The physical examination is performed during each consultation.

Before the physical examination, the history of the dog is determined. As such, questions are asked about

• The general health status of the dog (does the dog drink remarkably more than before, how is the appetite, is the stool normal, does the dog cough)
• Treatments in the past (e.g. if a female dog, did she receive contraception; was the dog neutered)
• The tumor (how fast did it grow, how does the dog react to the tumor (ignore it, chew on it, scratch), does it occasionally bleed, when did you notice the tumor).

After this, the veterinarian does a thorough general physical examination of the dog: he checks the vascularization of the mucous membranes of the mouth and eyes, evaluates the size of the lymph nodes, listens to the heart and lungs, palpates the abdomen to identify tissue masses, as well as anomalies of the organs.

The tumor itself is judged based on its size, the firmness and motility.
