Thirteen-year-old Pointer mix - Had skin disease, but hair is coming in again!

My beloved dog is a thirteen-year-old female Pointer mix weighing 22 kg.

She developed a lump on her abdomen, so I took her to the vet and was told that it appeared to be some kind of canine cancer. She was operated on twice, six months ago, but now she has another lump and I am worried.

She is not taking any medicine at present.

~A later message~

I have been giving her four pills twice a day for about one month.

She has more appetite and can go for walks that last about two hours.

Besides that, in the reddened places in her skin, where she had lost her hair, the hair is growing back in again, and now she is so well that you wouldn't think she was old. I attribute all this to my giving her Pinfenon.
