IAMS Proactive Health Large Breed Dry Dog Food — Chicken, 30 lb | Joint Support & Digestive Care

IAMS Proactive Health Large Breed Dry Dog Food is a chicken-first, large-breed kibble formulated to support strong muscles, healthy bones and joints, digestion, immune health, and a shiny coat.

This 30 lb bag of IAMS Proactive Health for Large Breed Adults blends real chicken as the primary protein with wholesome grains, targeted nutrients, and tailored kibble size to meet the needs of full-grown large-breed dogs. The recipe avoids fillers and artificial flavors and is designed to support five key health areas—muscle maintenance, energy, digestive balance, immune support, and skin and coat condition—while including nutrients that contribute to a healthy heart.

How does this formula support strong muscles and healthy weight?

The recipe uses high-quality animal proteins (real chicken and egg) to provide the amino acids large breeds need to maintain lean muscle mass. Balanced calories and nutrient-dense ingredients help preserve strength without promoting excess weight gain.

• Real chicken listed as the #1 ingredient for concentrated protein
• Egg protein adds complementary amino acids for muscle repair
• Appropriate calorie density for adult maintenance in large breeds
• Designed kibble size encourages slower chewing and portion control

What supports bone and joint health in large breeds?

This formula includes controlled calcium levels and natural sources of glucosamine and chondroitin to help support skeletal strength and joint resilience over time. Those components are chosen to complement the higher body mass and unique skeletal needs of large-breed dogs.

• Optimized calcium for adult large-breed bone maintenance
• Natural glucosamine and chondroitin for joint support
• Minerals and vitamins that contribute to overall skeletal health
• Kibble designed for large mouths, reducing wear on teeth and jaw

How does the food help digestion and nutrient absorption?

IAMS includes a blend of natural fibers and prebiotics to promote a balanced gut environment and regular digestion. Better digestive health supports nutrient uptake and steady energy levels throughout the day.

• Prebiotic fibers to nurture beneficial gut bacteria
• Natural fiber blend for stool quality and regularity
• Digestible carbohydrate sources for steady energy
• Formulation aimed at reducing digestive upset in adult dogs

Will this recipe support my dog's skin, coat, and immune system?

The Proactive 5 design targets skin and coat condition with essential fatty acids and antioxidants to help support a healthy immune response. Regular feeding as directed can contribute to a glossy coat and overall vitality without relying on artificial colors or flavors.

• Omega fatty acids and balanced fats for skin and coat health
• Antioxidants included to support immune function
• No artificial flavors or fillers; ingredients aligned with AAFCO natural definitions
• Complete and balanced formulation for adult maintenance
