Product Information
HT 42d LARGE DOG contains precise levels of key nutrients to support the first stage of gestation in breeding females and helps with fetal development. Nutrients include: Tyrosine, beta-carotene, vitamin A and C, folic acid, and omega 3s EPA/DHA.

From the 1st day of heat to the 42nd day of gestation, the breeding female’s daily energy requirements equal adult maintenance needs. Recommended daily rations should be monitored to avoid excess weight gain during this period of gestation, as this could lead to difficulties during birth.


Intestinal immunity decreases during gestation. A targeted nutritional profile can help support digestive function during this specific life stage. HT 42d LARGE DOG contains LIPs (Low Indigestible Proteins), a blend of fibres, omega 3 fatty acids EPA & DHA, and prebiotics.

The appetite of the breeding female may be quite delicate during gestation. A highly palatable formula can help to satisfy her fussy appetite. Nutritional components include: High quality raw materials, a specially adapted formula, unique kibble size, shape, texture & density, and carefully selected flavours & aromas.
