“I will have a home soon. I am quite a timid person and that is why I want to buy a protection dog. Which breed is best suited to the role of guardian? Where can you buy such a dog? Is winter, I should let him out of the house for the night, or rather (because of the cold) he must stay in the apartment?”
First of all, I suggest, to buy a book on dog breeding. Since the decision to buy a pet has already been made, you should report to the Kennel Club in Warsaw. You will receive information there, where to purchase a protection dog. This is important, because buying a dog from a breeder guarantees, that the animal will be purebred, healthy and vaccinated against diseases in young puppies. But as for the question, whether in winter the dog should be kept in the apartment or in the yard, it is a matter of habituation of the animal. Generally, short-haired dogs should be kept indoors, and long-haired-in properly built kennels. Detailed information can be found in books on dog breeding.
