Lymphoma in dogs symptoms are often mistaken for other illnesses and may vary depending on the form of lymphoma your dog has developed (multicentric, gastrointestinal, cutaneous). Often times, your dog will develop swollen lymph nodes, sometimes seen around the neck or in the armpits. When touched, your dog may not even flinch. Swollen lymph nodes are signs of many other illnesses such as allergies or bacterial infections. However, as time goes on, other symptoms along with swollen lymph nodes may indicate a much more serious illness known as lymphoma.
Always talk to your veterinarian if your dog’s lymph nodes are continually swollen or other symptoms of lymphoma in dogs appear. The sooner lymphoma is caught, the higher chance of remission. Early stages of dog lymphoma are known to have about 80-90 percent chance of remission if treated right away.

Symptoms of lymphoma in dogs may vary depending on the form of lymphoma present. The following is a break down of the common forms of lymphoma in dogs and their symptoms:
Lymphoma of the central nervous system (CNS) – Although uncommon, CNS is accompanied with neurological symptoms such as loss of coordination, seizures or behavioral changes.
Cutaneous lymphoma – This is also an uncommon form of lymphoma in dogs. Your dog may appear to be itchy and dry, scaly skin may appear. As it progresses, hair loss and visible lesions may be present. Often times, large, inexplainable bruises may also appear.
Multicentric lymphoma – Multicentric lymphoma is the most common form of lymphoma in dogs. It may start out as painless, but large lymph nodes. These may be found under the jaw, around the groin, behind the knees and in the armpits. As time goes on, the liver or spleen may become enlarged. This may cause the abdomen to become distorted.
Mediastinal lymphoma – This is lymphoma of the respiratory system. Symptoms include coughing, difficulty breathing and fluid build up in the lungs. Often times, mediastinal lymphoma is mistaken for respiratory disease or heart failure.
Gastrointestinal lymphoma – This form of lymphoma may appear in many different areas of the gastrointestinal system. The small and large intestines, stomach and rectum may all become infected. The most common symptoms of gastrointestinal lymphoma in dogs include vomiting, diarrhea, melena and lethargy. This is the second most common form of lymphoma in dogs.
