Immune System & Intestinal Flora in Dogs

The immune system, not only in dogs, is located more than 80% in the intestines. It supports the body in defending itself against environmental influences and contributes to the normal functioning of the organism. Various factors such as age, feeding, stress, pregnancy, previous illnesses, surgical procedures, or increased stress can impair normal immune function and the balance of the intestinal flora.
A disturbed intestinal flora can lead to nutritional intolerances and impair the dog's well-being. In such cases, it is advisable to provide targeted support to the dog to avoid placing additional strain on the organism.
VITAL immun » Natural support for immune function and intestinal flora
Already after birth, the puppy receives valuable antibodies and nutrients from the mother's colostrum, which protect it during the first weeks of life. However, colostrum can also make a valuable contribution to supporting normal immune function later in life. It contains natural probiotic ingredients that contribute to maintaining a balanced intestinal flora and can thus counteract nutritional intolerances.
Agaricus Blazei Murill extract is a valuable medicinal mushroom valued in veterinary medicine and helps support the natural immune system.
Mumijo extract contributes to vitality and supports normal cell function – especially valuable during periods of increased stress.
Propolis extract is known for its valuable ingredients and supports normal immune function.
Colostrum from selected dairy farmers
DOG FIT by PreThis® VITAL immun contains high-quality probiotic colostrum from the first milk of cows kept on selected farms. This natural source of valuable nutrients supports the normal function of the organism and the maintenance of a balanced intestinal flora.
The combination of Colostrum, Agaricus Blazei Murill, Mumijo, and Propolis makes VITAL immun a valuable addition to daily nutrition – ideal for support during periods of stress, in old age, and with special requirements such as a disturbed intestinal flora.
Our products are complementary feed for dogs. They do not replace a veterinary examination or treatment. If your dog has any health problems, please contact your vet.
