Lymphoma is one of the most common forms of cancer that can be contracted by a dog. This form of cancer, also known as non-Hodgkin's lymphoma or lymphosarcoma, is a malignant cancer that involves the lymph nodes and lymphoid system. The final stage of Lymphoma, known as Stage 5, usually occurs when the cancer spreads to the bone marrow of your pet. If your dog displays any of the following signs or symptoms, take him to the vet immediately.

Just like in humans, lumps on your dog are not normal. If you discover a round, hard lump on your dog's abdomen, back, neck or armpit that hasn't been there in the past, there might be a problem. Keep in mind that some older dogs develop fat deposits that are softer than problem lumps. If you are unsure, consult your veterinarian.


Loss of Appetite or Nausea

All dogs love meal time, and it is a known fact that they are highly motivated by the prospect of eating. If your dog begins to eat noticeably less or not eat at all, chances are he is not feeling well. If your dog begins vomiting or gagging after meals or more frequently throughout the day, there is a good chance your dog is experiencing a serious health problem.


Weight Loss

A telling sign of canine health is rapid weight loss. If your dog's appetite isn't completely gone, but he is still losing weight rapidly, it is typically a sign that there is something seriously wrong. Noticeable weight loss is one of the major signs of canine Lymphoma.



When a dog becomes lethargic, begins acting depressed and stops enjoying the activities it once derived great pleasure from, chances are there is an underlying health problem. If you suspect that your dog is sick, begin monitoring his daily activity and if you see a major change, consult your veterinarian.



Dogs are typically warm, so determining if your dog has a fever can be difficult. If your dog has displayed one or more of the other symptoms on this list, you may want to take your dog's temperature. A recurring fever or a fever that lasts for more than a day or so should be taken seriously. A canine fever is generally not a "stand-alone" symptom and typically means you have a sick dog that needs medical attention.
