Pet's info: Dog | Siberian Husky | Female | spayed | 9 years and 1 month old | 45 lbs
Fine needle aspirate was inconclusive in lump on my dog. Is a biopsy in order? Super healthy 9 year old husky. Has had lump in question for about a year and has not gotten any bigger to my knowledge. No change in her behavior either. She did however fight the needle kicking and screaming when the sample was taken. Thoughts?

I would recommend having an biopsy done on the lump on Nanook. There are types malignant cancers that can't be diagnosed with a fine needle aspirate, and can only be diagnosed with a biopsy. It's always important to have any suspicious lumps diagnosed, so in case it is a malignant cancer, it can be treated right away. It does happen that dogs will not show any signs of being sick from cancer until after the cancer has spread or a tumor has ruptured. I think having it biopsied is a good idea.
