Lymphoma in dogs is a form of cancer that affects the lymph nodes and other lymphoid tissue. These tumors are most often found in the spleen, liver, and bone marrow, but they can occur in any organ or tissue that contains lymphatic tissue.
Lymphoma typically affects older dogs (usually between 6 and 10 years old), but can appear in younger dogs as well.
The symptoms of lymphoma vary based on where it develops in your dog’s body. For example, if it develops in the spleen or thymus gland (which are near each other), you might notice that your dog has trouble breathing because one of these organs may have become swollen due to cancerous tumors growing there.
As far as treatment goes, there are two main options: chemotherapy or radiation therapy. Both options will require regular follow-up appointments with your veterinarian so they can monitor how well your pet responds to treatment over time.
