Treatments for Mesothelioma in Dogs

Firstly, your vet will ask about your dog’s symptoms. Secondly, your vet will ask about any circumstances where your dog could have come into contact with toxins or poisons.

Thirdly, a full physical examination will be carried out. Blood and urine tests will be taken. Additionally, X-rays of the chest area and fluid samples can help to diagnose the condition.

Generally, treatment targets your dog’s symptoms. For example, your dog may need to spend time in hospital to drain any fluids that have accumulated in any cavities.

While your dog is recovering, it is important to provide them with a quiet and calm environment. Also, your dog’s exercise might need to be limited, especially if they are having breathing problems. Your vet can help formulate a safe schedule for your dog.
