My beloved shepherd Ooma is only 11 months old... And I have noticed a big fatty lump with approx. A 2-inch diameter. I will check this out immediately at the vet but I'm hoping to receive some information and advice on these fatty lumps. Has anyone had a similar experience? I'm worried sick about her well being. And the worst part is is I'm a student and can't afford to pay for cancer treatment. My god.
