Otto’s chirurgical costs

Hi, my name is Bianca and I'm Otto Mother. He's a senior dog, 13 years exactly. He started going blind four years ago. In 2010 he suffered an accident in his left eye And It had to be removed. Due to stress and trauma, it began to easily go blind and Manifest symptoms of OCD, simply rode large pieces of stones, now he has no teeth for about 8 years. Due to age has respiratory and kidney problems, is totally blind and partially deaf. The problem with blindness can be solved by surgery but in our country, Romania, pet treatments are very expensive. We can barely afford us as people to go to the doctor. Medical and treatment costs can reach up to 3k E, We can afford to cover only a small part of the cost. He's my first dog and I want to give him a little comfort and Relief For the last years he has to live. Please help him!
