The forage has to contain all necessary nutrients, but the dog doesn't need a flavoring variety. The dog can constantly receive the same forage if only it has been optimum made.
The owners of female dogs may wish to start breeding. The arguments for this may be such advantages as the birth of a child for the female's health.
We want to say at once that this argument is untenable, and only for this reason should not be engaged in breeding. There is no evidence that a female dog who has never had a puppy has a greater propensity for inflammation of the uterus or mammary glands than the female who already gave birth. True, in some, very rare cases, childbirth and growing puppies makes her self-confident;
However, the danger that the female will give her bad constitutional signs to her offspring is decidedly greater. There are also a number of dog owners who think of breeding the Bernese Mountain Dogs to improve their financial situation. This is possible unless, if you show the female as rarely as possible and only at nearby exhibitions, grow broods of puppies in some corner of a small apartment and save on the nutrition of the mother and the puppies, disregarding the possibility of complications requiring veterinary treatment, and, finally, if costs for a long trip to a suitable male producer are eliminated.
If you want to breed, as befits a serious, self-aware dog breeder, then, by drawing a line in the budget at the end of the year, you will find that the income does not much exceed the expenditure. The only reason for breeding Bernese Mountain Dogs should be only love for the breed and the will to continually improve the material available for breeding.
In Russia, the females of a Bernese Mountain Dog is allowed to knit by a third heat - not earlier than at the age of 18 months. Before that, they should be demonstrated at least at two national exhibitions of the Russian National Club "Bernese Mountain Dog" to a special judge and then admitted as selected producers for further breeding. The prerequisite for participation in the selection are "very good" and "excellent" - for females and only "excellent" - for males, obtained at these exhibitions. These conditions are valid, however, only for members of the Russian National Club "Bernese Mountain Dog".
Each club can develop its own guidelines. For selection it is necessary to present the pedigree and the conclusion about dysplasia of the hip joints. There is an opinion that females comes in heat in spring and autumn. This is not true. The often expressed judgment that summer litters are healthier and stronger than winter litters is also not confirmed by experience. Determining here is the feeding and keeping of puppies. If you want to grow winter droppings, you need to have a well-insulated light and heated room. The floor in it should be rough and easy to clean. If the flooring is too smooth, the puppies can slip during their wild games and get a sprain.
