First, is that dogs with splenic lumps tend to bleed from the lump - sometimes in dribs and drabs, sometimes continuously - until surgery is done to remove the spleen. Ideally, yes, we wouldn't operate on an anaemic animal but these are typically catch 22 situations: if a dog is anaemic because they are bleeding from the spleen, and the only way to stop the bleeding is to operate to remove the spleen. Typically these are emergencies and need to be done right away, but please take your vets' or their emergency counterparts' advise on this as I don't know the case in question (we don't review bloods or radiographs for the same reason).
Vets have found that giving fluids to these patients can be helpful because what red blood cells there are, are carried better around the body when the circulation is supplemented. Some such patients even need blood transfusions, or blood substitutes, but your vet will discuss their plan for this kind of thing with you.
Removing splenic masses are big operations and do carry a degree of risk. However, there may also be considerable risk attached to not performing the surgery. Ask your vet what they expect of the long term prognosis.
When surgery goes well, it is possible to make the patient feel much better very quickly.
