-benefit positioning is unique to the large breed adult formula and reflects the distinct health priorities of dogs over 25kg
• Real chicken as primary protein — chicken is the first named ingredient; it provides the complete amino acid profile required for lean muscle protein synthesis and maintenance — particularly critical for large breed dogs whose higher muscle mass requires more daily dietary protein to maintain
• Precisely formulated for large breed adults (25+ kg, 1–5 years) — caloric density, protein:fat ratio, glucosamine and chondroitin sulfate levels (for joint support), and kibble size are all specifically calibrated for large breed adult physiology
• Glucosamine & chondroitin sulfate for joint support — large breed dogs carry significantly more body weight across their joints than small or medium breeds; the formula includes glucosamine and chondroitin sulfate — the clinically established building blocks of cartilage — to support joint integrity and healthy joint function throughout the 1–5 year adult prime phase
• 100% balanced & healthy — meets all established nutritional standards for complete large breed adult dog food; no supplementation required
• Not artificially preserved, no synthetic colours, no artificial flavours — clean-label formula
• 14kg bag = 37 days of food for a 40kg dog — confirmed on the product infographic; excellent real-world feeding duration claim that justifies the 14kg bag investment

Product Details & Features

The 3 Essential Benefits — What They Mean for Large Breed Adults

Benefit 1 — Immune System Support Large breed dogs live 8–12 years on average — a shorter lifespan than small breeds, but a lifespan during which immune system support remains critical throughout. ActivBiome+ works at the gut microbiome level, feeding beneficial bacteria that produce short-chain fatty acids (SCFAs) that modulate immune cell activity and strengthen the gut barrier. Combined with the formula's antioxidant complex (vitamins C, E, and other antioxidants), the immune support system operates at two levels simultaneously — microbiome-mediated immune modulation and direct antioxidant protection of immune cells.

Benefit 2 — Healthy Joints Joint health is the #1 long-term health challenge for large breed adult dogs. The mechanical reality is straightforward: a 30–50kg dog carries 30–50kg of body weight across joints every step of every day. Over years of normal activity, this creates significant wear on joint cartilage — particularly in high-motion joints like hips, knees, and elbows. Hill's addresses this through:

• Glucosamine — a natural component of healthy cartilage; supplemented at clinically relevant levels to provide the substrate cartilage cells use to maintain and repair the joint matrix
• Chondroitin sulfate — works with glucosamine to maintain cartilage water content and resilience; also inhibits cartilage-degrading enzymes that contribute to joint deterioration
• Omega-3 fatty acids (EPA) — the anti-inflammatory omega-3 EPA reduces joint inflammation that drives cartilage degradation and pain in active large breed dogs
• Controlled caloric density — maintaining ideal body weight is the single most effective intervention for large breed joint health; the formula's caloric density is calibrated to support lean body condition without excess weight that compounds joint loading

Benefit 3 — Lean Muscles Large breed dogs carry significantly more muscle mass than small and medium breeds — and require proportionally more dietary protein to maintain it. The formula's protein profile (with real chicken as primary protein) is calibrated to support lean muscle protein synthesis and maintenance across the 1–5 year adult phase. "Lean" is the operative word — not bulk muscle, but the functional, metabolically efficient lean muscle mass that supports large breed physical performance, healthy metabolism, and healthy body composition.

Why Large Breed Adults Are Different — The Nutritional Science

A generic "adult dog food" calibrated for medium breed maintenance is nutritionally suboptimal for a 30kg+ dog. The caloric density is too high (promoting weight gain that accelerates joint deterioration), the glucosamine and chondroitin levels are insufficient, and the kibble geometry is incorrect. Hill's Science Plan Large Breed Adult is the correct formula for dogs in this weight class.

Glucosamine & Chondroitin — Joint Support Built Into the Formula Rather than requiring separate joint supplement purchases — which add cost, complexity, and over-supplementation risk — Hill's builds the clinically relevant levels of glucosamine and chondroitin sulfate directly into the formula. For large breed adult owners who would otherwise purchase joint supplements separately, this is a meaningful cost and convenience advantage. The formula delivers joint support in every bowl, at every meal, without additional intervention.

Lean Muscle Architecture — The Protein Strategy The protein profile is designed for lean muscle maintenance, not bulk building. For large breed adults in the 1–5 year prime phase:

• High biological value chicken protein provides all essential amino acids for muscle protein synthesis
• The leucine content (the primary amino acid trigger for muscle protein synthesis) is specifically maintained at levels that support muscle maintenance without excess
• The protein:fat ratio is calibrated to support lean body condition — adequate protein for muscle, controlled fat to prevent the excess weight accumulation that accelerates joint deterioration

Frequently Asked Questions

Is this suitable for all dogs over 25kg? Yes — Hill's Science Plan Large Breed Adult is formulated for all adult dogs with a body weight of 25kg or more, aged 1 to 5 years. For dogs aged 6 and above, Hill's offers the Science Plan Large Breed Mature/Senior formula with an adjusted nutritional profile for older large breed dogs.

Does this formula contain glucosamine? Yes — Hill's Science Plan Large Breed Adult contains glucosamine and chondroitin sulfate at levels clinically relevant for supporting joint health in large breed dogs. These are built into the formula — no separate joint supplement is required.

Why does this have 3 essential benefits while the puppy formula has 5? The puppy formula's 5 benefits reflect the additional nutritional demands of the growth phase (brain development, bone development, growth support, plus immunity and digestion). The adult formula's 3 benefits are precisely targeted at the three most critical long-term health priorities for large breed adults: immune function, joint health, and lean muscle maintenance.

Can I feed this to my large breed puppy? No — large breed puppies (under 12–24 months, depending on breed) have fundamentally different nutritional needs, particularly regarding calcium:phosphorus ratios and caloric density for growth. Use Hill's Science Plan Large Breed Puppy for dogs under 12 months (up to 18–24 months for giant breeds). Switching to the adult formula prematurely can negatively affect skeletal development.

How long does the 14kg bag last? As confirmed on the product infographic: one 14kg bag provides approximately 37 days of food for a 40kg dog at the recommended daily feeding amount. For lighter large breed dogs (25–30kg), the bag will last correspondingly longer — approximately 50–60 days.
