Old lady Palma has problems with her health

Today I took Palma to the vet. Unfortunately, he confirmed the presence of neoplasms in the mammary glands. In two weeks she will have surgery. Palma also began to walk very badly. Her paws hurt. I try to do everything that depends on me, but there is no cure for old age ...
When we got home I took some photos. For some reason, I wanted to change them to black and white. It seems to me, or even in the pictures you can see how hard it is for her to stand? My poor girl :( how painful it is for me. I did not know her as a puppy, I did not know her as a young cheerful dog. I've met her almost like that, but therefore I do not like her less. Do not be afraid to take age dogs. They are kind, wise and grateful.
