A litter of healthy puppies is every breeder's joy and pride. Experienced breeders know what preparation is necessary for this. The male must produce sufficiently active sperm, the bitch must produce fertile eggs.
Bitches also create a calcium reservoir that promotes fertility and prevents fertilized eggs from being rejected. If the bitch is not healthy or not sufficiently supplied with important nutrients, she may not even eat because the conditions for a healthy rearing of her puppies are not given. In the mating phase, during gestation and rearing, special attention must be paid to the optimal care of the bitch. An optimal supply of all necessary substances is also necessary for the healthy growth of the puppies.
