My dog is about 6 1/2 years old, has just been diagnosed with cancer and bleeding in the spleen. would arnica pills help to op the bleeding? I want to have a second opinion and/or find a holistic vetinarian. the vet says she saw a tumor/mass in his stomach and couldn't see the spleen. The red blood count was 305 and she says it should be 40% and that 30% means there is bleeding in the spleen. also, she thinks the cancer has spread, maybe even to the lymph nodes.
