I've been dreaming about a dog for a long time. And the day came when we went to pick up my new friend. It was the best day of my life, I was very nervous. We had to get up at 4 am to get there on time. As we drove, I looked out the window and imagined our life together now, how we would play together, and how I would train him. When I saw him, he was tired and scared, because he was driving to Moscow from Voronezh all night.To this day, I feel like crying when I remember our first meeting.And from that beautiful day (June 1, 2019), our story began.
