Lymphoma in dogs can be treated and put into remission with Chemotherapy. Dogs treated with prednisone alone survive 4-6 weeks on average. The caveat to this is that Chemo is not guaranteed. Best to ask the vet and check your finances. BEST of LUCK with your buddy!! I'm hunting with two now, number 8 and number 9. Yes, the first seven broke my heart, but it was worth it.
