A loss of appetite

Fever is indeed the common symptom of many diseases but it is also one of the most obvious to consult your veterinarian as we would naturally consult our doctor in such a case. The normal temperature of a dog is between 38 ° C and 39 ° C.

A change of behavior

A change of behavior in your dog is again a most revealing sign about his suffering and his distress! The dog has kept the instinct of animals living in nature, whether at the top or bottom of the food chain, and it induces him not to reveal his pain, for fear of being easy prey for his predators or for his contenders to his territory or to a female … If he no longer shows any enthusiasm for activities that once amused him, such as playing with his master, calling for hugs or simply snuggling against him; that he is crouching in a corner of the house away from solicitude, you must react! His behavior change may be a sign of cancer.

Pale gums

The color of the dog’s gums is a good indicator of good oxygenation and circulation. You can see it the moment you read this paragraph if your companion is at your side: they must be pink and if you press with a finger part of his gum, it should normally go from white to pink in two seconds maximum. Thus, pale gums permanently mean a deficit of blood flow that can be linked to serious diseases, see cancer in dogs.

Bad breath

Dogs can be affected by cancers of the oral cavity, resulting in particular in bad breath (halitosis). Among the cancers of the oral cavity in dogs, the most common oral tumor is malignant melanoma. The loss of teeth, the presence of an oral mass, lesions or pain to open the mouth are other symptoms.

To conclude

Among the 12 signs of cancer in dogs that we have just detailed, some are more revealing like the formation of a mass on the skin, others like behavior change you will ask to be more attentive. Whether you notice one or more of these symptoms simultaneously, you should definitely consult your veterinarian! No doubt is allowed for early treatment of cancer. This vigilance advice does not relieve the veterinarian of the annual check-up. Since the costs of treating cancer are relatively high (radiotherapy and surgery in this case), we strongly advise you to subscribe to mutual health insurance for dogs.
