Four Leaf Rover New Zealand Bovine Colostrum for Dogs

Natural Seasonal Allergy, Immune & Gut Support

One simple ingredient can support several areas of your dog's health that are closely connected. Four Leaf Rover Bovine Colostrum for Dogs provides a natural source of antibodies, lactoferrin, peptides, growth factors, and other beneficial nutrients to support seasonal comfort, a balanced immune response, and a healthy gut.

This single-ingredient dog supplement is made with bovine colostrum from 100% grass-fed, pasture-raised cattle in New Zealand. Colostrum is the nutrient-rich first milk produced after birth and naturally contains concentrated compounds that support immune and digestive health.

Four Leaf Rover keeps the formula refreshingly simple: rBGH-free New Zealand bovine colostrum with no fillers or inactive ingredients. Every batch is third-party tested to be free of growth hormones and antibiotics, and the colostrum is carefully processed at low temperatures to help preserve its naturally occurring compounds.

Why Bovine Colostrum for Dogs?

Colostrum is the nutrient-dense first milk produced immediately after birth. It differs from regular milk because it naturally contains concentrated antibodies, lactoferrin, proline-rich polypeptides, amino acids, growth factors, and other nutrients that help support early immune and digestive development.

Those same naturally occurring compounds make bovine colostrum a useful nutritional supplement for dogs. Four Leaf Rover provides them in an easy daily powder without combining the colostrum with unnecessary herbs, flavors, or fillers.

Seasonal, Immune & Gut Support in One Ingredient

Dogs encounter pollen, grasses, dust, and other environmental triggers throughout the year. Bovine colostrum naturally supplies lactoferrin, antibodies, and proline-rich polypeptides that help maintain a balanced immune response, making it a useful nutritional option for dogs with normal seasonal or environmental sensitivities.

Colostrum also naturally contains IgA antibodies and other beneficial compounds that help maintain a healthy intestinal lining and normal gastrointestinal function. Because digestive and immune health are closely connected, supporting the gut complements your dog's normal immune function as well.

Supports Healthy Skin from Within

Colostrum provides amino acids, lactoferrin, antibodies, and naturally occurring growth factors that help maintain normal skin integrity and a healthy skin barrier. This makes it especially relevant for dogs whose seasonal and environmental sensitivities can also affect skin comfort.

Grass-Fed New Zealand Colostrum with Careful Sourcing & Testing

Quality matters when choosing a bovine colostrum supplement. Four Leaf Rover sources its colostrum from 100% grass-fed, pasture-raised cattle on small farms in New Zealand. Just as importantly, the calves come first. They receive the colostrum they need during their first 12 hours before the remaining supply is collected.

The colostrum is carefully processed at low temperatures to help preserve its naturally occurring antibodies and other delicate compounds. Every batch is also third-party tested to be free of growth hormones and antibiotics, giving pet parents greater confidence in what they're adding to their dog's bowl.
