There is a knot in one's heart near the trachea in Rothwell's neck.

There are papules near the trachea in Rottweiler dogs, which may be as follows:

1, folliculitis or sebaceous bursitis: This is a common skin disease caused by infection or inflammation of hair follicles or sebaceous glands. Rottweilers may be more susceptible to this disease because of wrinkles and long hair.

2, lymph node enlargement: the dog's lymphatic system is similar to that of human beings, and lymph nodes are one of its main components. If the dog has inflammation or infection, the lymph nodes may become swollen.

3. Lipoma: This is a common benign tumor, which usually grows in subcutaneous tissue. Rottweilers may be prone to lipoma due to age and other factors.
