The dog has a tumor-like substance on its hind leg and needs surgery as soon as possible. First, it is necessary to confirm whether the growth is a tumor or a mass caused by a skin disease. If it is a lump caused by a skin disease, it can be disinfected if the lump does not ulcerate, and it will be observed for a few days to see if it will heal on its own. If it is a tumor, and the tumor grows quickly, it is recommended to perform surgical removal as soon as possible, and then do pathological sections to confirm whether it is benign or malignant. If your dog has the above symptoms, you need to seek medical attention promptly and go to the hospital for a series of examinations to prevent the condition from getting worse.

Precautions after a dog develops a tumor:

1. If the owner suspects that the dog has a tumor, he can first treat the tumor to determine whether the dog has a tumor. There is pain.

2. The owner needs to observe the size of the tumor to see if there is a tendency to grow larger. If it becomes larger, you need to go to the pet hospital for a B-ultrasound examination in time, and then use surgery to remove the tumor.

3. If the tumor is a benign, non-metastatic tumor, such as mast cell tumor or histofibroma, a normal life expectancy can be achieved through treatments such as surgery and chemotherapy.
