I lost one of mine at just 6 years to cancer, she too was still full of life but there was no hope using chemo with her type of cancer.
You can use nutrition to (hopefully ) keep her well for longer, but it's by no means a replacement for chemo and may not be effective in all dogs, but perhaps something you might want to look into, to use alongside her chemo.

I would give you a big word of caution though, there are a lot of quack cures out there, if you see something that interests you, Google the item for any actual research that's been done.
My girl was given only weeks to live by the oncologist, her cancer was so aggressive, but she went on to have 7 months of very good health with no symptoms what so ever, until the last week of her life, the oncologist said she'd never seen anything like it.
Cherish your girl every day, and try not to focus on the end, every morning I would say to Celli, yes you have cancer, yes it is going to kill you, but it's not happening today.
my thoughts are with you x
