Thank you kindly my friends. Your words brings me much comfort.
My little Libi went through a lot... I saved and adopted her when she was just a small puppy. There were four puppies at first. Their mother was a stray dog hanging around the neighborhood and gave birth to them in some abandoned house. When I first found them I started bringing them food and water. I had two dogs of my own at that time and couldn't take them myself, but was trying to figure out how to find them a permanent home and take them of the street. One day when I came home went as usual to see them, but they were nowhere to be found. After long search I found just one puppy with a bullet hole in it's head! I buried it and was going to leave when another puppy showed up whimpering. She had bullet wound in one leg. I took her home, nursed her to health and eventually decided to keep her giving her name Libi (in English that could be written "Libbie" I guess). Never seen the mother and other two puppies again.
We had many happy years with Libi afterwards. There were some problems along the way - she was hit by a car once, but went with only light injuries. Three years ago she was operated from the mammary glands tumor, but recovered nicely and we never had the cause to think that disease would return in any form up until two weeks ago. What pains me the most is the fact that it came without warning and so fast we couldn't do much for her except to stop her pain in the end. And it had to be my decision. I was heartbroken on Monday when she was receiving infusions. I was with her all the time, but had to leave the room for a moment. She tried to fallow me though she almost couldn't walk and the veterinarian had to hold her until I returned. She was very devoted and loving dog.
This is one of the last pictures I have of her taken last summer. She wasn't alone, as you can see I have two more dogs and love them, but I guess she was most special to me...
