Hi hoping someone who has a dog who has mast cell tumour and their experience. My 9 yr old bearded collie cross had a lump removed a few weeks ago. We knew it was worrisome but pathology has come back as grade 2 mast cell tumour. We are going into talk to the vet Monday about next steps. We are in between where if it was grade 1 then removal of the lump and monitor and stage 3 where it's pretty aggressive and chemo is recommended. So we are trying to figure out whether we should go the chemo route for him. He is such a nervous dog, gets stressed easily and is very prone to stomach upset and refusing food. I have found plenty of information online from a vets perspective but wondering if anyone else who owned a dog with this and had to make the same decisions. would mind sharing their experiences?
