I am not expert about the topic.I would certainly try the steroid therapy as this is what is needed to keep them OK for another few months. I would also suggest feeding 3 to 4 times a day as well to help him keep his weight.

Most of the time, lymphoma in dogs appears as “swollen glands” (lymph nodes) that can be seen or felt under the neck, in front
of the shoulders, or behind the knee. Occasionally, lymphoma can affect lymph nodes that are not visible or palpable from
outside the body, such as those inside the chest or in the abdomen. Other symptoms include vomiting, diarrhea, loss of
appetite, weight loss, lethargy, difficulty breathing and increased thirst or urinations. Cutaneous lymphosarcoma can cause
redness or flakiness of the skin, ulceration (especially near the lips and on the footpads), itchiness or lumps in the skin. Clinical
signs will vary depending on the stage of the disease, volume of tumor and anatomic location of the lymphoma.
While we understand how lymphomas form, we still do not understand why. There is growing evidence and much speculation
that environmental factors such as exposure to pesticides (especially herbicide 2,3-D) ( Read New York Times Article: Lawn
Herbicide Called Cancer Risk for Dogs) . A new study published in April 2012 finds that utilizing a chemical lawn service to achieve a
lush lawn is likely causing malignant cancer in many pet dogs. In the study, researchers identified 263 dogs with
biopsy-confirmed canine malignant lymphoma (CML), 240 dogs with benign tumors, and 230 dogs undergoing surgeries
unrelated to cancer. Then, they asked the pet owners to complete a 10-page questionnaire. Scientists found that dogs with
malignant lymphoma were 70 percent more likely to live in a home where professionally applied lawn pesticides had been used.
Dogs with the serious malignancy were also 170 percent more likely to come from homes where owners used chemical
insecticides to combat pests inside of the home.
There is some speculation that strong magnetic fields may increase the incidence of lymphoma in dogs, but there is currently no
absolute proof of this. Evidence has emerged of a possible genetic correlation in dogs because of the higher prevaience of
lymphoma in certain breeds, but further studies need to be performed to determine the exact risk factors involved in canine

Lymphoma is one of the most common cancers seen in dogs. Although there are breeds that appear
to be at increased risk for this disease, lymphoma can affect any dog of any breed at any age. It
accounts for 10-20% of all cancers in dogs.
