My shitzu has lumps & bumps all over his body that come and go. They are not cancer had biop done.
But they don't know what ist is?
When he gets them he is not himself & when they disappear he is fine.
Dog has lime, also liver disease and is on Hills KD & LD food.
Do you have any thoughts.
He is only 6 years old.
I am not sure why the biopsy did not give you an answer? This usually gives a diagnosis. vetcare
