It is complicated to detect cancer at an early age in pets. Let us get rid of a common myth. However, there are 10 signs of cancer in dogs you can look for in your pets. If it is not then, these signs may help detect another medical condition. Also, it is critical to remember that a pet can be very sick inside without showing any sign or symptom outside.

As per the National Canine Cancer Foundation, one out of three dogs develop cancer. Cancer can occur in both purebred and mixed breed dogs. There is no age for cancer. Canine cancer can happen at any age. However, it generally occurs in elder dogs. Early detection is the key when dealing with cancer. If you catch cancer in its early stage, you can treat it through chemotherapy, surgery, immunotherapy, and radiation. Here we have the top 10 symptoms which will help you detect cancer in your dog. So, learn to spot the signs here:
1. Abnormal swellings that keep growing continuously

The most obvious sign is a mass that keeps growing under the skin. The surgeon will recommend having it removed and biopsied. It will be easier to decide on the actual treatment process. Once or twice a month, take a few minutes to feel your pet’s body for any lumps, bumps, or abnormal swelling. Check for swollen lymph nodes, which can be a sign of lymphoma. Lymph nodes are located throughout the body but most easily detected around the jaw, shoulders, armpits, and behind the legs. Note the size and location of any bumps or nodes to check any change in shape over time.
2. Non-Healing Sores

The skin wounds do not seem to heal despite oral antibiotics or applying ointments. It could also be a no-healing area near a nail. If your pet has an open wound that is not healing, it could be a sign of something more serious, such as an infection or cancer.
3. Weight Loss

A sudden loss in weight cannot be explained only by a diet. Common causes could include a tumour along the intestine. If there is no change in the diet or food, but your pet is gaining or losing weight, this could be a sign of illness. Weight loss or weight gain can indicate a possible tumour in the stomach. Another related symptom could be chronic vomiting or diarrhoea.
4. Loss of Appetite

A mass along the intestines may make your dog feel uncomfortable. One of the first things a pet will then do is skip its meal or stop eating. Is your pet eating more or less than usual? Are they trying to eat foods they were uninterested in previously? Drastic changes in your pet’s appetite could be a sign of cancer.
5. Unable to Eat or Swallow

A lump in the neck could be putting pressure on the oesophagus the food pipe. A tumour in the mouth or neck can make it difficult for your pet to eat or drink.
6. Bleeding or Discharge

Although bleeding from the nose does not necessarily mean cancer, it is a common sign of cancer of the nose. Consult your veterinarian if your pet experiences any unexplained bleeding or discharge from any opening. Bleeding is a common sign of cancer and other illnesses. Oral cancer can cause gums to bleed. Nose cancer can cause the nose to bleed.

7. Offensive Odour

A foul smell from the mouth can be a sign of oral cancer. Biopsies of a large mass near any opening show that it has cancer. There may be some wounds or nodes from which pus comes out their foul odour gives a doubt of some severe issue. A culture may show different bacteria growing in there.
8. Long-Time Cough

For many reasons, dogs might have a persistent and continuous cough. For younger pups that were recently adopted or placed in boarding, a persistent cough could be a sign of kennel cough. In older dogs, a persistent cough could indicate a tumour near the heart or lung cancer. Because of the bleeding and the pressure on the heart, they certainly face difficulty while exercising.
9. Persistent Lameness or Stiffness

We see lame pets every single day, but luckily, they rarely have cancer. However, bone cancer can cause pain and lameness, along with swelling along the leg. You may find that your pet is limping on one foot or no longer wants to walk or exercise. Persistent lameness or stiffness can be a sign of osteosarcoma or bone cancer.
10. Difficult Breathing, Urination, or Defecation

That could be due to the pressure on the respiratory system, urinary system, and digestive system. A tumour near the oesophagus, nose or lungs can block airways, making it harder for your pet to breathe. Dogs and cats can develop tumours in their urinary tracts, which can make it difficult to urinate. Similarly, they can have trouble defecating or have sustained a foul odour from the rear the mass near the anus might be the culprit.
