This dog did not come to the yard.
Tarzan caused a scandal in a local courtyard, where he found refuge.
When he was a puppy, he had to learn to live alone, to look for food, shelter, and sometimes human communication. So he wandered into one of the private sectors of the Moscow region. And for some time he was even sailing there until he began to pose a threat to local residents, although there was absolutely no reason for that.
Tarzan turned out to be a stately big handsome guy. He is active, playful, cheerful, assiduous and very attentive to everything. Absolutely not aggressive is sociable with everyone. He simply could not do evil to anyone. And his strength and power was perceived as a threat and wanted to get rid of the stray dog from the territory. So Tarzan got to the shelter.
While the time was waiting for the locals to calm down, Tarzan was already used to the shelter. Naturally, letting him go again in free swimming, where he could be harmed, or perhaps worse, no one would. Now Tarzan, vaccinated, healthy, neutered, strong, cheerful little boy, is ready for a completely new, but no less desirable home life from this.
